Today my topic is man-made disaster.
In the world, there are natural disasters, ecological disaster, man-made disasters.
In the natural disaster such as the tsunami, earthquakes and floods, some of the damages are unavoidable, while the man-made disaster is more horrible. Now let me say some about the man-made disasters.
Man-made disasters, it is our own creation. Perhaps some cause that, but make more to bear. The individual feels now nothing, but the disaster is difficult to predict, such as food safety accidents, terrorist attack and so on.
Global warming is a representative of man-made disaster. Now I come to introduce some of the information about it.
In recent years the population increasing that cause global warming is one of the major factors. At the same time, it also makes a serious threat to the balance with natural ecological environment. So many people, only their emissions of co2 will be a surprising number, with factory and car sending out, and their result will be directly causing system of carbon dioxide in the atmosphere, thus formed constantly increased carbon dioxide "greenhouse effect" on the surface of the earth will directly affect the climate change.
At present, the sea is constantly a rising trend, according to experts predict that the next century, the sea level could rise 50cm. If you don't take measures, and freshwater resources will directly cause the destruction and pollution, etc.
Global warming is now no one doubts that global warming is caused by the people. Even if global warming can control a few, but the impact of the disaster is certainly nothing before. Over the years, the disaster was very slow, so that people have noticed it. But now, everyone can see: global ice is melting, sea-level rise, the southwestern United States, Australia, and sub-saharan African drought. Although these disasters incompletely caused by global warming, still to some degree, and they also will be increasing with global warming, eventually, that is endangering the survival of mankind.
The fundamental method is to reduce carbon emissions, such as reducing
population, reducing fossil fuels( coal, oil and gas, etc.), using more new energy (light and water, wind, etc), more creature planting green plants to absorb carbon and give off oxygen to improve the condition, etc. _ et cetera
Since is a man-made disasters, I think we should solve that from the start. Let us make a little contribution to the society, making our motherland more beautiful.
这个世界上,有自然灾害、生态灾难,天灾人祸。

在自然灾害如洪水、地震和海啸损失的,有些是不可避免的,而在天灾人祸更可怕。

现在让我说些关于天灾人祸。

天灾人祸,它是我们自己创造的。

也许一些原因,但让更多的熊。

个人觉得现在没什么,但这场灾难难以预测,如食品安全事故、恐怖袭击之类的东西。

全球变暖是最具代表性的天灾人祸。

现在我来介绍一些关于它的信息。

近年来的人口增长是造成全球变暖的一个重要因素。

同时,这也使得一个严重的威胁,与自然生态环境的平衡。

如此多的人,只有他们的排放的二氧化碳会被一个惊人的数字,工厂和汽车送出去,其结果将直接导致系统的二氧化碳在大气中,从而形成了不断增加的二氧化碳“温室效应”在地球的表面,将直接影响气候的变化。

目前,海是不断上升趋势,根据专家预言,到下个世纪,海平面上升50厘米。

如果你不采取措施,将直接导致了淡水资源的破坏和污染等。

全球变暖是现在没有人怀疑全球变暖的原因是由于人们。

即使能控制全球变暖的影响,但肯定是什么灾难。

在过去的几年里,这场灾难很缓慢,所以,人们都注意到了这一点。

但是现在,每个人都可以看到:全球冰融化,海平面上升,美国,澳大利亚和撒哈拉以南的非洲的干旱。

虽然这些灾害造成的全球变暖,论者仍然在某种程度上,他们也会增加与全球变暖,最终危及人类的生存。

基本方法是减少碳排放,例如减少人口减少化石燃料(煤、石油和天然气,等等),使用更多的新能源(光和水,风,等等),更多的生物种植绿色植物吸收二氧化碳放出氧气,改善状况,等。

_双键中
既然是天灾人祸,我认为我们应该解决的起点。

让我们做一个小对社会有所贡献,使我们的祖国更美丽。
