First, phytoplankton provide and estimated 50% of the world’s oxygen but it’s much of that goes into water to be used by fish and other sea-based life-forms.Other marine plants provide a fair amount with land-based plants providing the rest – since it mainly all comes from photosynthesis.
Also, we cannot kill the Earth. Outside of blowing it up with a planet buster bomb from sci-fi movies, we’re not capable of that sort of global destruction.
Remember, the Earth has gone through extinction periods in the past where 75-90% of ALL animal died – and yet we’re here to write and complain.
No, we cannot kill the Earth. It will be here long after we are gone. Of course, the decisions we are making, will determine whether our grandchildren will have any air or water left to use. But hey, that’s their problem!

Well, 98% of our oxygen comes from algae (as in seaweed)… so no one’s going to asphyxiate if we burn the Amazon. Well, the environmentalists might.

98%? Try about 50. But thanks for playing…

Sadly, the “good wages” part is already anachronistic these days.
