Well at one time we relied on coal for 90% of our energy as well..with terrible pollution and environmental destruction...I would think that number today is probably closer to 50%?
??
Never the less...personally, I find it interesting, and refreshing, that China see's the need to protect farm land...after all, no farms, no food. So I do not see this ban, or this discussion to be about "class".....this whole idea of protecting farm land is catching on in many parts of this country as well....know your farmer, support local farms, the local food movement, is growing, as is people's knowledge of how energy intensive, how chemical dependent, some farming has become.
