“We know that he has stored secret supplies of biological and chemical weapons throughout his country.”

When it comes to climate, we can all make a big difference.

Civil disobedience has an honourable history, and when the urgency and moral clarity cross a certain threshold, then I think that civil disobedience is quite understandable, and it has a role to play.

The will to act is a renewable resource.

The struggle to save the global environment is in one way much more difficult than the struggle to vanquish Hitler, for this time the war is with ourselves. We are the enemy, just as we have only ourselves as allies.

We can believe in the future and work to achieve it and preserve it, or we can whirl blindly on, behaving as if one day there will be no children to inherit our legacy. The choice is ours; the earth is in balance.

Consider what kind of car you get. Buy cars and other products that have the least impact environmentally.

I have always been fascinated with those who try to look over the horizon and see things that are coming at us.

The good news is, we have everything we need now to respond to the challenge of global warming. We have all the technologies we need, more are being developed…. But we should not wait, we cannot wait, we must not wait.

Our world faces a true planetary emergency. I know the phrase sounds shrill, and I know it’s a challenge to the moral imagination.

A zebra does not change its spots.

In a time of darkness, you don’t curse the darkness, you light a candle.

At some point, a false belief collides with physical reality.

We are running out of time, we must have a planetary solution to a planetary crisis.

I strongly believe in the separation of church and state. But freedom of religion does not mean freedom from religion, there is a better way.

The planet is in distress and all of the attention is on Paris Hilton.

Botany is based on fixed genera.

The muscles used to make a smile actually send a biochemical message to our nervous system that it is safe to relax the flight of freeze response.

It now seems very likely that many of the 64 triplets, possibly most of them, may code one amino acid or another, and that in general several distinct triplets may code one amino acid.

Protein synthesis is a central problem for the whole of biology, and that it is in all probability closely related to gene action.

We are all connected; To each other, biologically. To the earth, chemically. To the rest of the universe atomically.

The brain is the last and grandest biological frontier, the most complex thing we have yet discovered in our universe. It contains hundreds of billions of cells interlinked through trillions of connections. The brain boggles the mind.

I turned against the left wing because they don’t like genetics, because genetics implies that sometimes in life we fail because we have bad genes. They want all failure in life to be due to the evil system.

The ultimate aim of the modern movement in biology is in fact to explain all biology in terms of physics and chemistry.
