Endangered Animals

Now, many endangered animals exist all over the world. They are endangered by human's activities, for example, poaching and environmental destruction. Then, how can I protect endangered animals as a common individual citizen? I can protect them by asking the government to make the law which prohibits poaching. I can also protect them by saving energy. I would choose "Iriomote Yamaneko" to protect first because Iriomote Yamaneko is the native animal of Okinawa which is prefecture in Japan, and I like Okinawa. However, we have duty to protect not only one endangered animal but also all endangered animals.
