Global warming

I never thought that so many dangerous things happen in our world. I seldom watch TV and I only hear the news from the radio during I am driving. So, I didn't know about so dangerous issue which growing every day as a global warming. I know what it is and how dangerous it is, but when I started to read and I started to find out more details about it; I became more upset about it. Every wrongs came from us-human. We are destroying forest making deforestation which became also a big issue or we making pollution because of big factories and industry. I know that without wood we can't heat the house and without electricity we can't have light. But maybe is the way to have these goodness and start to protect the environment? We have to be very careful because one day these goodness will finished.
