• Positive impacts of Green Revolution
Itincreased 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 revolutionincreased 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. Theincrease in mono cropping hasdecreased soil quality. Nutrients could not be replaced in the soil due to mono cropping. The use of heavy machine causes soil compaction. Thepesticides travel through the food chain and are accumulated in higher organisms. Some of them persist in soil, air surface waterand ground water and continueto poison them for a long time. The long term exposure to pesticide causes cancer. The environmental degradation makes the GR an overall inefficient, short-term solution to the problem of food insecurity. Itdecreases the “biodiversity” of cropsin the world today. Before the revolution, there were 30,000 different variants of rice. Todaythere are used only ten modified rice variants. As a result, if climate change, disease, or a rise in pestilence attacked the crops, the system would be weakened. Withlowerfood grain prices in effect farmershave become indebtedand are now being found tocommit suicide because of it.
