explain how human activity can affect the carbon cycle.

Brief Explanations:

Human activities like burning fossil - fuels (coal, oil, gas) release large amounts of carbon dioxide into the atmosphere, increasing its concentration. Deforestation reduces the number of trees that absorb carbon dioxide through photosynthesis, also contributing to higher atmospheric CO₂ levels. Land - use changes such as urbanization and agriculture can alter the amount of carbon stored in soil and vegetation.

Answer:

Human activities such as burning fossil fuels, deforestation, and land - use changes can increase the amount of carbon dioxide in the atmosphere and disrupt the natural carbon cycle.
