The conservative movement's pro-fossil fuel advocacy flies in the face of free-market economics. Why are we continuing to subsidize highly profitable and polluting fossil fuel firms while choking off support for clean energy? We are not supposed to be the fossil fuel industry's trade union.

President, League of Conservation Voters

Our chemical regulatory system is broken. Our nation's primary chemical law -- the Toxic Substances Control Act (TSCA) -- was passed in 1976. Over the years, it's become outdated and is now so flawed that many chemicals, including the one involved in this spill, go virtually unregulated.

Michael Brune

Executive Director, The Sierra Club

every time I hear President Obama or someone in his administration talk about an "all of the above" energy policy, it's like fingernails on a solar panel. If someone asked you which way leads to the top of a mountain, would you tell them "all of the above"? Of course not.

No army can win a war without good quality water. Dysentery took more lives in the U.S. Civil War than battle wounds. Likewise, the War on Poverty won't be won without healthy and affordable water.

The usual explanation is that, for these voters, economic issues are trumped by social and cultural issues like guns, abortion, and race. I'm not so sure.

When my aunt goes out to buy freshly-made croissants, I didn't sniff them and ask, with disdain, if they are organic. I eat a freakin' croissant because she bought them for me out of love.

Broadcaster, Conservation Biologist, Educator

My recent passionate broadcast across Australia on the 'War Against Nature' elicited many emails especially from children. They all wanted to know: "Why are adults killing nature?"

The retort appears to be the Indian government's stock response to concerns that its planned expansion of coal mining is so immense that it could render extinct the tiger population of central India.

We are tricking ourselves into using cheap and easy oil as fast as we can pump it out of the ground. And perhaps the most pernicious cost of oil is that it has fueled an unprecedented degradation of the global biosphere.

Senior Scientist at Pesticide Action Network

USDA welcomed in the new year by presenting Dow AgroSciences with a bountiful gift: a virtual green light for the pesticide company's new genetically engineered (GE) corn and soybean seeds. These crops are designed specifically to be used with Dow's infamous herbicide, 2,4-D.

Representatives of Entergy Nuclear and the union representing control room operators and other technical workers are preparing for around the clock bargaining sessions to avoid a strike at the two Indian Point nuclear plants.

We are as much helpless victims of climate change as the Pacific Islands are only holiday destinations. The truth is we are not drowning; we are fighting.

Eddie Parsons

The end of summer brought the public declaration that I was going to open myself up to dog ownership and curious minds asked a ton of unsolicited questions.

Professor of Chemistry, York College

It's a tough life for an Olive Ridley Turtle. We can thank the conservationists and volunteers at Montezuma for making life just a bit easier.

CEO, American Wind Energy Association

This long-awaited program will provide more eagle conservation than currently exists today, which leaves many in the wind industry and others who share our concern for saving eagles scratching our heads over the hyperbolic response.

Arianna Huffington

Animals help us be better humans. Quite often, they show us how to be our best selves. Always in the moment, sticking their noses into everything (literally), they see a world that we take for granted, one we're usually just hurriedly passing through on our way to lives we never quite reach.

It's ironic that understanding these signals is absolutely crucial for dog owners, and yet they're not commonly taught or discussed. In a situation such as the beagle-baby one, had the owner's mind not been put at ease, the dog might have lost his home.
