Regarding the assertion and reason, choose the right option.
Assertion [A]: Green Revolution had certain toxic effects on the environment.
Reason [R]: High inputs of fertilizers and pesticides are very harmful for the environment.
Green Revolution involves increased deployment of technologies including the use of pesticides, herbicides, fertilizers as well as new breeds of high-yielding crops to greatly increase global food production. These fertilizers and pesticides used in large scale, have however, caused certain toxic effects to the environment.
1. Synthetic fertilizers especially those containing phosphorus and nitrogen also contain toxic impurities like cadmium, lead, arsenic and even uranium. These elements, when released into soil, lead to pollution of underwater reservoirs by leaching through the soil.
2. Pesticides like endosulfan used for killing the tea mosquito bug affecting the cashew and tea plantation, polluted the air inhaled by humans and animals. As a result of this, people started developing cancers, endocrine or hormonal dysfunctions, infertility etc., and children were born with cerebral palsy, severe deformities, cleft palates, mental retardation and other fatal diseases.
