Answer:
Humans negatively impact the Carbon Cycle in several ways:
1. Eating plants: When humans consume plants, the carbon stored in those plants is released back into the atmosphere through the process of cellular respiration. This increases the carbon dioxide (CO2) levels in the atmosphere.
2. Cellular Respiration: Humans, like all living organisms, engage in cellular respiration to generate energy. During this process, carbon-containing molecules are broken down, and CO2 is released as a byproduct. This contributes to the increase in atmospheric CO2 levels.
3. Cutting down trees: Deforestation, primarily driven by human activities such as logging and clearing land for agriculture or urban development, disrupts the natural balance of the Carbon Cycle. Trees act as carbon sinks, absorbing CO2 through photosynthesis and storing it in their biomass. When trees are cut down, the stored carbon is released into the atmosphere as CO2, contributing to greenhouse gas emissions.
4. Combustion: Human activities involving the burning of fossil fuels, such as coal, oil, and natural gas, release large amounts of CO2 into the atmosphere. This includes activities like burning fossil fuels for transportation, electricity generation, and industrial processes. The combustion of these fossil fuels releases the carbon that was stored underground for millions of years, rapidly increasing the concentration of CO2 in the atmosphere.
