Limit the age of the elderly. It really isn't natural that we are living to be 90 years old these days. Plus older people just put a strain on a lot of resources both physically and socially. It's just my opinion. I don't actually play on going around putting down old people.
Life expactancy increase at this stage doesnt have any longer major impact on popultaion increase as it does not increase the fertile period for woman. What does have impact medical wise is the reduction of children mortality rate. The main and primary mechanism of nature to control population is getting rid of as many newborn as posible with diseases, predators, sibblings competition. So nature actually dont aim first the old, but first the young.
In nature no known species as a child mortality lower then 50%, in the human race, no country as it higher then 20%.
But let's not aim child and elder, thats what the nazis also tried to do. The solution is really birth control and its working in most countries, world population growth is slowing down on the poast 15 years. Msain problem now is going to be the aged populations, with many people retired while a smaller slice of population is active to maintain their pensions. That will maker for some rough decades and are one of the major risks to industrialized countries economies (probably the main reason for greek bankrupcy since their retiring age was just 45 years). But we can get over it.
