This Triodos film on Twitter explains how the soil is important, and how intensive agriculture is destroying it.
Surely this is not agriculture? Agriculture means literally worshipping the soil. The farmer worships the soil by nourishing it, for instance by growing legumes which add nitrogen; by promoting creatures which attack pests; by growing trees which provide shade; by keeping plants which attract bees and other pollinators; and in thousands of other ways. Using artificial fertilizers and pesticides simply destroys the soil.
Triodos’s message is to buy organic food. We can also grow our own food organically, and promote forest gardening, the most efficient method.
