Just as there's garbage that pollutes the Potomac river, there is garbage polluting our culture. We need an Environmental Protection Agency to clean it up.

To deal with these problems - of world population and hunger, of peace, of energy and mineral resources, of environmental pollution, of poverty - we must broaden and deepen our knowledge of nature's laws, and we must broaden and deepen our understanding of the laws of human behavior.

The majority of autists - as well as their parents - seem to be genuine victims of environmental stress.

Unless action is taken soon - unless we can display the same vision of that earlier period - we will lose the treasure of California's open space and environmental beauty.

I'd say that animal rights and environmental issues have always been at the forefront of my mind.

The worst environmental decision you can make as a human being is to have 14 kids.

Wouldn't it help Americans more, in the long run, if we were forced to accept some responsibility for the environmental wreckage we prefer to assume is totally out of our control?

Every decision we make - when we choose a vehicle, when we pump gas into that vehicle, when we order food - is not just a personal lifestyle choice. It's an environmental and moral choice.

Businesses can lead with their values and make money, too. You don't have to simply be purely profit-driven. You can integrate social and environmental concerns into a business, be a caring business, be a generous business and still do very well financially.

Businesses typically look at issues like price, quality, time of delivery. They don't often think about social and environmental impact because they're focused on their financial bottom line.

Look at your business and the activities that you undertake. Then, start to think about not just your economic concerns, but about social and environmental impacts that businesses have.

The main environmental challenge of the 21st century is poverty. When you don't know where your next meal is coming from, it's hard to consider the environment 100 years down the line.

These days, most nature photographers are deeply committed to the environmental message.

On almost every environmental issue I care about, in fact, I've been wrong at one point or another. I used to think that climate change was no big deal, that most environmental problems were massive exaggerations, that oil reserves were effectively unlimited, and more.

Threats that could wipe out the bulk of life on earth abound. Planetary catastrophe could come in the form of a killer asteroid impact, the eruption of massive supervolcanoes, a nearby gamma ray burst that sterilizes the earth, or by human-driven environmental collapse.

Environmental concern is a phenomena that tends to rise in a nation after a certain level of wealth.

Producing food to eat is the single most destructive environmental activity humans engage in.

Why should we not expect self-designated environmental leaders to practice what they preach?

I'm a latecomer to the environmental issue, which for years seemed to me like an excuse for more government regulation. But I can see that in rich societies, voters are paying less attention to economic issues and more to issues of the spirit, including the environment.

If you look at the history of other movements, whether Civil Rights or environmental rights, these are all decades-long undertakings.

Not all is doom and gloom. We are beginning to understand the natural world and are gaining a reverence for life - all life.

You don't have to live in the country and grow your own food to be green.

In today's world, it is no longer unimaginable to think that business can operate - and even thrive - in an environmentally-friendly manner.

If we talk about the environment, for example, we have to talk about environmental racism - about the fact that kids in South Central Los Angeles have a third of the lung capacity of kids in Santa Monica.

I was surprised to see how much the mainstream environmental movement hates the ELF.

I have a pretty positive view of environmental activism, but I didn't know much about the ELF. A lot of people make documentaries because they have something they want to say, but I make them because there's something I want to explore.

All too often, the conversation about appropriate and balanced environmental stewardship gets caught up in partisan politics. Yet, this conversation is key to the preservation of our great country for generations to come, as important as ensuring we have fiscally responsible policies to secure our future.

I believe very strongly that corporations could and should be a major force for resolving social and environmental concerns in the twenty-first century.

There's a rising tide of environmental awareness and activism among consumers that's going to continue to swell in the 21st century. Smart companies will get ahead of that wave and ride it to success and prosperity. Those that don't are headed for a wipeout.

I assume we will have figured out a way to efficiently utilize solar energy and tied that to an efficient way to use nuclear energy in such a way that it doesn't pose a serious environmental issue.

We don't want the federal government coming in and telling us how to do our environmental remediation or how we're going to do our healthcare.

Even as we continue to carry the banner of civil rights and environmental justice, we've also got to focus on many, many people - for them, life starts with a good job.

Business has a way of talking about how to create value, which is in some way isn't bad... We just need to start thinking about if the value we want to create is consistent with all social and environmental well being.

Lady Bird Johnson did more than plant flowers in public places. She served the country superbly by planting environmental values in the minds of the nation's leaders and citizens.

The motivation should come from regulatory enforcement, but enforcement is weak, and environmental litigation is near to impossible. So there's an urgent need for extensive public participation to generate another kind of motivation.

We copied laws and regulations from western countries, but enforcement remains weak, and environmental litigation is still quite near impossible.

Brands who come to China, often they just care about price - so they actually drive the suppliers to cut corners on environmental standards to win a contract.

China has leapfrogged into this information age, and Web users have grown very significantly, which knocked down the cost of doing the environmental transparency.

In America, you complain about job losses because of China, but here, we carry all of the environmental costs.

Environmental problems cannot be resolved here the way they are resolved in other countries. I heard that 80 per cent of the environmental problems in the U.S. are solved in court. That can't happen here.

China leads the world in energy consumption, carbon emissions, and the release of major air and water pollutants, and the environmental impact is felt both regionally and globally.

It has been shown that public participation can limit powerful interest groups, while competing interests can help find a reasonable balance between development and environmental protection.

China's environmental conundrums will not be solved by changes within government alone. New mechanisms are needed to allow the communities which may be affected by a given plan, and citizens concerned about the environment, to join in.

Environmental agencies in China are hamstrung by local officials who put economic growth ahead of environmental protection; even the courts are beholden to local officials, and they are not open to environmental litigation.

We must strictly enforce the Environmental Law, closing down the polluters that fail to meet the standards.

China is bearing the environmental cost for much of the world because China is the factory of the world.

Urban residents, most of them middle class, have a much better sense of their environmental rights, and they're willing to take to the streets.

I've always been a strong supporter of environmental protection and initiatives in that area. But I'm willing to set priorities. If we have to make reductions in one place, we'll have to-in order to increase another place, I'm willing to do that.

The environment has fallen to the wayside in politics.

I think future engineered species could be the source of food, hopefully a source of energy, environmental remediation and perhaps replacing the petrochemical industry.
