Ben I recommend you try building something physical or painting something, maybe create a child or two. I can only guess you maybe never did anything like this to understand what life is all about - creating, rather than destroying.
Nature, nor the sun is destructive at all, life is a positive, additive force. Just beacause some bad forces have succeeded in bringing us to the brink of extinction doesn't make them right, or even that they will win. All we need to do to turn things round to positive, is to want things to be positive. As the saying goes, "Get busy livin', or get busy dyin'".
