很多人都认为是人类活动导致了全球气温上升。他们说全球变暖会对我们的环境造成可怕的后果,如干旱和洪水。
政府该做什么来防止全球变暖呢?给出你提议的原因。
地球的温度正在迅速改变。导致很多气候变迁,如热浪、干旱和洪水。科学家认为这是人类活动污染了地球的大气层的结果。如果政府不采取行动来防止全球变暖的话,这可能会成为灾难。他们能够在三个方面上有所行动;支持研究,制订法律和坚持公众知情。
首先,政府能够支持研究。例如,他们应当鼓励公司致力于汽车研发来减少污染。他们也应当支持来自风和水的电力替代能源,而不是来自石油和煤的电源。同时,他们应当主持会议来讨论温室气体排放的影响和可能解决问题的方案。
其次,他们应当制定法律限制公司发出的温室气体。私人公司应当因为遵循这些法律而得到奖励。他们也应当因为创造出污染而受到惩罚。
最终,每个人都是受到全球变暖的影响。所以,政府和个人在解决问题的过程中是很重要的。例如,他们应当鼓励家庭尽可能多的节省能源,尽可能多的使用更高效的灯泡或少用热水。他们也应当鼓励公众回收,因为这对每个人来说都是必须的。另一种节俭能源的方法是公共交通系统。政府应当把钱花在公共交通使公众尽可能容易的节俭能源。
总之,很明确的,各国政府能够做很多事情来防止全球变暖。他们应包括公司,支持科学家和鼓励个人保护地球。

在这一则报导中,我学到很多事,但我第一个想到的是,造成地球变暖的原因是二氧化碳增加。
Inthispaper,Ihavelearnedalotofthings,butIthinkthefirstoneisthecauseofglobalwarming,theincreaseofcarbondioxide.
为什么二氧化碳会增加呢?我想到的原因是人们常常开车、养食家畜、工厂大量排放黑烟……等。不过这些是大家可以一起解决,说不定可以改善地球继续暖化,例如:目的地很近的话可以骑自行车;目的地很远的话,可以搭乘公共交通运输工具;家畜的排泄物经过处理再排入河内;工厂可以建一座废弃处理厂……等。

请大家不要小看二氧化碳的威力,等到海平面上升、都市浸水和农地淹没,到最后就会面临粮食不足的危机了。请大家跟我一起喊:“停止伤害地球的行为吧!我们居住的地球只有一个。”

当全球气候变暖时,世界发生了巨变。
南极,冰雪融化,人类感觉将要处于冰水之中,这是人类自食其果。北极的霸主北极熊,也因全球变暖而逐渐走向灭绝。一直熊妈妈向小熊递来一把剪刀,熊宝宝好奇地问:“妈妈,用剪刀干什么呀?”妈妈以命令的语气回答:“快剪毛,再长这么厚的毛会被热死的!”小熊天真的望着妈妈:“我们住在冰天雪地里,怎么会热呢?这是我们的外衣,没有它会受冻的,不能剪!”熊妈妈的语气中带点悲伤和叹息:“现在全球变暖,在不适应,恐怕就走向灭亡了!”
全球变暖,北极熊无法找到食物,甚至食用小熊,这是被逼无奈呀!人类应当对自己的行为进行深刻的反省,可是,当全球变暖时,人类还无法意识到自己的错误!只知道冬天不再受寒风的折磨,温度上升了,寒冷已离去,只顾着眼前利益,可不知道以后将远离那洁白的雪,原本应在寒冬中开放的花。
当全球变暖时,希望人类早已意识这以后果。趁早弥补,阻止这一切的发生!

我在电视上、网络上经常看到此刻的地球已经被人类破坏的千疮百孔,如果我们在不一样心协力的保护它,地球将在不久的将来彻底的毁灭。随着人类科技的发展越来越快,科学随之产生的负面影响逐渐体现出来,下头我就给大家举几个例子来说明为什么专家会预言地球将在多年后不复存在。
首先全球变暖就是一个例子,天气炎热在酷暑里泡空调成为一项新的“业余爱好”,但人们可曾想过空调会带来什么负面影响呢?空调排出的气体中包含很多的甲烷,输送到外面甲烷也是导致全球变暖的气体,同时空调还会浪费掉很多的电力资源,所以要尽量避免使用空调或适当使用即可。
另一个原因就是:二氧化碳,汽车尾气与工厂废气中包含很多二氧化碳,而二氧化碳最可能导致全球变暖。此刻汽车逐渐增多,太多的尾气严重影响着我们咳嗽、喉哝发炎……。据有关部门统计中国每年的二氧化碳排放量人均排放量到达2。51吨每年!我们周围的环境在恶劣的变化。
更重要的原因就是:森林减少,农田减少,水资源破坏,水污染严重,新鲜的淡水供应成了问题,许多地方吃水已经成了一大问题。此刻国家也在大规模的搞费力,费神,又费财的“南水北调的工程”。
为了拯救地球,全世界的人们都应当做到:不开空调,使用回收环保纸袋,不用塑料袋,乘坐公交车,废旧电池不要乱扔……等生活中的点点滴滴。其实环保并不难,只要大家支持环保就是你给地球最好的礼物,行动起来吧,这就是一股强大的力量!

这是一幅十分趣味的漫画,其中两只鲨鱼在庆贺一个好消息,因为全球变暖,海水五年后就会淹没附近的一个小岛,岛上有一个人在钓鱼。所以,鲨鱼们迫不及待地想吃一餐美味的人肉大餐。
尽管这幅漫画有一些夸张,可是它却指出了一个严重的`事实,那就是由于全球变暖导致的海平面反常地迅速上升,海水逐渐吞噬人们生存的土地,威胁到我们的生命。在最近的一份报告中,科学家预测如果温室效应继续处于失控状态的话,那么日本、印度尼西亚等岛国和其他一些太平洋上的小岛都将从我们的地图上消失。可是,令我们心寒的是这个威胁还没有引起足够的重视,最好的一个例证就是《东京协定》一向无法顺利实施。
所以,我认为此刻已经到了全世界联合起来共同抗击全球变暖的关键时刻,因为没有任何一个政府和个人能够免受其影响。我们需要尽快采取一些实实在在的措施,以期减少二氧化碳的排放,控制全球变暖的趋势。
