We see deforestation; we see the desert spreading; we see massive hunger; we see disease and we see population growth in areas where there are more people living on a certain piece of land than the land can possibly support, and they're too poor to buy food from elsewhere.
我们看到森林被砍伐， 沙漠扩大，饥荒肆虐， 我们看到疾病蔓延，人口增长 使得有限土地上所居住的人越来越多 超出了土地所能供养的极限， 而他们又极端贫穷，无力从其他地方购买食物。
