Harmful effects of burning fuel are

  1. Burning of Wood and Coal Releases Unburnt Carbon Particles
    This cause asthma(lung diseases or respiratory disease)


       2.Burning of all Fuels Release Carbon Dioxide 

          This is responsible for global warming

      3. Burning of Petrol, Diesel produces Sulphur dioxide
          Also vehicles produce nitrogen dioxide
         These reach the atmosphere,mix with rain water in clouds and form acids
         This rain is called acid rain
          it is harmful for crops,building and soil

     4.Incomplete combustion of fuel produces carbon monoxide

Why we should never sleep in a room with smouldering(burning) coal fire?

Burning of Wood and Coal release unburnt carbon particles

This cause asthma (lung diseases or respiratory disease)
