Save the Earth, Do this!

We shouldn't do anything to save the Earth; the Earth isn't worth saving. In the grand meaninglessness of life in this universe, there is no purpose to ensuring the survival of any given planet. To assign any objective value to the one we live on is an attempt to impose meaning on a pointless system. Also, to save the Earth as it is assumes that its current state is preferable to one in which it is not saved. Global warming causing mass extinction isn't a bad thing just because it's inconvenient for our species. There is no saving the Earth, just existing on it.
