Here is a six minute PBS clip* highlighting how we are destroying the biosphere on which most current life depends. All this only since about 1850, with most changes within the past thirty years. Time is running out.

Humans are making hurricanes worse, as reported in the New York Times. In fairness to us, just imagine when we figured out how to build furnaces and other machines that could harness all that pent up energy in fossil fuels. Wow! All the stuff we could produce. We built better shelter, increased food production, could move us and freight longer distances in far less time (oh, there are a few labor and social issues, but we don’t need to belabor those here). What’s not to love? Well, there are downsides. Human population rapidly increased requiring more fossil fuel energy. Along with this was an increase in our wants, requiring more, you guess it, fossil fuel energy. The results are warming temperatures, expanding landfills, ocean and (somewhat less) air pollution, sea-level rise, more extreme weather, and the sixth extinction of species.
Today we are faced with a choice. Go to negative carbon emissions (i.e., no fossil fuel use and carbon recapture) by 2050 or so or go on as we are doing and run out of resources within the next hundred years, along with the loss of much humanity. It’s a formidable societal “addiction” requiring policymakers willing to risk their careers. You can read more about this elsewhere on my site.
Either way, the earth will survive just fine (at least for the next 500M years).
