Does nitrogen-enriched gasoline create additional pollution?
The practice of adding nitrogen to gasoline has been done for many years. The EPA requires auto fuel fold in the US to contain detergents to help reduce pollution. In some cases nitrogen is added to reduce carbon build up in the engine and to improve performance. Some worry that nitrogen-enriched gasoline contributes to smog, acid rain and other environmental problems in the form of nitrogen oxide. However, not enough research had been done and many say most nitrogen emissions from autos is caused by incoming nitrogen in the air reacting with gasoline and not from additives. Portland Home and Garden Show offers nothing but Green Ghettos Aromatherapy for the Home Article for Better Living Show Blog from the American College of Healthcare Sciences
You may have seen the term “aromatherapy” on product labels, or even as part of spa services or in advertising. But perhaps you’re wondering, “What does aromatherapy really mean?” Translated literally, aromatherapy is the use of aromas for their healing properties. It is “the controlled use of essential oils to promote the health and vitality of the body, mind and spirit,” as Shirley Price, a noted clinical aromatherapist, further explains in her book Aromatherapy for Health Professionals. So what does essential mean? Essential oils are the distilled or expressed product of volatile components synthesized by various plant tissues of a single plant species (the healing components). Simply, essential means that these distilled or expressed oils contain the essence or the fragrant part of the plant. Bottled Water – A Great Idea (for some!)
Next to selling air, bottled water has to be the best idea to come along at the last half of the 20th century! Best that is for the folks selling it but not perhaps so much for the rest of us. A typical 8-ounce bottle sells for $1.00. There are 128 ounces or 16 bottles in a gallon. Sixteen dollars for a gallon of water is no bargain unless you are in the middle of Death Valley or are dealing with an emergency.
Bottled water is often municipal water that has received some additional filtration or treatment. The additional treatment is similar to home water treatment systems offer and the filtration is pretty much the same as the filter on your refrigerator or in the filtered water pitcher in the fridge. The “natural sources” some bottlers claim are often nothing more than a well. Granted there are some city water supplies with “funky” water – moldy odors, excess chlorine, or old metal pipe taste. Home water treatment or filtration systems are perfect for those folks. For the record, no one wants to drink “pure water”.
The Religion of Sustainability For many people, the journey to going green has just begun. But for those of us that have preached this message for some time, it’s a natural way of life. It is not burdensome, rather a harmonious set of actions that flows with the world around us. And we want everyone to drink from the cup. However, are we getting in our own way? Is sustainability going the way of religion? The Abrahamic religions of the world came from one origin. And through the years they split into Judaism, Christianity, Islam, the Bahai Faith and a few other smaller ones. Each of these taking a separate road with diverging beliefs and rules. And each of these has splintered even more as their moral compasses give way to legalism. It seems that human nature drives us to break away from others that are not totally in agreement with us and start our own group. We pick at a single thread in a garment rather than embracing the garment itself.
Environmental Health Concerns: A Challenge for Each of Us
How can we connect with garden clubs across our fifty states and carry the message of health as it relates to the environment? We can begin to reconcile behaviors of high technology versus allegiance to the self; understand social and cultural conditions that influence the life of an individual and community.
Do you know about the “dead zone” at the mouth of the Mississippi created by runoff of chemicals, fertilizers and silt from urban lawns, streets and agriculture land?
Do you know what a waste management system is? A flush system and lagoon? Are you concerned having runoff from fields and cattle pens into creeks and eventually into rivers?
