In some ways I like this idea. Children should know more about the environment.
On the other hand, whose version? What if the teachers prefer the no global warming version of things and teach it that way. The one trouble I can see is that many environmental issues are very much subject to personal interpretation, no matter how much science is behind it.
Some basics are pretty easy to teach. Don’t leave your trash on the ground, pollution is bad and so forth. But I can see a lot of controversy coming around with this topic, just because there are so many opinions on the big environmental topics.
What do you think?
