Global warming is said to be a culprit of many destructive natural damages. Many research shows that glaciers in Antarctica and Greenland are melting quickly, which has a detrimental influence on ocean currents. Cold lands are habitats of various polar mammals; therefore, ice melting means that their homeland is shrinking in size, and they will be on the brink of extinction. Furthermore, scientists point out that the global rising temperature results in the death of many coral reefs in many regions and the disappearance of various kinds of fish. It is not to mention the fact that human life has also been threatened. Most meteorologists and marine experts agree that the change of average heat worldwide links to the extensive storms and hurricanes, and other naturally severe disasters happening around the planet. Recently, a devastating tornado has badly torn a coastal state in the USA, killing at least 70 people and destroying a lot of houses and infrastructure. The town mayor said that he had never seen such a violently tremendous natural phenomenon before. Many European countries have also witnessed the rage of Mother Nature when they have been hit by ferocious storms taking months to recover the local people’s normal life. No one will know exactly the future, but the worst scenario of the earth can be predictable for sure if humans continue treating the environment as they are doing. Global warming is an emergency issue that should be resolved immediately.
