Question
Human activities interfere with carbon cycle. List any two such activities.

Answer

Following are the two activities which interfere with carbon cycle:
  1. Clearing of forests: Reduced green cover hampers carbonification and thus interferes with carbon cycle.
  2. Burning of Fossil Fuels: Burning of fossil fuels adds carbon to the atmosphere and increases the percentage of carbon dioxide in the atmosphere. It also interferes with the carbon cycle.
