That People Will Object Very Much To

Anyone Who Thinks That You Can Have Infinite Growth On A Planet With Finite Resources Is Either A Madman Or An Economist.

The Climate, The Economic Situation, Rising Birth Rates; None Of These Things Give Me A Lot Of Hope Or Reason To Be Optimistic.

I Like Animals. I Like Natural History. The Travel Bit Is Not The Important Bit. The Travel Bit Is What You Have To Do In Order To Go And Look At Animals.

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?

It Is That Range Of Biodiversity That We Must Care For - The Whole Thing - Rather Than Just One Or Two Stars.
