Cultural eutrophication is the process that speeds up natural
eutrophication because of human activity.Due to clearing of land
and building of towns and cities, land runoff is accelerated and more
distorts such as phosphates and nitrate are supplied to lakes and rivers,
Then to coastal estuaries and bays. Extra of is also supplied by treatment
plants, golf courses, fertilizers, and farms.
These will result in an excessive growth of plant life known as an algal
bloom. This can change a lake's natural food web, and also reduce the
amount of dissolved oxygen in the water for people to breathe. Both these
cause animal and plant death rates to increase as the plants take in
poisonous water while the animals drink the poisoned water. This contaminates
water, making it undrinkable, and sediment quickly fills the lake.
Cultural eutrophication is a form of water pollution.(Egal bloom) and
other aquatic plants.
Following this, overcrowding failures and plants compete for sunlight, space and
oxygen. Overgrowth of water plants also blocks sunlight. And oxygen for aquatic
life in the water, which in turn threatens their survival. Algae also grows easily,
thus threatening other water plants no matter whether they are floating, half-submerged,
or fully submerged. Not only does this cause algal blooming, it can cause an array of
more long-term effects on the water such as damage to coral reefs and deep sea animal
life. It also speeds up the damage of both marine and also affected humans if the effects
of algal blooming is too drastic. Fish will Die and there will be lack of food in the area.
Nutrient pollution is a major cause of algal blooming, and should be minimized.
