Ethics is prescriptive and can change behavior, but usually only at the margins.

Since for me moral demands necessarily flow from human psychology, I don't think we can be obliged to do something that we are not motivated in any way to do. In other words, I'm an "internalist" about morality.

The Paris climate conference in December, 2015 was a recognition that countries bring their climate policies to international meetings rather than create them during the negotiations (much less do they receive orders from the international community and then go home and implement them).

The bizarre thing about the anthropocene is that never has humanity been more powerful and never have individual humans felt so powerless. This is because so much that drives the circumstances of the anthropocene is the aggregation of apparently negligible acts, often amplified by technology, rather than decisive acts by autonomous decision-makers.

If you look at the works psychologists have done about individual reports of wellbeing, what happens is that if you're poor, you are not happy. But once you achieve a certain level of material satisfaction then income has very little correlation with people's reported states of happiness, things like climate matter more, things like the culture of the country in which you're raised matter more and so the things really, let's face it, like individual temperament matter more than these things.

Critics of Consequentialism have often assumed that hedonism (or preference-satisfaction) must be the theory of the good, that the deontic principle must be maximizing, and that the principle should be applied to individual acts. Indeed, this version is often called "classical utilitarianism" and attributed to Bentham and sometimes even to Mill. Rather than a "classical" view it is a recent construction foisted on to the tradition.

I think, questions about what it means to respect nature become very important because just as in human society, for example, part of what it is for me to live a good life as a human being in a human society is to have respect for others around me. Now, that respect, to some extent, can be thought of as being grounded in the rights and interest of others but it also has to do with the stance that I take in the world and what it is that provides meaning and significance in my own life and I think there are similar ideas of respect for nature that apply as well.
