In our 21th century almost noone protects nature, and saves animal world. In our time people cut forests, but forests can grow up again.
Everyone should protect nature for our future. But not everyone does it.
We eat the products those nature produses, we drink water, which is one of the most important kind of the environment. And I think if the governtment saves some money for nature, we'll have future. And there is no any disadvantages of protecting nature, and saving her in peace with herself.
