Oh goodie.

TL;DR: excess CO₂ in the atmosphere is altering human blood chemistry. It will exceed healthy limits within 50 years if we continue pumping CO₂ into the atmosphere at current rates.

Not to mention what it will do to people who are already unhealthy, and to animal life in general.

And no, beyond a certain level it’s not good for plants, either. That's another myth.

But yeah, let's keep burning gas and oil, and eating meat.

EDIT: see my addendum downthread.

Locking at the state of the world, my suspicion is, that the higher CO2 levels have already had non-negligible negative effects on human brain capacities.

How can we collectively b so stupid?
