We Really Need To Kick The Carbon

I Don't Approve Of Sunbathing, And It's Bad For You.

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's A Moral Question About Whether We Have The Right To Exterminate Species.

I'm Not A Propagandist, I'm Not A Polemicist; My Primary Interest Is Just Looking At And Trying To Understand How Animals Work.

If I Can Bicycle, I Bicycle.
