Nowadays, there are lots of organizations whose main purpose is protect endangered animals, in my view this is vital to preserve them for future generations.

First of all, there are almost five thousand animals that are in danger over the world, such as pandas, seals and some types of fish, this is due to their reproductive cycle, most of them have one offspring once a year, as well as the indiscriminate hunting. We must look after this species, if we donít the youngsters will only be able to see them from books. In addition, we cannot do without them, they are part of our environment and its natural balance.

On the other hand, some people disagree, they think that millions are being invested setting up new organizations for animals, instead of using them for protecting human rights.

To summarize, I think that every living being must be protected, and every government should support everyone who comes up with ideas to make this happen.
