人类要活下去
人类正面临着越来越多的问题，这些问题威胁着人类的生存。资源将很快被用完，许多疾病还不能治愈，研究表明，污染问题和人口问题正在变得越来越严重。
因此，有些人怀疑将来人们能否活下去。我们正在用尽自然资源，我们正在遭受不可治愈的疾病之苦。由于污染，我们将喝不到生命所需要的净水，也吸不到新鲜空气。人口问题也是一个大问题，地球正在变得拥挤。一些人的悲观预见是：将来人类会灭绝。
当然，他们有点夸大其词厂。但是情况确实严重。我们应当尽最大努力使世界更美好以便我们能够活下去。我们能找到新东西，譬如，能找到太阳能来取代传统的资源。借助科学，我们也能够发现保护人民健康的新方法。通过新的途径防止污染和控制人口。总而言之，我们不要害怕这些问题，不必为此担忧。积极行动起来，使情况变得更好以便人类活下去，这是我们的责任。
