I'm not going to buy bug burgers nor rent my stuff.
What we should do is more population control. As a first step stop incentives for having children (Inn the Netherlands you get more child benefit per child the more you have!). It's tough for the people that want big families but we can't continue growing humanity like this.
So we shouldn't be worrying about "big families", we should be worried about voluntary self-extinction. What do you think the correct population should be for the Netherlands or Europe, and what do you suggest we do when we reach it? Obviously the current level of government benefits per child aren't enough to keep the population level stable.

We have to stop viewing world problems as national issues. Just like the climate problem, we can be 'green' because we externalise a lot of our carbon problems to other countries. That's not helpful at all. It's just smart bookkeeping to keep behaving as we are.
