(i) Some of the non-biodegradable wastes ( such as pesticides like DDT and metals like mercury) enter the food chain of humens. These non-biodegradable wastes get concentrated in humen beings and damage their health in the long run
(ii) the excessive use of non-biodegradable fertilisers in agriculture makes the soil either too much acidic or too much alkaline. When the soil becomes too acicic or too alkaline, the crop yield is reduced.
(iii) the dumping of non-biodegradable wastes like plastic, glass and metal obects here and there acts as an eyesore and spoils the environment .
