大家都知道什么保护环境的方法？
公共交通 绿色出行
上下学时优先选择公共交通工具或骑车、步行等方式。
积极践行“135”出行方案，即坚持1公里内步行，3公里以内骑自行车，5公里乘坐公共交通工具的低碳出行方式。这样在锻炼身体的同时减少了城市汽车尾气的排放，同时也很好地避免了交通拥堵。
节水惜水 一水多用
无论是在学校还是家中，自觉做到爱水、惜水、节水。用完水后关紧水龙头，养成节约用水，不浪费的好习惯，提高日常生活用水的循环利用率，一水多用、循环利用。比如，洗菜的水可以用来浇花，洗衣服的水可以用来拖地，淘米的水可以用来洗碗等。
垃圾分类 引领风尚
许多同学购买了新文具，替换下来的旧文具在投放时一定要做好垃圾分类的功课。
铅笔、自动铅笔、自动铅芯圆珠笔、水性笔、水性笔芯、橡皮、透明胶带都属于其他垃圾；试卷、课本、习题册、笔记本、剪刀、美工刀、文件夹、笔袋、订书机、书包都属于可回收物。
大家一定要看清楚再投放哦！
珍惜能源 节约用电
生活照明尽量利用自然光，使用节能灯具、节能电器，做到随手关灯。尽量减少空调使用时间，无论在冬天还是夏天都要合理设置空调温度。尽量使用高效率、低能耗电器，出门离家时要及时关闭电源，减少待机耗电。用电脑学习时可以将屏幕调暗一点，既能省电又能保护视力。
节约粮食 践行“光盘”
要珍惜粮食，在学校、在家中用餐时吃多少盛多少。不随便丢弃剩菜剩饭，在外用餐不攀比，倡导“光盘”行动，做到“舌尖上的文明”；同时，减少使用餐巾纸、纸杯、一次性筷子、不可降解塑料袋等，真正做到绿色环保，勤俭节约。
珍惜纸张 守护一片绿
如今，每年全球纸张产、用量已达3.2亿吨，如果以每吨纸需砍伐4棵平均20年树龄的树木作原料的话，那么1年就有近13亿棵这样的大树从地球上消失。
纸与同学们的生活密切相关，更与环保紧密相连。我们要从自己做起、从身边做起，节约每一张纸，在打印学习资料时，将纸张进行双面打印，物尽其用。学习使用后的纸张、报纸、书刊，可以进行分类，用过一面的纸可以翻过来做草稿纸、便条纸，或自制成笔记本使用。

湿地是全球价值最高的生态系统,被人们比喻为“地球之肾”。据联合国环境署2002年的研究数据表明，一公顷湿地生态系统每年创造的价值高达1.4万美元，是热带雨林的7倍，是农田生态系统的160倍。
