Civilization has given us enormous successes: going to the moon technology. But then this is the civilisation that took us to debt environmental crisis every single crisis. We need a civilization where we say goodbye to these things.

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.

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

Ted Turner is still a leader. And he sets a great example. His ability financially has been reduced but his influence and his example still is an important asset to the whole environmental movement.

One of the things that I've always thought I would like to do is to develop an environmental index. Then people can measure their own environmental performance on an index as they do in other ways.

I've developed a huge regard for Toyota for its environmental awareness for its immense commitment to research and development in this field and for its leadership in developing hybrids which others are now following.

I am on the board of corporations who contribute both to environmental problems and their solutions. And I am on the NGO side: the Earth Council and other organizations.

A shift is necessary toward lifestyles less geared to environmental damaging consumption patterns.

At every turn when humanity is asked the question 'Do you want temporary economic gain or long-term environmental loss which one do you prefer ' we invariably choose the money.

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

The industrial processes in use today were developed at a time when no one had to consider what the environmental impact was. Who cared? But making ecological concerns matter to a company's bottom line will help it do the research and development that will reinvent everything we buy.

The position I took at the time was that we hadn't really examined any of the potential environmental consequences of introducing genetically modified organisms.

In this country the health concerns and the environmental concerns are as deep as in Europe. All the surveys show that. But here we didn't have the cultural dimension. This is a fast-food culture.

Have we failed to slow global warming pollution in part because climate and environmental activists have been too polite and well behaved?

Mark Ruffalo aka the Incredible Hulk is the natural gas industry's worst nightmare: a serious committed activist who is determined to use his star power as a superhero in the hottest movie of the moment to draw attention the environmental and public health risks of fracking.

Americans don't pay much attention to environmental issues because they aren't sexy. I mean cleaning up coal plants and reining in outlaw frackers is hugely important work but it doesn't get anybody's pulse racing.

I really believe in the environmental movement right now - it only takes a little effort to make a big difference.

The most meaningful engine of change powerful enough to confront corporate power may be not so much environmental quality as the economic development and growth associated with the effort to improve it.

The environmental crisis arises from a fundamental fault: our systems of production - in industry agriculture energy and transportation - essential as they are make people sick and die.

We need to accept the seemingly obvious fact that a toxic environment can make people sick and that no amount of medical intervention can protect us. The health care community must become a powerful political lobby for environmental policy and legislation.

I am going to confront the old-fashioned negative thinking which says that all government needs to do to generate growth is cut worker and environmental protections cut taxes on the rich and stroke 'fat cats' until they purr with pleasure. I'm completely repudiating the idea that government has to get out of the way.

We have fought for social justice. We have fought for economic justice. We have fought for environmental justice. We have fought for criminal justice. Now we must add a new fight - the fight for electoral justice.

American culture is torn between our long romance with violence and our terror of the devastation wrought by war and crime and environmental havoc.

If China is helping its domestic industries charge an artificially low price for solar panels and other environmental goods then China is violating international trade rules that it agreed to when it became a member of the World Trade Organization.
