> the air is toxic. Oxygen is the oxadative species that drives our biochemistry. It's a fuel. Oxygen is highly reactive. It is a fantastic evolutionary gradient as it has tons of free and readily available energy to harness. But of course it's also what also wears us down by putting oxidative stress on our cells, DNA, and molecular biology. It causes all sorts of damage as a byproduct of what it is. Oxygen is life and death. The particulates suspended in the air are yet another problem ...
