Question

How do human beings contribute to the phosphorus and sulfur cycles?

Answer 1

Answer: the answer is simple its adding chemical fertilizers to the soil

Explanation:

Humans can alter the phosphorus  cycle in many ways, including in the cutting of tropical rain forests and through the use of agricultural fertilizers. Crops often cannot absorb all of the fertilizer in the soils, causing excess fertilizer runoff and increasing phosphate levels in rivers and other bodies of water.
