Mankind has probably done more damage to the Earth in the 20th century than in all of previous human history.

I am not a scientist. I am, rather, an impresario of scientists.

To restate an old law - when a man bites a fish, that's good, but when a fish bites a man, that's bad. This is one way of saying it's all right if man kills an animal, but if an animal attacks man, the act is reprehensible.

How dangerous are those sea animals with bad reputations? A few actually kill. A few maim. Some are poisonous when eaten by man. Most sting, stab,or poison and cause mild to severe discomfort to man. Yet man is one of the larger beings that sea creatures encounter, and these poisons usually can't kill him.

A common denominator in every single nuclear accident - a nuclear plant or on a nuclear submarine - is that before the specialists even know what has happened, they rush to the media saying, 'There's no danger to the public.' They do this before they themselves know what has happened because they are terrified that the public might react violently, either by panic or by revolt.

We must alert and organise the world's people to pressure world leaders to take specific steps to solve the two root causes of our environmental crises - exploding population growth and wasteful consumption of irreplaceable resources. Overconsumption and overpopulation underlie every environmental problem we face today.

When we return wild animals to nature, we merely return them to what is already theirs. For man cannot give wild animals freedom, they can only take it away.
