The world now sees a population increase of nearly 80 million every year, most of which comes from under-developed countries. As a result, issues such as the gap between rich and poor, food safety and resource shortages are becoming more challenging.
现在，世界人口数量每年增长将近8000万，大多数是来自不发达国家。因此，像贫富差距、食品安全和资源短缺等问题变得更具挑战性。
