Dear EarthTalk: I was appalled by the pollution haze I saw on a recent visit to Acadia National Park in Maine, and was told by a ranger that it was from smokestacks and tailpipes hundreds of miles away. Is anything being done to clear the air in Acadia and other natural areas where people go to breathe fresh air and enjoy distant unobstructed views?
Has an alternative to AC to keep rooms cool been invented that is significantly cheaper and/or that uses significantly less energy than traditional air conditioning?
Dear EarthTalk: Why were some environmental websites blacked out all day back on June 4? Was this some sort of protest, or did they get hacked?
Dear EarthTalk: We’ve been hearing for years how producing red meat is bad for the environment while consuming it is bad for our health. How do other types of meat, fish, dairy and vegetable proteins stack up in terms of environmental and health impacts?
Dear EarthTalk: How are the world’s reptile species faring in terms of population numbers and endangered status? What’s being done, if anything, to help them?
Dear EarthTalk: What’s the deal with New York City buildings switching over from heating oil to natural gas? Is this a trend in other U.S. cities as well?

Dear EarthTalk: I recently saw an article extolling the virtues of natural gas as an abundant, inexpensive and domestically produced automotive fuel. Is this going to be the automotive fuel of the future and how green is it?
Dear EarthTalk: Renewable energy production in the solar and wind markets currently receives about $7 billion in government subsidies annually, but is still not competitive against fossil fuels on a large scale. To what extent should the U.S. continue to prop up these industries as they compete against dirty energy?
Dear EarthTalk: Who are the “Clean Air Ambassadors” and what are they trying to accomplish?
