I just wanted to add some interesting links to environmental solutions that people have developed.
Vertical Farms - A Big Solution in a Small Space
A company in Singapore has come up with an innovative solution for farming that not only cuts down on the amount of land needed to grow plants and food but also reduces pollution and water usage.

Another interesting concept to watch is the idea of green homes and sometimes small green homes. This is from the discovery channel (of course) and has multiple areas to investigate and learn from. The video I watched was a less than 400 sq ft apartment in Hong Kong that uses moving walls on a high tech rail system to provide multiple spaces within the small apartment. It was designed by an architect and is very modern and homey at the same time. Walls move out to provide a kitchen, closet, bath and guest space. I would love to have this apartment or something like it.
There were a dozen more videos including homes with passive solar, reuse of water around the house, rainwater collection systems, alternate material use and other earth friendly options for building.
