It was a big step in the right direction. But itâs important to remember the equally vital contributions that can be made by private citizensâwhich is to say, by you. âChange only happens when individuals take action,â Aliya Haq, deputy director of NRDCâs Clean Power Plan initiative, says.
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 nutrients such as phosphates and nitrate are supplied to lakes and rivers, and then to coastal estuaries and bays.
Eutrophication is the artificial enrichment of an aquatic system by the addition of nutrients[?]. The effect is often unintentional and harmful, indirectly causing the death of aquatic plants and animals. It is primarily caused by the leaching of phosphate or nitrate containing fertilisers into lakes or rivers. Some algae and blue-green bacteria thrive on the excess ions and a population explosion known as algal bloom occurs. This growth is unsustainable, however.
