At the Green Free School in Copenhagen, you're more likely to find pupils repairing a bicycle or doing urban farming than sitting in front of a blackboard

So I definitely think a more direct connection to nature and natural systems is vitally needed for many people today, particularly those living in cities or suburbs (or even rural farmland, which is nearly as transformed as more built up places). Breaking down the mental category of "nature" and "not-nature" is very important in my opinion, and the more people that realize there is nowhere that is not nature, the more people who will be environmentally conscious.

That being said, I'm not sure schools with this type of curriculum are the way to go about things. There is use for some people in knowing how to forage for mushrooms, or make things out of clay or natural fibers. And certainly a better understanding of ecology would be a net benefit for society. But school also must teach how to live in society and the cultural and historical context that society developed in - i.e., those things provided by a standard curriculum. It's possible this school includes those things, but its not clear at all from the articles. I think kids need to learn math, science, history, geography, etc in order to understand the society they live in. And such understanding is surely as important as an understanding of ecology and environmental factors when it comes to changing said society.

I think a lot of what is provided by this schools curriculum might be better provided by something like Scouting, which also promotes concern and care for the environment but without sacrificing a standard curriculum to get there.
