I we don't pay attention to our only home, the biosphere, it can kill us - in a season.
These horrible images come from the California drought. Is it terminal? Whatever the answer to that question the answer to a second question is much more certain. Who or what caused this terrible drought? We did, both globally and locally. Have people started to die of thirst in LA? Not yet; we will be sure to take whatever water resources we need from these hapless creatures to be sure that not one of us dies of thirst. Not yet. Our technology can give us a few more seasons.
