week 4

    I'm going to talk about global food crisis. I think it's part of economy as well. Soaring food price has been a serious problem in some  countries. The statistics has shown that in just one year, the price of corn has gone up 31 percent on global markets: rice, 74 percent; soya, 87 percent; wheat, 130 percent. Countries in Asia and Africa has been suffering from the food crisis. Multiple reasons such as fertilizer costs, bad weather, and increased demand lead to this problem. The rising demand of oil promotes the production of converting food crops into fuel. The relationship between food crops and fuel means we have both energy problem and food problem at the same time. Food is the basic need for living. As a result, this is a serious problem. However, we haven't find a good way of solving this.
