Striking a balance between wildlife conservation and wind energy development starts with understanding threats to eagle populations and how our actions, including operating wind farms, are affecting them.

All Americans have benefited from the dedicated service of Representative Henry Waxman. In every battle and in every moment that mattered most, Rep. Waxman stood up for the air we breathe, the water we drink, and the wild places we cherish.

Under pressure from a growing movement of people who want their money out of fossil fuels, universities, pension investors and foundations are looking to exclude coal, oil and gas stocks from their portfolios.

For decades, NRDC has created and supported policies that will ultimately end our reliance on fossil fuels.

We look back at the 1990 Clean Air Act amendments, where people screamed and hollered it's going to be too expensive, they couldn't afford it, and it wouldn't work. And it worked. It worked faster than people expected, at much less cost.

A stock market index helps investors track the performance of a group of stocks. NRDC worked with FTSE to develop comprehensive and transparent methodologies that screen out companies linked to owning, exploring, or extracting fossil fuels.

The San Gabriel Mountains rise like a rampart at the edge of the city, safeguarding more than 500,000 acres of mature forests, mountain streams, dramatic waterfalls, and towering peaks that reach over 9,000 feet. These untamed places attract bighorn sheep, mountain lions, and other threatened or endangered species.

Every year, tens of millions of salmon return to the pristine shores of Bristol Bay in Alaska. They linger in the bay's cool, shallow waters before charging up nearby streams to spawn and create another generation of wild salmon.

Protecting eagles from the threat of extinction is a conservation success story that we must prudently safeguard for future generations to come.

The science tells us that if we fail to reduce global warming pollution, global temperatures will rise to dangerous levels and unleash devastating extreme weather events and accelerate destructive sea level rise.

I was in college when tens of thousands of people marched on Washington for the first Earth Day. Raw sewage floated in rivers and clouds of smog hung over cities. But then something amazing happened. People spoke out. Thousands of students, workers, and ordinary citizens used their voices to say, 'This has to change.'

The Keystone XL pipeline is a threat to our nation. It would increase pollution and intensify climate change for generations to come. We must raise our voices and demand our leaders reject this dirty scheme.

From reinforcing beaches in the Rockaways to installing generators at the Coney Island Houses and sealing holes in the subway system, New York is fortifying our ability to withstand future storm surges.

I do believe that the coal industry sees the cultural shift toward cleaner energy and global warming solutions as a threat to their interests.

Getting toxic lead out of gasoline, the oil industry shouted, would cost a dollar a gallon. It turned out to cost just a penny a gallon to protect hundreds of thousands of kids from lead-induced brain damage.

The signs of climate change are visible across the nation, from the drought-stricken fields of Central California to the flooded streets of Michigan. Extreme weather is turning people's lives upside down and costing communities millions of dollars in damaged infrastructure and added health care costs.

Many environmental battles are won by delaying a destructive project long enough to change the conversation - to allow new economic, political and social dynamics to emerge.

Mercury is most commonly recognized as a developmental toxin, threatening to young children and fetuses as they develop their nervous system. Prenatal exposure to even low levels of mercury can cause life-long problems with language skills, fine motor function, and the ability to pay attention.

Safer chemicals and more energy-efficient technologies can provide cooling without severe climate implications. Shifting to these alternatives could avoid the equivalent of 12 times the current annual carbon pollution of the United States by 2050.

Carbon pollution contributes to climate change, which causes temperatures to rise. Hotter temperatures mean more smog in the air, and breathing smog can inflame deep lung tissue. Repeated inflammation over time can permanently scar lung tissue, even in low concentrations.

Opening up Atlantic and Arctic waters to drilling would lock the next generation into burning oil and gas in a way that only makes climate change that much worse, fueling ever rising seas, widening deserts, withering drought, blistering heat, raging storms, wildfires, floods and other hallmarks of climate chaos.

Shell has poured billions of dollars into offshore Arctic drilling, but no matter how much it spends, it cannot make the effort anything but a terrifying gamble. And if Shell, the most profitable company on Earth, can't buy its way to safety in Alaska, nobody can.

When we go to the store, we bring home more than food - we bring home traces of broader environmental problems. But we can use our shopping carts and dinner plates to help solve some of those problems.

Wind and other clean, renewable energy will help end our reliance on fossil fuels and combat the severe threat that climate change poses to humans and wildlife alike.