What's better for the environment, sewers or septic systems? Most people don't have a choice when buying a house as to whether they want to be on a sewer system or septic system unless the community is looking to switch to a sewer system. Each work fine in terms of the environment if they are well maintained. Both systems are designed to handle and treat so-called “blackwater” (wastewater from toilets) and “graywater” coming from our sinks, showers, dishwashers and laundry machines. On-site septic and community-wide sewer systems work in similar ways, utilizing micro-organisms to filter out bacteria, viruses and other disease-causing pathogens before releasing the cleansed water back into the environment. In either case, improperly treated sewage can contaminate water sources and spread deiseases such as hepatitis. It can also lead to increased nitrates in local water supplies, which is dangerous for infants, pregnant women and those with already compromised immune systems. What is Leachate? OK – leachate is not generally thought of as small talk at cocktail parties – but it could be! And no – it is not a by-product of leeches. Leachate is basically contaminated water or liquid produced whenever a material is placed on the ground and either precipitation falls on it or it has its own liquid content. Basically, if it touches the ground it probably produces leachate. And let’s face it – everything is made of chemicals! Therefore leachate contains chemicals. So what’s the big deal? Well, there are a couple of issues here. First, chemical contamination in leachate goes somewhere right? It just goes away. If you use Google Earth© and punch in “away” it will take you about 8,513 miles from Portland, Oregon to Away, China. But that’s probably not where your leachate will end up. Leachate generally travels either down (due to that pesky gravity) or it moves sideways due to the nature of the local soil type and geology. If it goes down, the leachate will eventually hit the groundwater table. If it moves sideways it will eventually pop out in a stream, creek, or other body of water.
Do TV screens broadcast harmful electronic emissions? No, children sitting too close to the TV isn’t known to cause any health issues. due to electronic emissions. Nor does it cause vision problems other than eye fatigue and strain which can be remedied with turning off the tube. Of course, excessive TV viewing by kids can cause health problems indirectly. According to the Nemours Foundation, children who consistently watch TV more than four hours a day are more likely to be overweight, which in and of itself can bring about health problems later. Also, kids who watch a lot of TV are more likely to copy bad behavior they see on-screen. The bottom line is moderation. Limit your children's time watching television and teach them that it is for occasional entertainment. Then kick them outside and get them active. Face to Face marketing is your best bet for 2010 What’s the best marketing investment you can make in 2010? Trade and consumer shows. Face to face marketing will be the best use of marketing dollars while the economy is in recovery, and the reason is simple – those who visit consumer shows, have money to spend (hence the term consumer show). As an apparel company owner and marketer, my sales are a direct reflection of my marketing tactics – and I’m putting my money and time into shows. My Internet sales are seriously down; my show sales are way up. How do I account for this? I’m able to present my brand, my philosophy of service, my benefits and pricing strategy (including haggling), direct to consumers. All those print ads, radio spots, web specials, banner ads and email marketing is being ignored. And frankly, so are the social marketing initiatives – everyone is hoping this is the golden child of marketing – and guess what – you still have to sell to your customers the good old fashioned way – with service, knowledge and a kind smile. I know, we all want to click a button, hit send, and our sales go through the roof – sorry to burst your bubble. Trade and consumer shows take practice and strategy, you can’t sit there and read your favorite book and hope someone will tap you on the shoulder. You must have sales goals, marketing strategy, info gathering ability, a booth that stands out, and qualified sales staff on hand. I’ve been around shows and events for 20 years, those who complain that their sales stink, were the ones with a scowl on their face and a crappy attitude, those that worked the floor, were courteous and aggressive, did great. Here are some tips to a successful trade show: Toxins in Breast Milk Researchers have found that people living in developed countries carry toxins in our bodies due to constant exposure from our surroundings. Some of these chemicals end up in breast milk and are in turn passed along to newborns. In a 2005 New York Times Magazine article, Florence Williams states that breast milk tends to attract heavy metals and other contaminants due to its high-fat and protein content. Make Our Milk Safe (MOMS), a nonprofit engaging in education and advocacy to eliminate toxic chemicals from the environment and in breast milk reports; “Along with its antibodies, enzymes and general goodness, breast milk also contains dozens of compounds that have been linked to negative health effects,” which lists Bisphenol-A (BPA, a plastic component), PBDEs (used in flame retardants), perchlorate (used in rocket fuel), perfluorinated chemicals (PFCs, used in floor cleaners and non-stick pans), phthalates (used in plastics), polyvinyl chloride (PVC, commonly known as vinyl) and the heavy metals cadmium, lead and mercury as leading offenders. However researchers from Ohio State and Johns Hopkins suggest that the amounts in breast milk are very small and we should be concentrating our efforts on reducing indoor air sources of VOCs. And the CDC feel that the benefits of feeding newborns breast milk far outweigh the risks. Chlorine in Tap Water Thousands of municipalities add chlorine to the community's drinking water toget rid of contaminants like nitrates, arsenic and pesticides. It is used primarily because it is inexpensive and very effective for this purpose. But what is the downside? Researchers have found a link between chlorine in drinking water and higher incidences of bladder, rectal and breast cancer. This seems to be caused shen the chlorine reacts with organic compounds in the water to make trihalomethanes, which encourage the growth of free radicals. Bottled water is no solution as much of it comes from these municipal water sources as well. The easiest way to get rid of the chlorine in your drinking water is to install a carbon-based fileter system in your home. Grab a Volunteer MopAs I start on this new exercise of blogging I feel it is only fitting to write my first post about the greatest man I’ve known – my father. I was lucky to see my father almost ever day of my life as I went to work with him shortly after leaving college. Image being able to eat lunch with your dad each day and learn from his years of experience. I am humbled by the man he was and the gift I was given. Shortly after his death I left the family business to start my own business producing the Energy Trust Better Living Show and following my passion for starting sustainable garden programs at elementary schools. And I bring to the latter, the ethos that my father taught me. He was a humble man that was never interested in being in the limelight. He just showed up and did the work.

