Environmental protection is a joke.

I remember that in the book An Inconvenient Truth I read, Gore had such a bridge in his speech about global warming. He said that we humans only know how to destroy the earth's environment. Facing the rising temperature, we are still indifferent. On the contrary, we have been doing things that will worsen the environment. It's like the famous experiment of boiling frogs in warm water. Put the frog in warm water and gradually boil the water. The frog will not jump out until the end. The result of the experiment was that the frog was boiled to death, but Gore changed his optimistic view because he compared human beings to frogs. With the animation demonstration, it was both humorous and thought-provoking.
