Nutrient pollution, a form of water pollution, refers to contamination by excessive inputs of nutrients.It is a primary cause of eutrophication of surface waters (lakes, rivers and coastal waters), in which excess nutrients, usually nitrogen or phosphorus, stimulate algal growth. [1]
The term nutrient recycling appears in a 1964 paper on the food ecology of the wood stork: "While the periodic drying up and reflooding of the marshes creates special survival problems for organisms in the community, the fluctuating water levels favor rapid nutrient recycling and subsequent high rates of primary and secondary production" [47]: 97
[55] [56] [57] Bacteria that live in detrital sediments create and cycle nutrients and biominerals. [58] Food web models and nutrient cycles have traditionally been treated separately, but there is a strong functional connection between the two in terms of stability, flux, sources, sinks, and recycling of mineral nutrients. [59] [60]
Nutrient depletion can refer to shifts in the relative nutrient composition and overall nutrient quantity (i.e. food abundance). Human activity has changed both in the natural environment extensively, usually with negative effects on wildlife flora and fauna. [4] [5] The opposite effect is known as eutrophication or nutrient pollution. [6]
Sustainable living describes a lifestyle that attempts to reduce the use of Earth's natural resources by an individual or society. Its practitioners often attempt to reduce their ecological footprint (including their carbon footprint) by altering their home designs and methods of transportation, energy consumption and diet.
Green waste is an integral part of many manufactured topsoils, as it provides both nutrients for growing plants and increases the volume of manufactured topsoils. [4] Its woody components do not decompose quickly, so they provide the bulk that is necessary for supplementary topsoils. [ 4 ]
