Answer

Human activities, for example, grazing and land cover changes, have further altered the biogeochemical cycles and exacerbated such uncertainty on the plateau. The burning of fossil fuels and the deforestation and combustion of biomass, the use of pesticides and fertilizers in agriculture, soil erosion due to agricultural and construction practices, and damming of watercourses are among the human activities that have had the most serious impact on the natural environment. If the predicted warming and wetting persists, future biogeochemical cycles will become more intricate.
