The Federal Seed Act, Plant Variety Protection, and the Politics of Seed Exchange in the United States, by Julie Julie WassermanFrom the introduction: "The diversity of edible plants that we know and enjoy today is a direct result of our ancestors saving, replanting, and sharing seeds within their communities over millennia. However, over the last century, food crop diversity has been declining at an alarming rate. The United Nations Food and Agriculture Organization estimates that at least 75 percent of food crop diversity has already been lost. This has been attributed to a variety of interrelated trends, such as industrialized agricultural practices and the food system at large, urbanization, government policies, privatization of seed, and the breakdown of community seed exchange networks."
