1 SOURCE: CSA News, February 2011 https://www.crops.org/publications/csa-news “Of the 12 most important classes of environmental problems that plagued past societies and threaten us now, at least 10 are also central to agronomy, crop science, and soil science.

2 SOURCE: CSA News, February 2011 https://www.crops.org/publications/csa-news “When a group of Polynesians arrived some 1,000 years ago on an isolated South Pacific isle known as Easter Island, they encountered a lush, forested landscape.

Data Tells The Real Story”, Harvard Business Review, June 20, 2011, http://blogs.hbr.org/winston/2011/06/local-food-or-less-meat-data- t.html Weber, C.L. and Matthews, H.S. 2008. Food-miles and the relative climate impacts of food choices in the United States. Environ. Sci. Technol. 42: 3508-3513.
