I'm Luckier Than My Grandfather,

It Is Curiosity, Quite Right-a Divine Curiosity. A Characteristic Of The Gods Is Curiosity.

Human Beings, Because We're So Clever, Have Removed Every Single One Of Those Population Limiting Factors... So Nothing Controls Our Increase In Numbers Except Our Own Wish. Since I First Started Making Television Programs, The Population Of The World Has Increased Three Times. That's An Extraordinary Notion. Can It Increase Four Times? Can It Increase Five Times? The Earth Is A Finite Size. So A Point Will Eventually Come When We Run Out Of Food, When We Run Out Of Space And When We Will Have Destroyed Most Of The Natural World. So Ought We To Do Something About It Before That Happens?

If My Grandchildren Were To Look At Me And Say, 'you Were Aware Species Were Disappearing And You Did Nothing, You Said Nothing', That I Think Is Culpable. I Don't Know How Much More They Expect Me To Be Doing, I'd Better Ask Them.

You Know, It Is A Terrible Thing To Appear On Television, Because People Think That You Actually Know What You're Talking About.

I Suspect That Happiness Is Not A State But Rather A Transition.
