This is now our planet, run by humankind for humankind. There is little left for the rest of the living world. - David Attenborough

We have overfished 30% of fish stocks to critical levels. We cut down over 15 billion trees each year. By damming, polluting, and over-extracting rivers and lakes, we've reduced the size of freshwater populations by over 80%.

People who accuse us of putting in too much violence, [should see] what we leave on the cutting-room floor. My conscience troubles me more about reducing the pain and savagery that there is in the natural world than the reverse.

I was born into a world of just under two billion people today there are nearly seven billion of us. Whenever I hear those numbers I can honestly say I find it incredible, triple the number of human beings in what seems like the blink of an eye and the world transformed utterly. Human population density is a factor in every environmental problem I have ever encountered, from urban sprawl to urban overcrowding; disappearing tropical forests to ugly sinks of plastic waste, and now the relentless increase of atmospheric pollution. I've spent much of the last 50 years seeking wilderness filming animals in their natural habitat and, to some extent, avoiding humans. But, over the years, true wilderness has become harder to find. m1s58-m3s03
