Question:List the two practises mentioned in the above conversation,which are not environment friendly and give reasons that why do we consider them as harmful?
Explanation:
Substances which are not friendly:Urea,Weedicides
Urea:As with any source of nitrogen, urea itself can damage plants: nitrogen impairs or completely impedes seed germination, and too much nitrogen can give crops a “burn.”Urea exerts both direct and indirect toxic effects on several organs in the body. ... Urea also directly promotes cell death and calcification in blood vessels. Further, elevated urea levels impair the response of fat cells (adipocytes) to insulin.
Weedicides:Weedicides are toxic in nature. They are made up of various harmful chemicals. ... These toxic substances may cause cancer and various other health problem in humans. Also these substances may reach the ground water due to the rain or any other way and in turn enters the human system because of this water
