Distinguish between natural and cultural eutrophication
What will be an ideal response?
"In nature, apart from human impacts, eutrophication is part of the process of aquatic succession, discussed in Chapter 4 . Over periods of hundreds of thousands of years, bodies of water are subject to gradual enrichment with nutrients. Thus, natural eutrophication is a normal process. Wherever nutrients come from sewage-treatment plants, poor farming practices, urban runoff, and certain other human activities, humans have inadvertently managed to vastly accelerate the process of nutrient enrichment. The accelerated eutrophication caused by humans is called cultural eutrophication."
