Slum is a residential place  poeple who are not economically sound to build a house . Here most of the people are  illiterate . There is no awareness in them about the schemes introduced for them , about the process of recycling or reusing and mainly about sanitation facilities. Due to this people dump the waste in the nearby a river or a lake or in an unconstructed land . This obviously causes pollution. As the most of the people are illitrate they don't have jobs . So they will not have a well developed house . They burn  sticks and papers on which they cook food for them . In those papers there would be plastic papers too which burn and release harmful gases which pollute air. Now-a-days are increasing due to lack of jobs .Therefore pollution is increasing  with the number of people and slum areas.
