The world has been ending and getting worse and worse since the dawn of humans and their ability to make such pronouncements. We certainly have our problems, but if there is one thing humanity has going for it is that it is adaptable and especially good at using its oversized brain to adapt to new situations.

And if you need something else, jus think about how wonderful it is to be able to drink water and not have to worry if it has been contaminated by human waste from upstream.
