* Is there really such a thing as “sun-protective clothing?” If so, does it mean I can dispense with oily sunscreens once and for all?

Global Warming - Truth or Fiction?
I keep meeting people who say that human-induced global warming is only theory, that just as many scientists doubt it as believe it. Can you settle the score?

Urban Wind Turbines
A fan of Buckminster Fuller, Professor Bill Becker decided there must be a better way to design wind turbines; one that would allow them to be used in urban environments where the wind is erratic and dangerous.

Can Compact Flourescent Bulbs Cause Headaches?
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.

Autism and the Environment
What’s going on with all the cases of autism cropping up and no one seems to know why? It stands to reason it must be something (or some things) environmental, yet every study allegedly turns up no conclusion...

Water Conservation Tips in a Drought
It's easy to take for granted a resource that is abundantly available in our daily lives. But the ease with which we can access this vital commodity often obscures the reality that it is in fact a limited resource.

China's Olympics Going Green
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?

Bottled Water Backlash
Bottled water is out, and tap water is in, says the May/June 2008 cover story of E – The Environmental Magazine (now posted at: www.emagazine.com). Call it reverse snob appeal. These days, it’s the tap water enthusiasts, concerned about the environment, who get to act self-righteous. Just like it has become cool to bring your own cloth bags to the grocery store and your own mug to the coffee shop, the reusable water bottle is the hip, new eco-accessory.

Turn Out Your Lights Tonight For Earth Hour
Participate in Earth Hour on March 29th, 2008 by turning off your lights for one hour from 8PM to 9PM. When this took place in Sidney, Australia in 2007 the reduction in greenhouse gases was equivalent to taking 48,000 cars off the road.

Urban Parrot Colonies
At least three dozen different parrot species are now considered threatened or endangered in their quickly shrinking native tropical and sub-tropical habitats (mostly in South America). As such, the health of wild flocks in the U.S. and other developed countries around the world may well be key to preserving these birds that could otherwise go extinct.

Recycling Old Clothes
The typical U.S. city with 50,000 residents has to pay (with local tax dollars) for the handling and disposal of some 3,000 tons of textiles every year. The shame of such waste is that textiles are so easy to recycle or otherwise find new uses for.

What is the status of sharks around the world?
Humans do a lot more damage to shark populations than vice versa. Marine biologists report that sharks are in rapid decline around the world. In the North Atlantic Ocean, shark populations have declined more than 50 percent over the past 20 years alone, with some species now nearing extinction.

How do Carbon Offsets Work?
Carbon offsets are monies that consumers and businesses pay voluntarily to compensate for the greenhouse gas emissions they generate directly by driving, flying, running the air conditioning and otherwise using non-renewable energy.

How much of an effect, if any, does the carbon dioxide in carbonated beverages have on global warming?
A typical 12-ounce can of soda contains up to six grams (.013 pounds) of carbon dioxide (CO2) gas, which either escapes into the atmosphere from the liquid upon opening, or from your body after you consume the contents. So yes, drinking carbonated beverages does contribute to your “carbon footprint,” but only ever so slightly.

Living Roof Takes the California Academy of Sciences Green
The new California Academy of Sciences is slated to open in October 2008 with an advanced green architecture design featuring an amazing living roof. The entire complex was designed by Renzo Piano with ecology in mind, but the living roof is one of its most intriguing features.

Paper and The Environment
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? -- Kellina H., via e-mail

Water Conservation Tips
When your community is struggling with an extended drought like California has, many communities urge voluntary conservation measures. Many of these conservation campaigns encourage every person to work to save just 20 gallons of water each day.
