I have voted against only one of President Obama's nominees: Michael Froman, a Citigroup alumnus who is currently storming the halls of Congress as U.S. Trade Representative pushing trade deals that threaten to undermine financial regulation, workers' rights, and environmental protections.

The BP spill was the greatest environmental catastrophe in U.S. history. Yet somehow, gas companies like BP and Halliburton ran interference on reporting that story.

What is true environmentalism? I think it's environmental stewardship - not prohibition.

This is absolutely bizarre that we continue to subsidize highways beyond the gasoline tax, airlines, and we don't subsidize, we don't want to subsidize a national rail system that has environmental impact.

I align myself with almost all researchers in assuming that anything we do is a composite of whatever genetic limitations were given to us by our parents and whatever kinds of environmental opportunities are available.

I think the government has to reposition environment on top of their national and international priorities.

Yet, despite our many advances, our environment is still threatened by a range of problems, including global climate change, energy dependence on unsustainable fossil fuels, and loss of biodiversity.

With increasing fervor since the 1980s, sustainability has been the watchword of scientists, environmental activists, and indeed all those concerned about the complex, fragile systems on the sphere we inhabit. It has shaped debates about business, design, and our lifestyles.

Moreover, the practical recommendations deduced from ecological principles threaten the vested interests of commerce; it is hardly surprising that the financial and political power created by these investments should be used sometimes to suppress environmental impact studies.

I do comparative studies of climate evolution, and the interactions between planetary atmosphere and surfaces and their radiation environment, and try to understand the environmental factors that can affect a planet's habitability and how they change over time.

We had a great chance in the mid-2000s to reach an accord with the Chinese on both energy and environmental issues. That deal would have essentially been that the U.S. could provide the equipment and expertise, and the Chinese would help close the trade gap. It was a huge opportunity that we failed to exploit.

Fossil fuels will run out not because of limited resources but because of the environmental impact. If I can solve that impact, I have basically increased the resource base by a vast amount.

A very Faustian choice is upon us: whether to accept our corrosive and risky behavior as the unavoidable price of population and economic growth, or to take stock of ourselves and search for a new environmental ethic.

More and more companies are reaching out to their suppliers and contractors to work jointly on issues of sustainability, environmental responsibility, ethics, and compliance.

The environmental effects of the automobile are well known: motor vehicles cause, for example, as much as 75 percent of the noise and 80 percent of the air pollution in our cities, and the industry must face mounting pressure from environmentalists.

We must move away from our dependency on fossil fuels, and I am glad that GM has invested over $1 billion in hydrogen fuel cells cars to meet this goal.

From year to year, environmental changes are incremental and often barely register in our lives, but from evolutionary or geological perspectives, what is happening is explosive change.

Journey with me to a true commitment to our environment. Journey with me to the serenity of leaving to our children a planet in equilibrium.

I'm anti-tax, but I'm pro-carbon tax.

As you heat the planet up, it's just like boiling a pot.

I have a huge fan following in Bellary, and when they met me, they told me about their problems. I have seen mining done without proper safety measures and not taking environmental protection into account.

We learned that economic growth and environmental protection can and should go hand in hand.

I have a private plane. But I fly commercial when I go to environmental conferences.

Factory farming is one of the biggest contributors to the most serious environmental problems. The meat industry causes more greenhouse gas emissions than all the cars, trucks, planes and ships in the world.

The Endangered Species Act is the strongest and most effective tool we have to repair the environmental harm that is causing a species to decline.

Practically every environmental problem we have can be traced to our addiction to fossil fuels, primarily oil.

I try to understand place on a deeper level than just the physical or environmental aspects. It includes cultural and intellectual forces, too. It's an inclusive approach that brings in many disciplines and sees place as a dynamic thing.

The world faces enormous human development and environmental challenges, from poverty and disease to food security and climate change.

I see humanity now as one vast plant, needing for its highest fulfillment only love, the natural blessings of the great outdoors, and intelligent crossing and selection.

Environmental policy must strike a balance between the earth's best interests and our citizen's pressing needs.

Clinton understands that climate change is real, is caused by human activity and is one of the great environmental crises facing our planet. She knows that we must transform our energy system away from fossil fuels and move aggressively to energy efficiency and sustainable energy.

We have a project with Unocal here in Los Angeles, where we as an environmental organization, the oil company, and the state all get together to promote the recycling of used motor oil.

You may be able to fool the voters, but not the atmosphere.

I do believe very strongly that all of us and all of the other things in the context of our planet with Mother Nature, all of these things absolutely have a profound effect.

Though dams and artificial lakes can have significant negative environmental impacts, when carefully considered, mitigated, and managed, the benefits of hydropower often outweigh these costs.

No one is an environmentalist by birth. It is only your path, your life, your travels that awaken you.

Environmental activists in the rough Antarctic seas have launched a new tool in the fight to stop a Japanese operation to kill hundreds of whales: remote-controlled drones.

On April 16, 2010, 34 Chinese environmental organizations, including Friends of Nature, the Institute of Public and Environmental Affairs, and Green Beagle, questioned heavy metal pollution in a letter sent to CEO Steve Jobs.

We firmly believe the environmental issues cannot be addressed without extensive public participation, but people need to be informed before they can get involved.

If you cut down a forest, it doesn't matter how many sawmills you have if there are no more trees.

Without the oceans there would be no life on Earth.

The most important environmental issue is one that is rarely mentioned, and that is the lack of a conservation ethic in our culture.

All our environmental problems become easier to solve with fewer people and harder - and ultimately impossible to solve - with ever more people.

The environmental problems of developing countries are not the side effects of excessive industrialisation but reflect the inadequacy of development.

In Kenya women are the first victims of environmental degradation, because they are the ones who walk for hours looking for water, who fetch firewood, who provide food for their families.

I have American in-laws, and I care about the environment. We don't use disposable diapers, which, of course, creates an environmental problem of our own.

I think so long as fossil fuels are cheap, people will use them and it will postpone a movement towards new technologies.

I've been active in animal rights and all kinds of environmental stuff and children's charities over the years.

I tell my environmental friends that they have won. Every issue we look at from an energy perspective is now also looked at from an environmental perspective.

The growth that we want is one that brings real benefits to the people, raises quality and efficiency of development, and contributes to energy conservation and environmental protection.
