Does that mean you assume reducing population to be easy&#x2F;easier?<p>Increasing our habitat isn&#x27;t simple. But it at least is likely to get more feasible over time. While reducing population seems to be the opposite of our &#x27;nature&#x27; (not that we aren&#x27;t able to go against that) and it requires the cooperation of basically everyone. Which isn&#x27;t required by the former. Cooperation seems to get [insert mathematical function] harder when more people are involved.<p>Sidenote: expansion would of course not exclude taking care of existing habitats.
