The Effects of Organic Agriculture on the Environment
Erosion is probably the biggest environmental problem facing agriculture at the moment. Studies have shown that organic agriculture can reduce this by some 30 to 50 percent which is significant. Nitrate pollution, nutrification and other related issues are definitely much lower for our organic agriculture basically because they don't use unofficial fertilizers. Energy usage of organic agriculture is probably lower although the impact of on the CO2 and carbon dioxide emissions sorry CO2 and greenhouse gas emissions is a bit more ambiguous. Biodiversity is definitely raised or maintained better by organic systems. And erosion largely owing to the use of cover crops and manure which also helps to keep the soil down is definitely much lower in organic systems.
