Greenhouse Effect /Global Warming

6. Greenhouse Effect /Global Warming

As the UN (United Nations) has declared the green house effect / global warming as a major threat to the world , we cannot but worry about it . It is the gradual warming of the air surrounding the earth . There are many factors behind this global threat . Among these the main reason is environment pollution . It is the human beings who pollute the environment and thus invite the worst catastrophe (সবচেয়ে বড় বিপর্যয়)for human civilization . This is exemplified (উদাহরণ দেয়া) by the destruction of rain forests , by the endless movement of vehicles of city streets , by the rapid growth of industry , by the use of detergents . The oceans are also affected because of industrial waste products , oil seeping from damaged supertankers (বড় তেলবাহী জাহাজ) and other maritime disasters (সামুদ্রিক দুর্যোগ) . However the main culprits (অপরাধী) for the green house effect / global warming are carbon-di-oxide gas , methane and CFCS . If we think about the after- effect of the greenhouse effect , no rational being cannot help worrying . The worried climatologists predict that temperatures may have risen to an alarming level for the next century . This could catastrophically (ধবংসাত্মকভাবে) reduce mankind's ability to grow food , destroy wild life and wilderness , raise sea levels , and flood coastal areas and farmland . We are terrified (আতঙ্কিত) that the lower southern part of Bangladesh may one day go under water . In the face of such an alarming situation , no one should remain idle as our mother earth is only one and so we should share her and care .
