People will suffer and so will nature, but life is likely to go on with a great deal of loss and mourning. Human adaptability and resilience will still be alive, and so will that great need and resource of ours called love.

The idea that we would raise billions of sentient animals, treat them horribly, pollute our waterways with their waste, compromise the effectiveness of our antibiotics so that they grow faster, and then slaughter them with little regard to their suffering so that we can feed off their corpses, will seem to most people unthinkably cruel and barbarous - sort of in the way that we think of medieval punishments, or Europeans today think of the death penalty.

Climate change involves behaviors that are individually negligible, whose impacts go far beyond the spatial and temporal constraints that define our sense of community.

Attitudes are changing very quickly.

I see a lot of individual action when it comes to environmental questions really as a form of politics as a way of communicating with political leaders, much in the same way that acts of civil disobedience during the civil rights' movement were really acts of political communication, trying to get laws changed rather than based on the thought that the individual action would really change the practices of segregation.

Philosophy isn't reading Emmanuel Kant. Philosophy is about thinking hard about what the right thing to do is in a situation and approaching that kind of question in an open-minded and open-hearted way, receptive to a broad range of considerations and interests of other people and other things.

The only way major change in environmental policy is going to happen, the only way, is if there is a very strong, very active popular movement that demands it and such a movement would be unparalleled because it would be a popular movement that says, "Raise our taxes so that we change our behavior."
