Just five companies (Monsanto, Dow, Bayer, DuPont, and Syngenta) own more than 60 % of the global
commercial seed supply, and with many of the modern
seed varieties being
hybrids that won't breed true for home gardeners and small - scale farmers, or that have regulations outlawing the collection and replanting of
seeds, today's growers are being locked into a cycle of reduced genetic diversity, which may lead to a potentially dangerous food security situation in the near future.
