I am concerned that global civilization is collapsing because humanity has exhausted the planet. Ecologically, this is exceeding carrying capacity, which results in population collapse. Such a collapse usually reduces population numbers back a level the planet can then support. For our civilization, I imagine that number is hardly one percent left. I also imagine that those surviving acted to save themselves and kin. My projects aim to create 'Noah's Arks' for those small groups in my home region. I am a retired biological scientist with wide knowledge of nature's workings.
