on the endangered list and the case is the destruction of their habitat. As humans developed the land for the use of their living or constructing factories, the forests and jungles are destroyed. To sum up, it is obvious that humans are causing

problem, by letting them know how it is crucial, they can think about how they can protect the animals and make an action. Volunteering activities are a good example. Since pollution is

may foster an awareness of the issue and

actually leads to an improvement. In conclusion, I believe that the reason for the endangerment of many animal species is a negative impact on the environment because of human activities.
