Question

What are some of the positive and negative environmental impacts of the Green Revolution? (Subject: Environmental Biology)

Answer 1

Answer.

Positive impacts of Green Revolution

It increased essentially the generation, to right around 2.5 times in wheat in the vicinity of 1960 and 2010. GR has possessed the capacity to spare the lives of a large number of individuals and exponentially increment the yield of food crops. It enhanced the economic part of farmers, and their way of life enormously moved forward. It decreased the import of food grains.

Negative impacts of Green Revolution

The revolution increased the utilization of fertilizers. As a rule a manure has the opportunity to drench into the soil and spread to different regions on the off chance that it downpours. It lessens soil quality because of increased dependence on synthetic fertilizers as opposed to natural manure, which permit recharging of nutrients. The expansion in mono cropping has decreased soil quality. Nutrients couldn't be supplanted in the soil because of mono cropping. The utilization of substantial machine causes soil compaction. The pesticides go through the food chain and are collected in higher creatures. Some of them hold on in soil, air surface water and ground water and keep on poisoning them for quite a while. The long haul introduction to pesticide causes disease. The environmental degradation makes the GR a general wasteful, here and now answer for the issue of food weakness. It diminishes the "biodiversity" of yields on the planet today. Prior to the revolution, there were 30,000 distinct variations of rice. Today there are utilized just ten adjusted rice variations. Therefore, if environmental change, ailment, or an ascent in plague assaulted the yields, the framework would be debilitated. With bring down food grain costs as a result farmers have turned out to be obligated and are presently being found to confer suicide as a result of it.
