The radio show To the Best of Our Knowledge recently spent an hour discussing agriculture and the commodification of seeds. The first act follows the story of wheat and our selection for more wheat of poorer quality. Act two discusses the social importance of corn to indigenous communities across North America. In Act Three, a miracle corn growing in Mexico might allow us to drastically reduce agricultural use of nitrogen fertilizer. Finally they cover the Svalbard Global Seed Vault.
It’s worth a listen.