Dear EarthTalk: Could it really be true that a single large volcanic eruption launches more greenhouse gases into the atmosphere than the amount generated by all of humanity over history? Dear EarthTalk: It seems like more products are being packaged in #5 rather than #2 plastic today, and my local recycling agency won’t take #5. I’ve also heard that #5 plastics are more toxic, which concerns me more than the recyclability issue. Which plastic is the better choice? Dear EarthTalk: A friend of mine in Connecticut raves about the “Green Drinks” events she attends there every month to meet up with other eco-interested locals. How can I find out if there are any such gatherings in my area? Dear EarthTalk: Which parts of the United States are or will be hardest hit by global warming?

Dear EarthTalk: Is it better to drive an older, well-maintained car that gets about 25 miles per gallon, or to buy a new car that gets about 35 miles per gallon? Dear EarthTalk: Is it true that some baby bottles contain chemicals that can cause health problems for babies? If so, how can I find alternatives that are safer? Dear EarthTalk: How much “old growth” forest is left in the United States and is it all protected from logging at this point? Dear EarthTalk: I want to convince my high school to go green. What would it cost for a school to switch to all recycled paper products and all energy efficient lighting? Dear EarthTalk: With all the talk of desalinization of ocean water for drinking, what do we know about the impacts this might have on climate, ocean salinity and other natural processes?

Week of 09/21/2008 Week of 09/14/2008 Dear EarthTalk: What’s the story with animal cloning? Is the meat industry really cloning animals now to “beef up” production? Dear EarthTalk: I’ve read that household cleaners contain cancer-causing toxic ingredients. What should I do, then, to keep my house clean but also safe for my kids? Dear EarthTalk: I’ve heard that increasing eco-awareness around the world has now extended itself to the afterlife, whereby burials can even be “green.” Is that true? Dear EarthTalk: What’s the deal nowadays with aerosol spray cans? I thought that the ozone-depleting chemicals used in them were eliminated back in the 1970s. Is this true? If so, what is now used as a propellant? Are aerosols still bad for the ozone layer? Dear EarthTalk: Everyone knows we should recycle metal, glass and plastic cans and bottles, but what about all the lids, tops and caps? I see people recycling plastic bottles, for example, with their caps on, but I've always been told to thrown them out. Is that wrong? Dear EarthTalk: I am considering solar panels for my roof to provide heat for my hot water and possibly to do more than that. Are there some kinds of solar panels that are better than others? How do I find a knowledgeable installer? Dear EarthTalk: My body doesn’t tolerate cheese well. Are there dairy-free cheeses that will be easier on my constitution and better for the environment, too? Dear EarthTalk: Can those energy-efficient compact fluorescent light bulbs that are popular now cause headaches because of the flickering they do? I converted my whole house over last fall and both my kids were complaining of headaches on and off. Dear EarthTalk: What is “community based tourism” and how does it purport to safeguard pristine places? Dear EarthTalk: How often do I really need to change my car’s oil? Conventional wisdom has always put it at every 3,000 miles to prevent engine wear, but isn’t changing oil that frequently wasteful and unnecessary? Also, what is the "greenest" and longest-lasting oil I should use? Dear EarthTalk: How does congestion toll pricing, used in some cities around the world, cut down on vehicle traffic and promote green-friendly public transit? Dear EarthTalk: I’ve read that plastic bottles are not always safe to reuse over and over as harmful chemicals can leach out into the contents. I’m wondering if the same issues plague Tupperware and other similar plastic food storage containers. Dear EarthTalk: What’s going on in the music industry with all the CDs and plastic CD holders undoubtedly generating a lot of plastic waste? Dear EarthTalk: What are the major environmental issues that our next president, be it Obama or McCain, will have to confront? Week of 7/20/2008 Week of 7/13/2008 Week of 7/6/2008 Week of 6/29/2008 Dear EarthTalk: How is it that hydrogen can replace oil to run our cars? There seems to be a lot of controversy over whether hydrogen can really be generated and stored in such a way to be practical? Week of 6/22/2008 Dear EarthTalk: What is “cogeneration” as