Define Cultural eutrophication

Explanation

Cultural Eutrophication. In the older lakes, the fertility gradually increases due to introduction of nutrients such as nitrogen and phosphorus. As the fertility increases, plant and animal life burgeons and organic matter begins to be deposited on the lake bottom. Marsh plants also take root in the shallows and begin to fill in the original lake basin. Eventually, the lakes gives way to large masses of floating plants, finally converting into land. So, the eutrophication is the natural aging of lake by biological enrichment of its water. However, pollutants from man.s activities like effluents from the industries and homes can radically accelerate the aging process. This is called as cultural or accelerated eutrophication.
