Which of the following practices adversely effect the environment?
Weeding is the process of removing unwanted plants in a crop. Once weedicides are applied, they contain harmful elements like DDT and many more which can leach into the soil and cause soil pollution and cause death of beneficial micro fauna present in the soil. These weedicides can also reach to the aquatic bodies by runoff water, causing algal blooms and thereby leading to the death of aquatic fauna.