a means of providing heat and power? Week of 6/15/2008 Dear EarthTalk: Summer’s going to be a scorcher this year, and I’d like to know how I can keep cool indoors without just running my energy-hogging air conditioners all the time. Any tips? Dear EarthTalk: Is it true that the DEET used in most mosquito repellents is toxic? If so what problems does it cause? And what are some non-toxic alternatives for keeping mosquitoes at bay? Dear EarthTalk: I want to offer my employees a 401(k) plan that is socially and environmentally responsible. Are there such plans and, if so, where do I look? Dear EarthTalk: Recent NASA photos showed the opening of the Northwest Passage and that a third of the Arctic’s sea ice has melted in recent years. Are sea levels already starting to rise accordingly, and if so what effects is this having? Dear EarthTalk: What’s available now in lawnmowers that are easier on the environment? My yard is too big for one of those “reel” mowers, and I’m no longer a spring chicken, so I have to buy something that runs on more than human power. What’s out there? Dear EarthTalk: The 2008 Summer Olympics in China are drawing a lot of attention right now for political reasons. I’ve heard, though, that one ray of light is China’s effort to make the event as green as possible. What’s going on in that regard? Dear EarthTalk: How is it said that we are “losing winter” because of climate change? It didn’t seem so last winter, when it even snowed in places for the very first time. Dear EarthTalk: What initiatives are taking place on college campuses to reduce the footprints of these large users of energy and other resources? Dear EarthTalk: What is the status of wetlands in North America? Years ago I remember that wetlands loss, due to development and sprawl, was accelerating fast, but I haven’t heard much on the topic of late. Dear EarthTalk: I really want to eat healthy and organic but am constantly traveling and on the go. How can I eat fast food without having to always end up at McDonalds and Burger King? Dear EarthTalk: Are sunscreens safe? Which ones do you recommend that will protect my skin from the sun and not cause other issues? Dear EarthTalk: What is the “clean tech” business sector and why have I been hearing that term so much lately? Dear EarthTalk: I’m planning a summer backpacking trip and was hoping to buy some of the latest green-friendly outdoor clothing. Where the best options out there today that wear as well as traditional items but without the environmental guilt? Dear EarthTalk: How is wind power faring in the U.S. now? Is more of it coming on line and becoming a larger percent of the grid? And what about some of the highly publicized efforts to build wind farms, such as in Cape Cod, Massachusetts. Has that been approved? Dear EarthTalk: I am getting married this summer and was wondering if you have any tips on how to make the festivities greener? Dear EarthTalk: My old computer finally bit the dust and I am in the market for a replacement. Are there any particularly “green” computers for sale these days? Dear EarthTalk: Are there any efforts underway to green the air travel industry? It seems to me that it must be one dirty business from a pollution standpoint. Dear EarthTalk: It is true that the carcasses of whales that wash up on shore are considered dangerous to humans because of the amount of toxins and chemicals in their blubber? Dear EarthTalk: I’ve found environmentally friendly shoes for myself, but have had trouble finding similar shoes for my kids. Are they out there? Dear EarthTalk: How can I find out which seafood to avoid if I am concerned about lessening my impact on the environment and avoiding consuming unhealthy pollutants? Dear EarthTalk: What makes those so-called “new urbanism” housing developments popping up around the U.S. more environmentally friendly than regular old suburban neighborhoods? Dear EarthTalk: How safe are the fire retardants that are used to quell forest fires across the American West? Dear EarthTalk: There are so many energy drinks on the market, but they all seem very high in sugar, coloring and preservatives. Are there any natural versions that offer a healthier kick-start? Dear EarthTalk: How or where can I recycle clothes that are too old or worn out for Goodwill? Dear EarthTalk: What are the conservation implications of all the wild colonies of escaped pet parrots that have turned up in and around some major U.S. cities? Dear EarthTalk: I know there’s a big debate now as to why we need bottled water at all, but is anyone addressing the incredible waste of plastic bottles by this industry? Dear