On the long run pesticides create more problems than they solve. They destroy the soil and ultimately that leads to lower yields. They are not good for our bodies either. That’s why organic agriculture is best. But technology can help. Scientists are investigating the plant microbiome: the billions of bacteria living in roots, leaves and soil that help plants absorb minerals and nutrients, fight disease, and resist drought and heat. The plant microbiome could hold the key to generating more food without the side-effects associated with high-input farming, including damage to waterways and toxicity in food.
