"Intelligence is the ability of a species to live in harmony with its environment."

“Martin Luther King, Jr. once wrote that you cannot commit an act of violence against a non-sentient object. Back in 1986, the Green Party of Canada tried to toss me out of the Party for sinking whaling ships on the ground that it was a violent act. I pointed out that the Green Party of Canada supported violence when it was convenient politically — for example they supported and continue to support abortion which is, like it or not, a violent act, certainly more violent than sinking some metal into the sea. Violence is not violent when we justify it, be it abortion, or war, or eating meat for example. I support abortion but I'm not a hypocrite about it — it's violent, I accept that. Every American taxpayer accepts the violence that their tax-dollars fund.”

“We cannot allow activism to be stifled because of all the paranoia going around.”

“We're now in the midst of a 3rd World War, but this time the enemy is ourselves, and the objective is to save the planet FROM ourselves. There's no hope for masses of humanity to do anything — they never have, they never will. All social change comes from the passion and intervention of individuals or small groups of individuals. Slavery wasn't ended by any government or any institution. Women got the right to vote not because of any government. The civil rights movement, the same thing. India with Mahatma Gandhi, South Africa with Nelson Mandela. Again, it's always individuals. You need those individuals with the passion and the energy to get involved. In fact, I don't know of any government or any institutions that are doing anything to solve any of these problems. All over the world, all I am seeing is individuals and non-government organizations that are passionately involved in protecting ecosystems and species, and that's where I see some optimism. That's where I see results are happening.”

“I don't eat fish because there is no such thing as sustainable fishing in the world right now.”

“In a way, the event could also be called the "Holocenic hominid collective suicide event.”

“A virus kills its host and that is exactly what we are doing with our planet's life support system. We are killing our host the planet Earth.”