EarthTalk: I’ve been hearing a lot about all the recycled materials being turned into handbags and purses. Are these bags actually fashionable? Dear EarthTalk: My pediatrician swears by those gel hand sanitizers for lowering the risk of my family getting sick during cold and flu season. But I’ve also heard that these products can be dangerous to kids if ingested. Are there any safer alternatives that work just as well? Dear EarthTalk: What are the environmental consequences of leather? Are there any good alternatives? Dear EarthTalk: I just read an article that said air fresheners contain chemicals that can cause health problems when inhaled. Are scented candles any better? Dear EarthTalk: I notice occasional solar panels on roadsides, powering individual streetlamps or signs. Is any research being done to expand on this idea and implant solar collectors in roads, parking lots or sidewalks to generate power in a similar but bigger way? Dear EarthTalk: As an online gamer, I spend a lot of time in front of my computer. What’s the environmental impact? And are “greener” PCs available? Dear EarthTalk: Vegetarians and vegans are so self-righteous about not eating meat and how meat eating is so bad for the environment. How true are these claims? Dear EarthTalk: As I understand it, coal that is used to fuel power plants and other industrial activity is a key culprit in pollution and climate change. So what is “clean coal” and is it really? Dear EarthTalk: Everybody says stop using plastic bags, but what about all the plastic, cellophane, cardboard and other materials used for packaging the food itself? What can we do to reduce how much of this unnecessary stuff comes wrapped around our food? Dear EarthTalk: I've been reading about various green festivals going on around the country and I want to attend some and get up to speed on environmental issues and products. What are some good ones and how do I stay on top of all the where’s and when’s? Dear EarthTalk: Is it possible to landscape my property in a green-friendly way? I would like to create a more natural and wildlife-friendly backyard, but I don’t want to break the bank doing it. Are there any tax incentives for completing such projects? Dear EarthTalk: I heard a reference to “Earth-friendly chocolate” and was wondering about what goes into chocolate that would raise environmental concerns. Dear EarthTalk: What’s a “land trust” and how does it help the environment? Dear EarthTalk: What is the status of sharks around the world? I see occasional stories about sharks attacking humans, but on balance aren’t we a lot more brutal to them then they are to us? Dear EarthTalk: What are some of the best online sources of environmental information? Dear EarthTalk: What is the impact of all the littering that individuals do, largely from their cars and on highways? What can I do to help clean it up? How can we strengthen laws to prevent it? Dear EarthTalk: My uncle worked for over a decade on the top floor of an office building with cell phone towers directly above him. He was recently diagnosed with cancer. Is there any scientific evidence of links between exposure to cell phone tower radiation and cancer? Dear EarthTalk: Is it true that traditional mattresses and bedding can cause environmental and health problems, and if so, what alternatives are out there? Dear EarthTalk: My global warming guilt is starting to catch up with me, and I’ve heard that I can buy “carbon offsets” to help make things right. How do they work? Dear EarthTalk: Where do the leading presidential candidates stand on the issue of climate change and other environmental issues? Dear EarthTalk: Most of us know how to recycle paper, plastic and glass, but how do we find out about recycling the many other items we use that eventually break or die out, such as light bulbs, disposable batteries, portable electronics, and so on? Dear EarthTalk: Green groups don’t seem to discuss human population growth, but I think the biggest issue confronting the planet is the collective demand we put upon it. And what is the difference in impact between population growth in Third World countries, which are poor, against that in the U.S., where we consume and waste so much more? Dear EarthTalk: How much of an effect, if any, does the carbon dioxide in carbonated beverages have on global warming? Dear EarthTalk: My New Year’s Resolution is to reduce my “carbon footprint” to help fight global warming. Do you have suggestions for ways I can make good on my promise? Dear EarthTalk: I can’t understand why it is not mandatory to recycle in the U.S. In my home we recycle 80 percent