Population

Today in Human Geo we learned things about life expectancy. There are over 7.5 billion people on this planet. The population keeps rising and it worries me. What would humans do if we kept increasing at the rate we are going? I honestly do not know, but maybe some disease will wipe out half of the population. Maybe the United States would instate the law of only having one child like China did. Also with the advancing medical technology, people are living longer and babies are being born faster than people are dying. Life expectancy rates are going up. In Monaco the average life expectancy for women is 93!! I don't quite understand how that could be an average age. I think of 85 to be an average age for the women in my family.
