A staggering 70% of the food we consume worldwide is produced by smallholders. Peasant and indigenous communities, who produce a great deal of this food, have been developing and saving seed for millennia—from Guatemala through Senegal to Nepal. However, today seeds are under threat everywhere. Laws are increasingly limiting what peasants can do with their seeds and criminalizing them, thereby impeding their role as food producers and threatening our food sovereignty. The destruction of agricultural biodiversity is also rising at an alarming rate: at the end of the 20th century, three quarters of the world’s food was generated from only 12 plants and five animal species.
