At school today we watched a documentary; 11th hour. The documentary was mainly about the global changes, and the problems we will face afterwards if we proceed as we do today. Every day we put a huge pressure on the earth, without knowing it. I will mainly talk about the global problems the documentary talked about.
The world is getting warmer and warmer. Many people don't think this is a big problem, but just get one thing clear; It is. Why? First of all the ice on arctic will melt, then the sea level will increase. When the sea level increases many countries will face floods and x-people will die and lose their home. The other Big problem is that the ecosystem may collapse, and then just a human brain can think what will happen next.
We build and destroy our own earth. We are geniuses, no doubt about that, but we are too selfish. Our (or many of us) biggest dream is to get rich and successful. But in this process we may be a part of destroying our own earth. For example oil companies, they often get greedy and provide too much oil... Which effect us, and our be-loving earth. Things like that build our earth economically but also destroy it.
The nature saves us for 36 trillion dollars! This was one fact that really got in to me. Most people doesn't appreciate the nature as we should do (I am one of those..). But after knowing this I will appreciate it much more! And I hope you also do.
