5 things I would like to do for the earth

Alan blogged on this one recently (http://haloscan.com/tb/abear/112256521784486340) and I wanted to see what kind of a list I could come up with. How would I help the earth?
1) Mandate less lawn space for people/business, whatever - more trees and flowers to eat the bad stuff in the air and produce the good stuff, while also reducing the odd need for people to water their fricking lawns! This bothers me so much. It's grass. If it was meant to grow, it will grow. Don't people get it? NO NEW WATER IS EVER CREATED ON EARTH. We reuse what we can and we trash the rest. Well, it's getting to be so that our great great grandkids might have it pretty bad on the water front.
2) Tax breaks for anyone purchasing a smart car/hybrid. If we find ways to reward people for buying or even identifying new sources of fuel/power, more people will climb on the bandwagon.
3) Monorails and other forms of public transportation specifically designed to get people out of their cars and off the roads (I say monorails because we've used up so much of our ground space, that it seems deluded to think a typical transit system will work, although I would settle for increased GO train service to and from places outside the Greater Toronto Area - the province needs to start recognizing that commuters now exist from west of Cambridge to east of Courtice and they need to go to other areas of Toronto than the downtown core). Although having the system would not be enough. I think people should maybe have to pay a specific highway tax to drive the roads, unless they can show an active transit pass.
4) Greater rural opportunities for people. I think there needs to be more pressure and reward for people to move to and settle in rural spaces. Urban congestion is terrible. Industry should be congratulated for branching out. (I'd like to say it would be great if all of our rural spaces could be kept as pure and pristine as they are, but given the continued sprawl of mankind, that doesn't seem likely, so intelligent growth seems the best way to go.)
5) Increased tax benefits for charitable giving and participation (ie Habitat for Humanity)

That's all I can think of without repeating some of Alan's ideas - really liked the trees on buildings and windmills in the NWT.
Take care,
