We've made some heroic efforts, but the Earth as a whole is in worse shape today than 30 years ago, ... There's been 30 more years of greenhouses gases, species extinctions and population growth.

There was almost a universal acceptance of unhealthy conditions. Sulfur dioxide in smokestack emissions were the price, or smell, of prosperity.

Listen up, you couch potatoes: each recycled beer can saves enough electricity to run a television for three hours.

I feel more confident than ever that the power to save the planet rests with the individual consumer.

By the year 2000, such renewable energy sources could provide 40 percent of the global energy budget; by 2025, humanity could obtain 75 percent of its energy from solar resources.

When civilization stands at the edge of a cliff, a step forward doesn't make much sense.

It is already too late to avoid mass starvation.

We presently have the technology ... fuel cells, solar cells, hydrogen ... the opportunities are amazing for clean energy.

These are not exhortations from overwrought extremists, but carefully phrased warnings from some of the world's finest scientists.

To top it off, for those of you who are interested in the economics, it costs more to pursue a capital case toward execution than it does to have full life imprisonment without parole.
