The deaths of 300,000 people by starvation does not even cause a squiggle in world population charts. Even Somalia itself, it is barely a squiggle. The United Nations forcasts that the Somali population will grow from 7.6 million to 18.9 million in the next 30 years. Even if we got the whole world to pay attention to birth rates, it is not clear it would make any difference. People don't have birth rates.
People have babies.
Many of us have now learned that high birth rates are bad, but virtually everyone thinks more babies are good. Quickly, around the whole world, we have to close the loop. UN Population Summit in Cairo will provide some moratorium. This consciously excludes much energy that is vital to life and civilization, but that never enters anyone's ledger books. If you dry your laundry on a clothes line you use no accountable fuel.
