What are the negative results of green revolution in india?
Answers
Although the green revolution has played a leading role in making the country self-sufficient in foodgrains, it has created some adverse effects, which are of serious concern. The negative impact of the Green Revolution includes:
1. Disparity in consumption of fertilizers where the district-wise fertilizer consumption in the country varies from 50-200 kg/ha.
2. Excessive use of chemical fertilizer (150-200 kg/ha) as reported from some states like Punjab and Haryana causing destruction of useful microorganisms, insects and worms in soil.
3. Imbalance in nutrient status causing significant deficiency of N, P, K, Zn, S, Mo and B and disturbance of soil texture and its physicochemical properties.
4. Environmental degradation like depletion of stratospheric ozone, nitrate toxication etc. causing health hazards like cancer, methamoglobinemia respiratory illness, hypertension etc.
5. Pollution with heavy metals and pesticide chemicals causing serious damage to food quality from the safety point of view.
