Climate Change and Extinction

Climate change isn’t new. The earth’s climate has always been changing. For instance, they think at one point the earth was an icy ball. At one point, Africa was connected to Latin America — those plates keep moving. I do think mankind has contributed to the recent global warming significantly, but there have been such warming trends in the past — when mankind didn’t exist.

Extinction for species on earth is also not new. At some point, mankind will go extinct, just as the dinosaurs eventually met their fate, which was also caused by a radical and sudden change in their climate. For us, it will be a disruption of the amount of oxygen in the atmosphere. Our current atmosphere is 4 parts nitrogen to 1 part oxygen. At what point does a change in that ratio mean extinction for mankind? Let’s say 9 parts everything else to only 1 part oxygen. Bye bye mankind.
