All we can hope for is that the thing is going to slowly and imperceptibly shift. All I can say is that 50 years ago there were no such thing as environmental policies.

You'll find people where their conditions aren't changing in any way, its rather rare for them to be happy.

It's a moral question about whether we have the right to exterminate species.

You have to steer a course between not appalling people, but at the same time not misleading them.

Natural history is not about producing fables.

I suppose happiness is something one enjoys, but I suspect that happiness is not a state but rather a transition.

Opponents say natural selection is not a theory supported by observation or experiment; that it is not based on fact; and that it cannot be proved. Well, no, you cannot prove the theory to people who won't believe in it any more than you can prove that the Battle of Hastings took place in 1066. However, we know the battle happened then, just as we know the course of evolution on earth unambiguously shows that Darwin was right.
