I say, leave the human race to ruin the planet and destroy itself as a consequence. In the long run, it won’t matter. We’re only specks of dust on a rather larger speck of dust floating about in space, somewhere in this thing we call the Universe. If it doesn’t happen in the next hundred years or so, it will happen some time. I don’t care; I’ll be dead and my own constituent parts will be mingling with other matter to no great effect on anything.
Eat, drink and be merry for tomorrow we won’t be able to.
