I think the challenge of climate change in particular is the challenge for us to create and produce new norms for a new kind of world. And that's why I think as important as the issue of climate change is, it's even more important than it seems because if we can't evolve very quickly, new norms to deal with issues like climate change, we're not going to be able to survive in the kind of world we've created. So I think, really, the whole nature of democracy, of governance, of global community and of solving the kinds of problems of the 21st Century are really at stake.

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

We're not good at noticing slow, steady changes in our environments, our senses are not very acute compared to those of many animals, and we're pretty awful at abstract thought, much less acting on it.

Attitudes are changing very quickly.

If you look globally you see a patchwork of jurisdictions (nations, states, provinces, cities) that have taken aggressive action on climate change, and a patchwork of jurisdictions that have not. These various policies reflect the politics of each jurisdiction and the values of its citizens.

The problem is that the Enlightenment dream may make too many demands on poor African apes like us. We may just not be up to it.

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.
