关于资源与环境的论文题目大全高中英语
近，全世界的温度都在变暖，主要是全球二氧化碳、甲烷以及氧化亚氮的含量过多。专家估计今年温度要长1。5——4℃。都是因为人类不断的破坏环境造成的。 汽车在马路上不停的奔跑，不停的排放那废气。一点也没有环保的意识，要多骑点单车，减少废气排放量。如果，在红绿灯处堵车，你放下窗，马上一股股废气味迎面扑来，呛你地你直咳嗽。工厂里的烟囱，也毫不放弃一分一秒的时间向瓦蓝瓦蓝的天空排放浓烟，把天空染得黑黑的。有一天晚上，我去广州，看见马路旁的一个烟囱向天空排放废气，那废气比漆黑的天空还要黑，看了就让人心疼。 全世界的温度变暖，农业受到了巨大的影响。生产1吨小麦要1000吨水，生产1吨玉米要1200吨水，而生产1吨稻米则要2000吨水。我国西北地区人均水的总占有量仅是1781吨。与全国的平均人均占有2200吨还差得很多。水资源的不足影响农业生产是很严重的，再加上自然灾害，那就更了严重了。 全球气温的升高导致大陆冰川、山岳冰川逐渐融化，海水总量增多。同时，海水温度也在升高，海水因膨胀而导致海平面上升。气温上升1摄氏度，海平面要升高10厘米，而全球3/4的大城市和占40%的人口都集中在离海岸不过60公里以内的地区。 让我一起来保护地球，让地球母亲恢复自己原来的容貌。只要我们多骑自行车、多种树、少用化学品……就可为地球母亲做出巨大的贡献。保护地球从我做起，从身边做起。

Global Shortage of Fresh Water
人类自诞生起，一切衣食往行及生产，生活，无不依赖于我们所生存的这个星球，地球上的大气、森林，海洋、河流、土壤、草原、野生动植物等，组成了错综复杂而关系密切的自然生态系统，这就是人类赖以生存的基本环境，长期以来，人类把文明的进程一直滞留在对自然的征服掠夺上，似乎从未想到对哺育人类的地球给予保护和回报，在取得辉煌的文明成果的同时，人类对自然的掠夺却使得我们所生存的这个星球满目疮疤，人口的增长和生产活动的增多，也对环境造成冲击，给环境带来压力。 众所周知，人类是以自然环境为生存，延续的物质基础。但是，随着现代工业的发展，自然环境却遭受到愈来愈严重的破坏。大气污染，水污染，陆地污染……以至世界上再也找不到一块净土。 或许你会想，想在重要的是发展科技，科技发达了之后在去环保也不迟，那你到时候可要后悔了。如果我们现在过分陶醉于对抗大自然的胜利，认为我们取得了什么了不起的成就，那我们离灭亡也就不远了 气候变暖，臭氧层空洞，酸雨，有毒废弃物，野生生物灭绝，以及大气、水污染等，这是我们当前面临的一连串全球环境问题，面对这些问题，我们该做些什么呢？ 保护环境，人人有责，但我们现在还只是学生，不可能为全人类的环境作出特别大的贡献，但我们可以从身边的环境做起，从保护学校的环境做起，例如：遵守有关禁止乱扔各种废弃物的规定，把废弃物扔到指定的地点或容器中，避免使用一次性的饮料杯、饭盒、塑料袋，用纸盒等代替，这样可以大大减少垃圾，减轻垃圾处理工作的压力，爱护花草树木，少赠送贺年卡，保持校园清洁等。 以上这些虽是小事，但是，只要大家动手，一起努力，从节约资源和减少污染着手，调整一下自己的生活方式，我们就能为保护地球做出一份贡献。 节约资源，保护环境，做保护地球的小主人。
