People talk about the idea of special relationships, that is, the morality only really binds people who stand in some kind of contractual relationship with each other but in fact if you take that seriously as a criteria of when we have a moral relationship then it's hard to see why we would have moral obligations to strangers for example or people who live across the sea from us but yet, every decent person believes that we do.

Even if Bill McKibben were to become dictator, future generations would suffer because of the carbon we had already emitted.

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.

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.

Moral revolutions are typically seen retrospectively. Prospectively, the revolutionaries tend to look like crazy people, and sometimes they are.

Progressive Consequentialsm requires us to make the world better but we are under no obligation to bring about the best possible world.

Many environmental questions are in a deep way philosophical, despite our penchant for treating them as if they were only technological, economic, or whatever.
