These pollutions might be in the dining hall, kitchen, our rooms etc. Garbage, hair spray, kitchen cleaner, insect killer etc was the main source of indoor pollution. Just as we are now trying to reduce the outdoor pollution, we can also reduce the pollution inside the house. Remember that most of the things start from zero; just like if we want a pollution free world, we must start from our house.
