1) Air pollution means any undesirable change in the quality of fresh air.  

Some of the major causes of air pollution in our major cities are:

a) Vehicular pollution.

b) Suspended particulate matter generation due to dust raised by construction activity. 

c) Smoke emitting industries and power plants in and around cities. 

d) Burning of crop residue, garbage, fallen leaves, etc.

2) Effect of air pollution on:

Plants Animals
Decreased rate of photosynthesis due to the dispersal of sunlight as a result of smoke or smog screen formed by suspended particulate matter Decreased respiratory capacity and increased prevalence of respiratory disorders.
Chlorosis or yellowing of plant leaves due destruction of plant chlorophyll. Lower visibility.

3) The two programs are as follows:

  • Organise a seminar for students, teachers and parents to create awareness regarding the harmful effects of air pollution and how it can cause serious health issues to next generation and deteriorate the environment.
  • Organise a pollution-free week monthly in the school where teachers and students will not use vehicles which run on fossil fuels and encourage them to use bicycles or carpool if possible.
