People lost ability to “feel” the nature since some time, and we simply do not care anymore. I think some processes are out of our understanding because we simply not smart enough (or we are to ignorant) and those are simply irreversible and we can not change them.
Others are irreversible because they are in conflict with are “modern way of life” , in any case it is sure that some things are changing, like weather. But still my main concern are people, always.
