Loads of chemicals and hazardous wastes have been introduced into the atmosphere that didn't even exist in 1948. The environmental condition of the planet is far worse than it was 42 years ago.

Our goal is not just an environment of clean air and water and scenic beauty. The objective is an environment of decency, quality and mutual respect for all other human beings and all other living creatures.

We're going to have to do a whole lot more, and give nature at least a chance to repair some of the damage we've done.

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.'

In the state of Wisconsin it's mandated that teachers in the social sciences and hard sciences have to start giving environmental education by the first grade, through high school

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?

Every person has the inalienable right to a decent environment.
