|Seed saving is an agriculture tradition where seeds from crops are stored for use the next year. Over time, selection of seeds best suited to the area changes the characteristics of the plants and their ability to grow in the given climate. There are machines that can clean the seed for storage purposes and are part of the agriculture infrastructure. Individual plants can also be cloned, by taking a part of the plant and allowing it to grow1. The USDA seeks to preserve genetic diversity of plants through gene repository centers located across the United States; these centers are located in different climate regions, including a center in Corvallis1.
Genetically modified organisms, on the other hand, are created in a lab and specific traits are altered within their genetic material2.
