Step-by-step solution
Eutrophication is the nutrient enrichment of water bodies containing an excessive population of phytoplankton. This leads to an overgrowth of flora and fauna in the water body until the organic deposition makes it warmer and shallower. Warm-water population increases and the final stage is its conversion into a land. Sanitary Landfill is a method of solid waste disposal in which the waste material is buried in the pits dug on the ground and later they get covered by soil. Snow blindness is caused due to UV-B radiat
