The correct option is A Both A and R are true and R explains A

Green Revolution involves increased deployment of technologies including the use of pesticides, herbicides, fertilisers as well as new breeds of high-yielding crops to greatly increase global food production. These fertilisers and pesticides used in large scale, have however, caused certain toxic effects to the environment.

1. Synthetic fertilisers contain toxic impurities like cadmium, lead, arsenic and uranium. These elements, when released into soil, lead to pollution of underwater reservoirs by leaching through the soil.

2. Pesticides like endosulfan pollute the air inhaled by humans and animals.
