Florida will be gone altogether, the whole damned place, in not too long.

You mustn't take what I say as gospel because no one can second-guess the future.

Nature favors those organisms which leave the environment in better shape for their progeny to survive.

For each of our actions there are only consequences.

Those who fail to see that population growth and climate change are two sides of the same coin are either ignorant or hiding from the truth. These two huge environmental problems are inseparable and to discuss one while ignoring the other is irrational.

The problem is we don't know what the climate is doing. We thought we knew 20 years ago. That led to some alarmist books - mine included - because it looked clear-cut, but it hasn't happened.

Our future is like that of the passengers on a small pleasure boat sailing quietly above the Niagara Falls, not knowing that the engines are about to fail.