and toss 20 percent and I am trying to improve those percentages. What needs to happen to make recycling the law of the land? Dear EarthTalk: We just started an environmental club at our high school. What issues and activities do you recommend we get involved with to make the most difference? Dear EarthTalk: My condo kitchen floor is vinyl, installed back in 1979. I am told the vinyl contains asbestos. Now it needs replacing. How do I safely remove the vinyl and what are some green choices for a new floor? Dear EarthTalk: I’m looking for a job and would like to find a position at a company that is either marketing a green product or service or that is seriously trying to improve its ecological “footprint.” Where do I look? Dear EarthTalk: Why aren’t compact fluorescent light bulbs taking over more quickly from incandescents, given their substantial energy-saving advantage? And what about recycling them when they ultimately burn out? I’ve heard they contain mercury. Dear EarthTalk: Many foods like tuna and pet foods that formerly were sold only in cans are now available in “pouches” as well. Is this kind of packaging less harmful to the environment or just cheaper to make for the seller? Dear EarthTalk: I’m in the market for new furniture. What should I look for in natural furniture and where do I find it? Dear EarthTalk: Where does all the medical waste from labs, doctor’s offices and hospitals go? Does it just get put in a barrel and buried? Do they dump it in the oceans? With all the waste that is probably generated, it would be interesting to know where all those vials of blood and stuff go. Dear EarthTalk: The impacts of all the paving that is done for new roads and parking lots must be considerable. Other than Joni Mitchell’s “They paved paradise and put up a parking lot” issue, what else is this activity doing that will come back to haunt us? Dear EarthTalk: I have been alarmed at recent news about dangerous substances in kids’ toys shipped to the U.S. from China, though I doubt that such concerns are limited to Chinese products. What are the major issues associated with chemicals in child toys? Dear EarthTalk: What are the best sources out there for environmentally friendly consumer products? I don’t want to have to drive all over creation for green laundry and other cleaning products or to find carpets, bedding and other necessities that won’t bring chemicals into my home. Dear EarthTalk: We’ve all seen the current generation of hybrid cars, but what vehicles do the automakers have coming out that are even greener? Dear EarthTalk: I recently had an argument with a friend who says that if we pollute and cut down the forests, it doesn’t matter because the Earth will take care of itself anyway. How would you counter such an argument? Dear EarthTalk: I would think that the glossy paper used by most magazines is bad for the environment, yet most publishers still use it, even the outdoors and environmental titles. What’s the scoop? Is paper made glossy by using chemicals that are not safe? Dear EarthTalk: In lieu of federal action in the U.S. to combat global warming, have any states taken local measures to reduce greenhouse gas emissions? Dear EarthTalk: Are the rumors true that refilling and reusing some types of plastic bottles can cause health problems? Dear EarthTalk: Is it true that global warming can exacerbate allergies? Dear EarthTalk: Please help settle the debate about whether or not my cats should stay in or go out. My neighborhood is relatively safe for cats, vis-à-vis car traffic, and I think it is more natural for them to be outside and not always inside. They do kill wildlife, including birds, but aren’t they just taking the place of natural predators that once did the same? Dear EarthTalk: The hospital I work at doesn’t recycle at all, not even plastic bottles and cans or food service trays. I was wondering how to get the facility to start up some kind of recycling system? Dear EarthTalk: I’ve heard about the die-off of coral reefs due to global warming. I’ve also read that coral reefs themselves store carbon dioxide (CO2), one of the main global warming gases. So if coral reefs are dying out, isn’t that a double whammy that increases the CO2 in the atmosphere? Dear EarthTalk: Short of buying a new hybrid or other “green” car, are there ways I can make my existing vehicle more eco-friendly? I bought my car recently and am not quite ready to give it up.

Dear Earth Talk: The soil beneath our feet is a critical resource we often take for granted. But I have heard that there are many threats to soil. What are they and how do we make things right?
