Filtering carbon dioxide to have breathing air at home isn't difficult. But housing 8 billion people in sealed environment is.
The trouble with CO2 is that already the amount of it in atmosphere starts making us measurably dumber and it is only going to get worse.
1000ppm is a badly ventilated room that causes headache and poor performance on tasks. Imagine experiencing this for your entire life. Imagine ALL kids having trouble with concentration, entire Earth's population getting dumber. As if we did not have problems already...

- lmilcin 5y agoRemoving CO2 from atmosphere is still much, much more expensive than alternatives. People just don't seem to understand the vastness of our atmosphere and the scale of operations that would be needed for this. Our atmosphere weighs ~5 quadrillion (5x10^15) tonnes. We are talking about an apparatus that can suck that amount of gas and process it to remove CO2 that is already very dilute.
