Starting off our new project with some new topics to study on, so our class started with a brief introduction to the project. Our topic for project 2 is air quality. It started with a local survey to the nearby places where we then had to talk to people about the air quality of the locality. We found that people were satisfied with the quality of air in Mumbai. We also found that one of the major reason of air pollution is smoking, according to the areas that we observed. And another cause of pollution was the use of carbon incense sticks by the shopkeepers.
