population

Today in class we talked about population. There are over 7.5 billion people on the Earth right now and the population is currently increasing by over 73 million each year. I think this is crazy to think about because soon enough there will be about 10 billion people in the world. I don't know what will happen if the world gets over populated. I wonder if in the future, governments will start to limit the amount of babies being born, like in China. I think this overpopulation will definitely be a problem for the future because 90% of the population growth is taking place in underdeveloped countries where most of the families can't provide for their children. Also, the children in these developing countries will not get the health care and education that they need in order for success.
