Narendra sprayed over dose of pesticides on his cotton crop. Ramesh says it is a hazard to bio diversity and crop yield. Can you support Ramesh? How?

Yes as the pesticides are chemical in nature as it makes the soil either more acidic or more alkaline i.e. soil becomes less fertile. They also get washed away into water bodies causing pollution which affect marine life like animals and plants. Some pesticides like DDT cause biomagnification i.e. it enters the food chain and its concentration goes on increasing at every trophic level thus causing toxic to higher trophic level organisms. Sometimes it also kills good microbes. Higher doses may damage our crops. Thus it hazardous for crop yield as well as biodiversity.
