It's a bit much to blame all the sins of the world on a high birth rate. War, resource depletion, global warming, crime....much of what you list has been pursued by western capitalism. Fossil fuel production, including fracking, dirty coal, and heavy oil benefits the western democracies mostly and fuels a lifestyle that most of the planet have yet to enjoy.
Not saying that population growth isn't a concern; just bloody tired of first world men identifying it as our most serious problem...particularly after the dirty wars of the last couple of decades...........and the absolute indifference I still see to the crimes in Palestine, the bombing of Yeman, and the sytematic interference by neo-liberal western governments in the affairs of other countries.
Why not give population a rest for a while, and work to eliminate war, weapons manufacturing, and the willingness of western governments to condone violence in the Middle East and elsewhere.
That is doing more to deplete the resources of the planet, and make large tracts of the earth unliveable, than live births......and until we change our violent and wasteful lifestyles, its a bit hypocritical to go on about rising birthrates in the poor parts of the world. They are the vicitms of our resource grabs....not the causes of most of it.
