Increasingly both environmentalists and animal ethicists recognize the enormous destruction caused by animal agriculture.

If I drive my car to the store, those carbon molecules that are emitted actually get into the atmosphere circulation systems and affect climate in a global basis. This is shocking, this is amazing! No one in the 18th Century would have believed that anything like this were at all possible and I don't think we have, as part of our common sense, morality, norms and values that are really responsive to those kinds of issues, to the kind of power that we now are able to exert over the future and over people who live very far from us.

In the last few centuries we've managed to reduce how much we kill each other, we've learned some basic lessons about public health, and life is relatively good for more people than ever before.

I take seriously the idea that we are African Apes who (at least for the moment) dominate the planet, but our psychology is pretty much what it was when we were living in small groups on the savanna.

If you're interested in doing something about climate change as we all should be, all of us who care about future people and creatures that will inhabit this world. Then buying a Prius is a good thing but an even better thing would be to be on the streets demanding urgent action from the United States' Congress.

Environmental philosophy just is philosophy full stop. It only sprung up as distinct subfield because mainstream philosophy was ignoring some of the most important philosophical challenges of our time.

Philosophy is not a body of knowledge to impart to someone, that's why reading philosophy books isn't always the best way of learning philosophy. Philosophy is really more the process of rational engagement, rational reflection with a diversity of views and ideas and opinions and trying to sort of reason your way through to a more reflective position. I think if you look at it that way, philosophizing is to some extent some small way a part of almost everyone's lives although they don't recognize it as such and a lot of people are embarrassed about it.
