Yeah, nature is great. If all it had to handle were billions of people breathing we’d have no issues.
The problem is that modern machines are extremely efficient at dumping CO2 into the atmosphere, but as great as trees are, they’re not all that efficient at removing it. So, if we want to keep CO2 at survivable levels, we either need fewer CO2-emitting machines (ideal) or a machine that takes CO2 out of the atmosphere (so far, impossible at scale). Simply relying on trees isn’t going to cut it.
