Evolution is not something to be feared. It's to be celebrated, embraced, and understood.

Meat reared on land matures relatively quickly, and it takes only a few pounds of plants to produce a pound of meat.

When I arrived on the planet, there were only two billion. Wildlife was more abundant, we were less so; now the situation is reversed.

Look at a child and realize that their future is in your hands. It's not just those who will be here fifty years from now. The decisions we make in the next ten years will shape the next 10,000 years.

I'm not against extracting a modest amount of wildlife out of the ocean for human consumption, but I am really concerned about the large-scale industrial fishing that engages in destructive practices like trawling and longlining.
