大家都知道，由于人类向自然界过度的索取，已经导致了大自然无情的报复：飓风、暴雨、暴风雪、洪涝、干旱、虫害、酷暑、森林大火、地震等灾情不期而至，全世界因干旱等原因而造成的迁移性难民预计到2025年达到1亿人。 惨痛的生态教训，已经引起世界各国和全人类的重视，国际奥委会评估团视察申奥城市，就把生态环境改善列为其中重要的内容。我国高度重视环保工作台，先后出台了许多保护环境的政策和法规，开展了许多保护环境的工作和活动。 我国同时也非常重视保护环境的教育，“绿色学校创建活动”就是其中重要的内容之一，我校的环境保护和绿化工作已取得丰硕的成果。 我们经常看到许多同学在校园里的各个角落捡拾果皮纸屑；用自己的双手去保护校园环境的优美。但是，我们仍然存在着一些不足：仍然有人乱丢纸屑、食品袋废弃物；仍然有人在草坪上肆意践踏；学校的绿化带中，不时发现有深深的脚印、有的地方甚至走成了小道。 同学们，我们是21世纪的主人，环保意识是现代人的重要标志。我们应当切实地树立起时代责任感。心系全球，着眼身边，立足校园。多弯弯腰捡捡果皮纸屑，首先是不要随地乱扔乱丢；多走几步，不要穿越绿化带，践踏绿地。“勿以善小而不为，勿以恶小而为之”，从我做起，从小做起，从身边做起，从现在做起。保护地球母亲，净化绿色校园。 让我们的校园更加美丽吧！
