Seventh Mass Extinction Making Solid Gaines

A lot of species- thousands, are going extinct each year because of environmental changes. Human activity causes those changes. A science paper reported that this is actually the 7^th mass extinction in the Earth’s history, rather than the 6^th, because one at the end of the Ediacaran period occurred that wasn’t previously regarded as such.

One of the basic causes of mass extinctions is atmospheric composition changes, like lower oxygen levels. Destroying habitat can occur from chemical changes as well as bulldozers, auto exhaust etc. Human activities are well on the way to making the world sort of uninhabitable for many species including humans. That isn’t anything to worry about of course, if the rich can just get better tax cuts.
