The document discusses the oil and food crisis and the importance of local farming. It shows that between 2007 and 2008, gas prices rose 30% and the average food travels 1,500 miles before being consumed. However, locally grown food in Iowa traveled just 150 miles versus over 13,000 miles if sourced conventionally. There is a growing interest in local and urban agriculture to reduce transportation costs and reliance on distant farmland due to high energy prices. Urban farming can benefit the environment by using natural processes instead of heavy machinery and chemicals which have damaged 38% of global farmland since World War II.
