CO2 IS FINE
It doesn't matter how much CO2 you produce, the only thing that matters is that all the CO2 produced is MANAGED in order to return to the initial state.
That means that we can continue burning fossil fuels as long as we plant X trees and build Y CO2 processing plants.
THERE ARE SOLUTIONS
The world is FULL of solutions to all those problems, from planting trees, to directly piping industry CO2 output to other systems, to recycling nuclear waste, to fusion energy and so much more.
So where's the problem ?
As usual, where the power lies, with the people.
That's where the solution is, too.
