Answers
Answer:
The Green Revolution, or Third Agricultural Revolution, is a set of research technology transfer initiatives occurring between 1950 and the late 1960s, that increased agricultural production worldwide, particularly in the developing world, beginning most markedly in the late 1960s.
Loss of soil fertility, erosion of soil, soil toxicity, diminishing water resources, pollution of underground water, salinity of underground water, increased incidence of human and livestock diseases and global warming are some of the negative impacts of over adoption of agricultural technologies by the farmers to make the Green Revolution successful. Indiscriminate and disproportionate use of chemicals pollutes the soil, air and water and feed and fodders offered to animals. This may be one of the important etiologies of increased productive and reproductive health problems of livestock.
Answer:
Green Revolution was a period of great increase in production of food grains (especially wheat and rice) that resulted in large part from the introduction of new, high-yielding varieties, beginning in the mid-20th century. It has some negative effects as below:
1. The use of chemical fertilizers and pesticides caused erosion and pollution.
2. Loss of genetic diversity.
3. In drier locations, wheat yield gains fell drastically.
4. Excessive irrigation led to problems like leaching, water logging, etc.
