  • A few causes of climate change :
  1. Illegal cutting of trees
  2. Burning of fossil fuels
  3. Release of harmful gases like nitrous oxide in the atmosphere that is formed due to use of synthetic fertilizers
  4. Accumulation of methane gas (accounts for about 16% of greenhouse gas emissions) in the atmosphere due to waste decompostion in landfills. 
  5. Use of chlorofluorocarbons and hydrofluorocarbons in home appliances like refrigerators. (Deplete the ozone layer and impact the atmosphere)
