Solution:
Pollutants from man’s activities like effluents from the industries and homes can radically accelerate the aging process. This phenomenon has been called cultural or accelerated eutrophication. During the past century, lakes in many parts of the earth have been severely eutrophied by sewage and agricultural and industrial wastes. The prime contaminants are nitrates
and phosphates, which act as plant nutrients.
