If you’re seeking some good news during these troubled times, look at the ecologically sound ways of producing food that have percolated up from the grassroots in recent years. Small farmers, environmentalists, academic researchers, and food and farming activists have given us agroecology, holistic resource management, permaculture, regenerative agriculture and other methods that can alleviate or perhaps even eliminate the global food system’s worst impacts: biodiversity loss, energy depletion, toxic pollution, food insecurity and massive carbon emissions.

These inspiring testaments to human ingenuity and goodwill have two things in common: They involve smaller-scale farms adapted to local conditions, and they depend more on human attention and care than on energy and technology. In other words, they are the opposite of industrial monocultures — huge farms that grow just one crop.

But to significantly reduce the many negative impacts of the food system, these small-scale initiatives need to spread all over the world.
