All economic activity is dependent upon that environment and its underlying resource base of forests, water, air, soil, and minerals. When the environment is finally forced to file for bankruptcy because its resource base has been polluted, degraded, dissipated, and irretrievably compromised, the economy goes into bankruptcy with it.

I think the internal combustion engine will disappear from the streets of our cities in the next thirty years because transportation will be mass transportation, or probably electrical power.

If we continue to address the issue of the environment where we live as though we're the only species that lives here, we'll create a disaster for ourselves

It was truly an astonishing grassroots explosion, ... The objective was to get a nationwide demonstration of concern for the environment so large that it would shake the political establishment out of its lethargy.

Dr. S. Dillon Ripley, secretary of the Smithsonian Institute, believes that in 25 years, somewhere between 75 and 80 percent of all the species of living animals will be extinct.

The bigger the population gets, the more serious the problems become... We have to address the population issue. The United Nations, with the U.S. supporting it, took the position in Cairo in 1994 that every country was responsible for stabilizing its own population. It can be done. But in this country, it's phony to say 'I'm for the environment but not for limiting immigration.'

As far as I know, most organizations are avoiding population issues because they're politically frightened by the charge that comes from some proponents of immigration that if you oppose the immigration policy we have now, you're a racist.. There is no way in the world we can forge a sustainable society without stabilizing the population. ... There's no practical way of stabilizing the population of the U.S. without reducing the immigration rate. When do we decide we have to do something, or do we wait until things are as bad here as they are in the countries people want to leave?
