Some philosophers think that the idea of a consequentialist virtue theory is strange, but the real strength of consequentialism is that it can emulate the requirements of other moral theories when it is the case that acting on those theories would improve the world.

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.

You can't imagine anything like nature as we know it without predators.

The Consequentialist trinity is typically regarded in this way: Bentham is crude, Mill's writings are full of howlers and inconsistencies, and Sidgwick was too smart to fully embrace Consequentialism. All of these great traditions in moral philosophy express strands of our moral consciousness and they should all be treated as research programs rather than as fully determinate views that can be leveled by a counterexample or by a clever argument.

It's possible that we'll screw up the climate so badly that most of us will die and a few breeding pairs will remain somewhere in the arctic. What's more likely is that we'll continue remaking the planet, driving many species to extinction, killing millions of people through the indirect effects of climate change, making life even harder for the poor and powerless than it is now, and making it a little more difficult for the global middle class to live the lives to which they have become accustomed - in other words, business as usual, only worse.

Obama's clean power plan, methane regulations, and increased fuel economy standards are about as good as our political system can do at this point in our history. Let's embrace these things, make them work, and push for more, rather than denouncing them because they're 9th best (which they are).
