Nowadays, the environmental problem is one of the significant issues in the world. There are debates about whether the main environmental problem of our time is the loss of particular species of plans and animals or others.
On the one hand, the loss of particular species of plants and animals is the problem because, if particular animals is extinct, it leads to break food chains that helps to remain ecosystem. For example, eagle is natural enemy to bullfrog. However, eagles were endangered in Korea. Therefore, the number of bullfrogs increased dramatically so, it ate all of creatures living in river. Consequently, growth of the number of bullfrogs makes confusing in the ecosystem and damages to farmers.
On the other hand, the global warming is the problem because, it leads to increase average temperature and damage to people directly. Many countries weather are changing such as tropical climate due to the global warming and it caused island to sink. For instance, Maldives is endangered to sink in the ocean due to increasing sea level. Because of global warming, glaciers are melting in the North Pole. Therefore, the sea level is rising gradually. It damage to lots of island especially, many researchers predict Maldives will sing a few decades later.
To sum up, extinction of particular species of plants and animals is the environmental problem in the world. However, I firmly believe that the global warming could effect many part of our lives. Therefore, it is the significant environmental problem of our time.
