Question

pls tell anyone about effects of green Revolution and two positive and negative points

Answer 1

Positive impacts of Green Revolution

It increased significantly the production, to almost 2.5 times in wheat between 1960 and 2010. GR has been able to save the lives of millions of people and exponentially increase the yield of food crops. It improved the economic lot of farmers, and their standard of living greatly improved. It reduced the import of food grains.

Negative impacts of Green Revolution

The revolution increased the use of fertilizers. Generally speaking a fertilizer has the chance to soak into the soil and spread to other areas if it rains. It diminishes soil quality due to increased reliance on synthetic fertilizers rather than natural fertilizer, which allow replenishing of nutrients. The increase in mono cropping has decreased soil quality. Nutrients could not be replaced in the soil due to mono cropping. The use of heavy machine causes soil compaction. The pesticides travel through the food chain and are accumulated in higher organisms.
