The two great ecological challenges of our times are biodiversity erosion and climate change. And both are interconnected, in their causes and their solutions.
Industrial agiculture is the biggest contributor to biodiversity erosion as well as to climate change.According to the United Nations, 93% of all plant variety has disappeared over the last 80 years.
Monocultures based on chemical inputs do not merely destroy plant biodiversity, they have destroyed soil biodiversity, which leads to the emergence of pathogens, new diseases, and more chemical use.
Our study of soils in the Bt cotton regions of Vidharba showed a dramatic decline in beneficial soil organisms. In many regions with intensive use of pesticides and GMOs, bees and butterflies are disappearing. There are no pollinators on Bt cotton plants, whereas the population of pollinators inNavdanya’s biodiversity conservation farm in Doon Valley is six times more than in the neighbouring forest. The UNEP has calculated the contribution of pollinators to be $200 billion annually. Industrial agriculture also kills aquatic and marine life by creating dead zones due to fertilizer run off. Pesticides are also killing or damaging aquatic life .
“Genetically engineered Golden Rice and GMO Bananas are being proposed by corporations hiding behind the cloak of academia as a solution to hunger and malnutrition in the Global South. But these are false miracles.”
Besides the harm to biodiversity and the climate, industrial agriculture actually undermines food and nutrition security. Firstly, industrial agriculture grows commodities for profits of the agrichemical (now also Biotech) and agribusiness corporations. Only 10 percent of the annual GMO corn and soya crop goes to feed people. The rest goes to animal feed and biofuel. This is clearly not a food system that feeds the world.
Secondly, monocultures undermine nutrition by displacing the biodiversity that provides nourishment and the diversity of nutrients our body needs. Herbicides like Roundup do not just kill the milkweed on which the monarch Butterfly larvae feed, they kill sources of nutrition for humans – the amaranth, the “bathua,” and the mixed cropping that produces more “Nutrition per Acre” than industrial monocultures (seeNavdanya’s report on Health per Acre).
