You might be absolutely right about the root cause, but as a solution it's completely infeasible. To limit climate change to 2 degrees C, we need drastic action within the next ten years. The only way to drastically reduce the population in a ten year time span is through the use of bombs and bullets, but that solution would do far more environmental damage and require more industrialization than it would eliminate.

The underlying point is that any fix needs to be (as) insensitive (as possible) to population levels, since they will rise and wipe out any emissions cuts achieved by 'hairshirt' lifestyle changes. (I read somewhere that a westerner becoming vegetarian actually has very little impact on their CO2 emissions anyway).

A bigger deal than population increase is that energy use is going to rise massively with just the population we have, as people move out of energy poverty.

We need to make the energy zero-carbon.
