Question

Quizplus · Accepted Answer

Human activities such as the burning of fossil fuels and deforestation can lead to increased levels of carbon and nitrogen in the atmosphere, which in turn alters nutrient cycles on a global scale. Additionally, activities such as agriculture and the use of fertilizer can increase nutrient runoff and cause harmful algal blooms in aquatic systems, further impacting nutrient cycles. Therefore, human activities can have a significant impact on nutrient cycles worldwide.
