How Have Humans Changed The Phosphorus Cycle? Humans have greatly influenced the phosphorus cycle by mining phosphorus, converting it to fertilizer, and by shipping fertilizer and products around the globe. Transporting phosphorus in food from farms to cities has made a major change in the global Phosphorus cycle. How are humans changing the phosphorus cycle?
How Do Humans Impact Carbon Phosphorus And Nitrogen Cycles? Human activities are substantially modifying the global carbon and nitrogen cycles. The global carbon cycle is being modified principally by the burning of fossil fuels, and also by deforestation; these activities are increasing the carbon dioxide concentration of the atmosphere and changing global climate. What are
How Long Is The Phosphorus Cycle? The movement of phosphate from the ocean to the land and through the soil is extremely slow, with the average phosphate ion having an oceanic residence time between 20,000 and 100,000 years. Is the phosphorus cycle fast? In the atmosphere phosphorus can mainly be found as very small dust
