Many believe that it is important to protect all wild animals, while others think that it is importa

Every animal has the role in our environment. They are essential for maintaining our ecosystem. Each ones can be the feed for specific animals but I am not sure that all wild animals are the sources of our environment such as fly, mosquito and so on. Due to worldwide pollution, it leads to changes of our environment, although, most government has tried to implement various ways to solve these problem, it doesn\'t seem like to be solved easily. Global warming is the major problem for polar bear in the Artic. There are few polar bears alive, therefore we need to put effort to prevent them. However, I don\'t think we need to protect bugs like mouses, bats and animals can\'t be the food for humans. I believe that we can live without those animals.
