LocalHarvest is a nationwide directory of small farms, farmers markets, and other local food sources in the US. The site uses Google Maps to help users locate local sources of sustainably grown food, and encourages them to establish direct contact with small farms in their local area.
You can zoom in on the map or use a search form to find the small farms, farmers markets and grocery stores that are near your home. By using the map you can reduce your food miles and support local businesses at the same time.
Beyond the Bottle
Beyond The Bottle is a project to map out public sources of water, such as water fountains and community wells. The idea is that instead of buying ever more bottles of water you can reuse your plastic bottles, refilling them at the mapped public sources.
The site includes a search engine so you can search for a map of your town. It also includes a form for users to add locations of water fountains that they know so the usefulness of the map should grow the more it is used.
