Feedback about Growth of Population

Growth of population is the most concerned problem in every where. It brings to alot of troubles in many aspects such as pollution, living space, poverty and food. Today, after listening about "Food crisis" - presentation of Mey, i suddently think about between these 2 problems. Do Food crisis and Population Growth have the same source? If compare Population Growth to other concerned problems, i think it's the most important. Some problems we can reduce negative consequences, or change it to positive ways. But, for this problem, how can we solve? Yes, we are We are trying to reduce this problem by making family planning, enlarging space in horizon ... but population is still growing. We can't ask people something like stop giving brith or ask them to die, to have more space and more food. No, we can't. So, if ask me how i feel about it, i just can say "Well, Let It Be!"...
