the global warming

the global warming has been destroying our planet since 20 or 30 years ago, when the human being started destroying trees and green spaces, the trees are very important for the planet, they give us oxigen, and keep the climate normal in all the regions in the planet.
I think that the principal reason for this problem are the insufficient green areas. obviously, the damage is colateral, I mean, the ice in the poles are melting, and the level of the water is increasing, it causes floods in the seaside, and very poor people from those places, lose their houses and possessions.

But all de things which is destroy our world, give us a job, and better style of life, so the humanity has the choise, continue living with a great life (in the present), using natural resources and avoid our child to have a healthy life, or start taking care our planet, and let all the next generations more years.... I think that these days, we have a selfish idea about this sittuation.
