Global Warming

看過國家地理雜誌後,感受到全球暖化的鉅大影響。希望筆下的文章能喚醒別人的關注。



Global warming is a global warning to all human beings living on the Earth. Global warming has become a hot issue, yet I didn't know much about it before reading the latest National Geographic magazine. Now, I realize that we must pay our attention to this issue since it can greatly affect our future and even our lives.

First of all, I have got a question in my mind: Why are there so many people who don't believe the existence of global warming? Many observation and research have confirmed the phenomenon. Undoubtedly, the climate keeps changing naturally over time. Yet, the latest global warming is so unnatural that it is mainly caused by the enormous amount of carbon dioxide released by the human beings.

Global warming can raise the sea level to a state that many lowland regions maybe flooded by seawater finally. In Hong Kong, it's reported that there won't be any winters within 100 years. Globally, the climate will become much dryer and more changeable in which we many find it hard to adapt. These are all observable and short-run impacts of global warming.

Yet, this is not the end of the "disaster". Actually, global warming can cause the extinctions of animals. For example, as the total size of ice sheets worldwide is reducing, many animals like polar bears, Adelie penguins may lose their habitats. On the other hand, the growth periods of many plants are changing at different rate than those of animals. The result is that many animals consume less food and energy than before. Eventually, the well-balanced ecosystem maybe destructed and even collapsed totally.

After reading the articles, I really concern about the effects brought about by global warming on humans, animals and the climate. I feel really sorry for those unique animals which are threatened by the changing environment. I really hope to arouse others' attention towards this issue. Yet, contradictorily, it's unlikely that I will change my current life style. I am not willing to make a change. And I'm sure I will soon forget the issue and start to worry the AL exam. After all, people nowadays are just too busy to think about the most important thing affecting their lives. I believe many people are just like me that we all have faiths in our minds, yet, we've too passive to act.
