Communtiy gardens/twelve soil orders

A community garden is a single piece of land gardened collectively by a group of people.  Community gardens provide fresh produce and plants as well as neighborhood improvement, sense of community and connection to the environment.  Community gardens may help alleviate one effect of climate change, which is expected to cause a global decline in agricultural output, making fresh produce increasingly unaffordable.  Advocates say locally grown food decreases a community's reliance on fossil fuels for transport of food from large agricultural areas and reduces a society's overall use of fossil fuels to drive in agricultural machinery.The gardens also combat two forms of alienation that plague modern urban life, by bringing urban gardeners closer in touch with the source of their food, and by breaking down isolation by creating a social community.

Something we also discussed were the twelve soil orders and the items that contribute to soil content.
Soils are named and classified on the basis of physical and chemical properties in their horizons (layers). “Soil Taxonomy” uses color, texture, structure, and other properties of the surface two meters deep to key the soil into a classification system to help people use soil information. This system also provides a common language for scientists.  Soils and their horizons differ from one another, depending on how and when they formed.
