Some philosophers have begun writing sympathetically about predator elimination as a way of reducing animal suffering. From an environmental perspective this is somewhere between naïve and potentially disastrous.

'The anthropocene' refers to the way we live now, in a highly globalized world, characterized by a large human population and powerful technologies that allow for "action at a distance" that aggregate apparently negligible acts into powerful forces that are transforming fundamental planetary systems. In this sense 'the anthropocene' refers to a period in which nature as an independent autonomous domain comes to an end or is under serious threat.

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.

We live on a restless planet in a violent universe.

In much of the world today there are no more chilling words than "I'm from the United States and I'm here to help you."

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.

The problem is that for almost any feature of humanity that you can name, whether it's the ability to suffer, whether it's the capacity to reason, whether it's having lives that can go better or worse, there are at least some other non-human animals that have all of these features as well. So to exclude non-human animals from the range of moral concern but to include all humans, just seems morally arbitrary.