Dear Earth Talk: I was surprised to learn recently that some cities, including New York, have outlawed kitchen-sink garbage disposals, at least in homes. I would have thought these machines were Earth-friendly. What’s the deal? Dear Earth Talk: I want to give my baby fresh, organic food but I don't have the time to make her special meals. What options are out there? Dear Earth Talk: What are the ramifications for shorelines around the world if predictions about rising sea levels due to global warming actually come true? Dear Earth Talk: What would be the feasibility of having hybrid cars run on E85 or biodiesel? Wouldn’t this solve multiple problems? Dear Earth Talk: OK, once and for all, which is more environmentally friendly: paper or plastic at the grocery checkout? And didn’t I just hear that San Francisco has banned plastic bags? Dear Earth Talk: What is the issue with the Gulf Stream in relation to global warming? Could it really stop or disappear altogether? If so, what are the ramifications of this?
Dear Earth Talk: What is the status of the land mines issue popularized by Princess Diana and Paul McCartney’s ex-wife, Heather Mills? How many mines have been removed? How many are left? What is being done? Dear Earth Talk: What are the best kinds of dishwasher and laundry soaps to use in consideration of where all the wastewater goes after use? Dear EarthTalk: How is it that flushing cat litter down the toilet has negatively affected sea otters? What is the responsible way to dispose of cats’ waste? Dear EarthTalk: How can we get schools to offer healthier and more eco-friendly cafeteria food to our kids? I don’t have time to bag a healthy lunch every day. Week of 8/5/07 Dear EarthTalk: Aside from the obvious benefits to mankind of reducing poverty, how would promoting more economic equality around the world benefit the environment? Week of 7/29/07 Dear EarthTalk: I am considering buying Honda’s natural gas Civic. What exactly comes out of a natural gas vehicle’s tailpipe, and how harmful to the environment is natural gas extraction and refinement? Which is greener, a hybrid or natural gas car? Week of 07/22/2007 Dear EarthTalk: What alternatives are there to traditional fertilizers and other chemicals typically used on golf courses? What other actions can be taken to make golf courses kinder to the environment? Week of 07/15/2007 Dear EarthTalk: I visited New York City recently and could not believe the number of taxicabs on the streets. Are there any efforts to “green up” these vehicles? They must be real gas-guzzlers, considering all the idling and stop-and-go traffic they face. Week of 07/08/2007 Dear EarthTalk: I’m moving in eight weeks and am trying to find some “green guidance” for making my relocation as eco-friendly as possible. Any tips? Week of 07/01/2007 Dear EarthTalk: How much pollution do motorcycles generate? Are there efforts to make them more eco-friendly? Week of 06/24/2007 Dear EarthTalk: Why do some people complain about fluoride in drinking water and toothpaste? I thought it was beneficial for dental health?

Week of 05/13/07 Dear EarthTalk: Are there organizations that specifically address the environmental challenges faced by poor and minority communities? Week of 05/06/2007 Dear EarthTalk: Are there nontoxic substitutes for Scotchgard? I just re-covered an antique chair and I want to protect the fabric from spills and dog paws. Week of 04/29/2007 Dear EarthTalk: Did Exxon/Mobil really pay scientists and economists to write articles trying to de-bunk global warming? Week of 04/22/2007 Dear EarthTalk: What’s the deal with rBGH, the hormone given to cows that makes them produce more milk? Why do some groups want it banned? Week of 04/15/2007 Dear EarthTalk: I see so much waste in packaging every day--from water in self-serve bottles to all the foil and cardboard you have to break through to get to a new print cartridge. What is being done to make packaging more “green friendly,” including cutting out as much of it as possible? Week of 04/08/2007 Dear EarthTalk: Every time I visit my local print shop, I am overwhelmed by the smell of chemicals, and wonder if the health of the workers there is affected.

What innovations are coming down the pike that will bring costs down to make solar competitive with other energy sources? Week of 03/04/2007 Dear EarthTalk: Have “green” or “socially responsible” investments performed better or worse than the rest of the stock market in recent years?

Week of 02/11/2007 Dear EarthTalk: Dairy products like yogurt always seem to come in packages of low recyclabilty (labeled “5,” which our town won’t take). Why aren’t these containers more recyclable? And isn’t there a more eco-friendly container these companies could use? Week of 02/04/2007 Dear EarthTalk: What is an “urban heat island” and does it have anything to do with global warming?
