Sometimes it seems that some think that the world biggest problem is that there are too few people on earth. No, it is not. We are killing our ecosystem already now. These other human problems like child mortality, poverty etc are of course emotionally and personally big ones, but resolving them would make world more crowded and not better place at all. My suggestion: if you put X amount of money to increase human population, then you must put also at least same amount to resolve all the next problems what we people generate: over-harvesting, co2 and other greenhouse gases, pollution etc.
