Humans are affecting this cycle with the over use of fertilizers rich in phosphorus that are finding their way into the ocean, where the excess is wreaking havoc on the ecosystems. 7 Why did the oxygen cycle start in the Carboniferous? The carbon cycle involves the movement of carbon between the atmosphere, biosphere, oceans and geosphere. Human activities can contribute excess amounts of nitrogen and phosphorus into water. Humans are one of the largest consumers on Earth and hands down use and impact more of the worlds supply of natural resources than any other species. Human activities have mobilized Earth elements and accelerated their cycles for example, more than doubling the amount of reactive nitrogen that has been added to the biosphere since pre-industrial times. How do human beings affect the carbon cycle and oxygen cycle? The other half is absorbed by oceans, watersheds and plants, as part of what's known as "the carbon sink." document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); 2023 (Science Facts). Carbon can be found in the Worlds atmosphere, as well as emitted from the burning of fossil fuels and even breathed out of many species mouth, including humans. We affect these cycles by burning fossil fuels, clearing plants and trees, mining, and adding chemicals to our waterways. Therefore, human causes of eutrophication include the use of agricultural fertilizers. Phosphorus is an important mineral nutrient needed in all ecosystems, it is used as fertilizer to hasten plant blooming as well as used in plant production, which in turn is a key element needed for animals and humans. The volumes and timing of river flows can be greatly affected by channeling to decrease the impediments to flow, and by changing the character of the watershed by paving, compacting soils, and altering the nature of the vegetation. The carbon cycle is important in ecosystems because it moves carbon, a life-sustaining element, from the atmosphere and oceans into organisms and back again to the atmosphere and oceans.
