保护少数（保护稀少物种）
我们如何生活会影响环境。环境就是我们周围所有的事物。在地球上，人类正在以大大小小的方面改变环境。我们砍伐树木建造房屋，耕地种庄稼，把垃圾倾入河流、湖泊和海洋。我们张开大网和较大的渔船去捕捞大量的鱼类。类似这样的行为活动影响植物和动物，也影响像土壤和水等事物。
有的时候我们的行动使得某些植物和动物的数量增加。例如，如果你在你的院子里种植玫瑰花，那么在你的周围就会存在很多玫瑰。
我们的行为也能够导致植物和动物的数量减少。如果一个公园变成一个公寓楼，那么那些植物和动物会怎样呢？它们可能或者死去或者被移动到其他地方，这样就会使植物和动物减少。
污染和其他活动有时候引起某一个物种的数量变得如此之少，以至于该物种不能生存。一个处于消亡危险的物种被称之为濒危物种。
