Go live in the sparsely populated Gobi desert, Tundra or in the rainforests of the Amazon.<quoted text>
Again you are wrong about the earth being "too crowded" , if you feel so then go ahead and kill yourself.
The habitable world is getting overcrowded and resources are becoming scarcer and besides most people are of an inferior/dysfunctional kind who're contributing to the escalation of social problems everywhere.
The growing global population is mostly a Third World problem where rampant poverty, high rates of corruption, soaring crime, routine exploitation of the weaker sections of society, inadequate infrastructure, widespread illiteracy, mind-numbing violence and senseless superstitions have bankrupted and nearly destroyed these countries.
This growing population mess can be arrested by educating the masses on the advantages of sustainable living and by the introduction by governments of mandatory family planning measures (contraception) with the stress being on late marriage and procreation of 1 or 2 kids at the most.
