The Only Way To Save A Rhinoceros

One In Eight Plant Species Face Extinction.

I Would Love To Go And See The Himalayan Mountain Kingdoms. There Are Very Few Left Now. I Would Loved To Have Gone To Tibet And Nepal. And There Are Still Parts Of Central Asia That Are Utterly Unexplored.

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?

The Fundamental Issue Is The Moral Issue.

There Is No Question That Climate Change Is Happening; The Only Arguable Point Is What Part Humans Are Playing In It.
