Question

Concentrations of atmospheric of CO_2 remained stable until the industrial revolution in the late 1800s. Industrial activity adds CO_2 to the atmosphere but land use (whether land is used for agriculture,open space,or towns/cities) had also contributed to Earths rising CO_2 concentration. How has the change in land use affected the balance of photosynthesis and respiration? How could we change land use or reverse this trend?

Answer 1

The change in land use has affected the balance of photosynthesis and respiration by reducing the amount of land available for photosynthesis and increasing carbon dioxide release. To reverse this trend, we can promote reforestation, afforestation, and sustainable land use practices.

Step-by-step explanation:

The change in land use has affected the balance of photosynthesis and respiration by reducing the amount of land available for photosynthesis and increasing the release of carbon dioxide through deforestation. Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to produce glucose and oxygen. By reducing the amount of land available for plant growth, deforestation and land use changes decrease the overall rate of photosynthesis. Additionally, when trees are cut down and burned or decomposed, they release carbon dioxide back into the atmosphere through respiration and decomposition.

To reverse this trend, we can change land use practices to promote reforestation and afforestation. Reforestation involves replanting trees in areas where they have been removed, and afforestation involves converting non-forest land into forested areas. Both of these practices increase the amount of land available for photosynthesis and the sequestration of carbon dioxide from the atmosphere. Additionally, we can reduce deforestation and land degradation by implementing sustainable agriculture practices, protecting natural ecosystems, and promoting the use of renewable energy sources to reduce the burning of fossil fuels.
