My opinion about the whole topic

I think the topic was very interesting, I liked it! In the book were the main things about stuff around the environment and I didn't miss something. I liked the short films and group works in the lessons.
I think everyone can do something against global warming, you can try to produce less trash, order your dumped things and conserve water. You should try to reduce your energy using by switch-off the light and other electronical things when you don't need it. It's the least everyone can do without extra costs!
Of course you can do much more than the things above but that are the main points.
