A summary of my speech at the United Nations two nights ago, at least what I could fit into six tweets: Humans are the most dangerous animal on Earth. We represent just 0.01% of all living things and yet in our short time here we have already had a catastrophic effect on the natural world: we have destroyed 83% of all wild mammals and 50% of all plants. Of all mammals on Earth, 60% are now livestock, 36% are humans, and just 4% are wild animals. Farmed poultry makes up 70% of all birds on the planet, with just 30% being wild. How sad is it that most of the birds on Earth are not able to fly. That’s what wings are for. We are adding 1 billion people to our planet every 12 years and for every billion people comes 10 billion farm animals at our current rate of meat consumption. This is not sustainable. Every single environmental crisis we face: climate change, ocean acidification, habitat loss, pollution, species extinction - all of them are accelerated by our rapidly growing population. We cannot address the others without addressing the core issue of the problem. Charles Darwin once said “It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is most adaptable to change.” Humans must show evolutionary adaptation by reducing population growth and meat consumption, as well as replacing the fossil fuel economy with a renewable energy economy. Otherwise we are up shit creek without a paddle.
