Environmental problems and solutions

I was wondering if anyone could help me with this text:

I think the biggest problem to our environment is the humans, we are selfish and we don’t think so long term. Nowadays money is more important than our resources. Even though a lot of problems here and there.there are no progress, but problem is still resistant., we need to teach a lot of things: Teach especially the children how to protect our resources, recycling, waste management, Pollution reduction, etc. It will secure our future but we can change our present too. Electric cars cans reduce a lot of fumes of CO2 destroying our atmosphere, I think we have modern  technology for it but the oil producing countries and industires moves billions of dollars a year and neither goverment wants encouraging electric cars. The  Brazillian goverment can encourage the solar energy but they don’t because the most part of energy here used is produced by public companies and the energy is very expensive, the problem is we have a lot of hydroeletric plants and this attracted  cutting down a lot of trees to install the power plant, and this is threatening the fauna too. It’s hard to talk abou, and this also gives me short of words, it’s possible talking for hours and write a lot of books talking about this,
