Nature don't need us, we need nature. But the way mankind is killing what we need is simply astonishing. The day I was opportuned to see what oil spillage did to a one time great ecosystem with fishes flourishing formerly there. It was just a skeleton of its former self. It'd take years and millions of dollars to clean; of which no one is going to do that. It is sad to see the level of abuse the environment had to take at times. Muchas gracias.
