Jane was very upset when she discovered that her aunt was suffering from asthma. she now wants to reduce air pollution in her area. which action will best her reach that goal?

People suffering from asthma should avoid go near air pollution. It only worsens the situation. Jane can help her aunt from reducing air pollution by asking first, her family members from smoking. Smoking really kills. Then, try to clean her surroundings that can be the possible reason of having thick dusts. Then, awareness to people.

If Jane really wants to help reduce air pollution in her area, what she can start doing is switching to green electricity and green renewable energy sources, followed by developing a local NGO which would bring awareness to people that they should do the same - this will in time increase the healthiness of the air in their area.
