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. 2 How does human activity affect carbon dioxide levels? The carbon cycle is impacted by human activities. Global carbon dioxide emissions are the most significant driver of human-caused climate change. The causes of nutrient pollution, specifically of nitrogen and phosphorus nutrients, include agricultural runoff, fossil-fuel burning, and wastewater treatment effluent. Humans have changed the natural carbon cycle by burning fossil fuels, which releases carbon dioxide into the atmosphere. How do human activities affect the hydrological cycle? Farming adding fertilizers to crops, because it helps the plants grow by giving the plants nitrogen, the extra fertilizer can enter the local water supply as runoff. To make matters worse, over consumption of fossil fuels are putting large amounts of carbon into the atmosphere causes a loss of a natural protector from the sun, the ozone layer. How is oxygen released in the respiration cycle? With the presence of more fuel, i.e. Reducing oxygen levels thins the atmosphere, allowing more sunlight to reach Earths surface. This extra sunlight causes more moisture to evaporate from the surface, increasing the amount of water vapour in the atmosphere. human effect the carbon cycle by using consumption of fossil fuels of burning objects and trees; the effect on the oxygen cycle is the trees being cut down and being burned which means less plants .
