Destroying Planet Earth

Watching this video makes you realize how much damage we do to our planet. Yes, we all try to recycle more or less, but what I don’t understand is how can we make a difference in global warming, when giant companies are allowed to pollute rivers like The Yellow River (Mongolia), lakes, oceans (Indonesia), cities (just look at that picture of Bangladesh), oil sand pollution in Canada.
In Spain is the largest concentration of greenhouses in the world, covering 26,000 hectares and just imagine what all that plastic waste and pesticide does to the sea.
The mines, the landfills of tires around the world, piles of old computers, oil fields, and so much more…
What can we do about all that?
