Once garbage burns, especially plastic and other harmful material, that burning trash or dry leaves produces harmful smoke.
Forest fires are primarily due to actually from heat ot lightening. Smoke from wildfires affects air quality.

Air pollution results in the creation of smog which does not allow us to see clearly. It can influence our emotions and even make outdoor activities risky to be performed.
Carbon dioxide is the main example of the pollutants that contribute to climate change by trapping the heat that lies in Earth's atmosphere. This causes warmer temperatures and weather changes due to which the entire earth is affected.
Travel by buses or bicycles rather than by car; these reduce smoke and gas that causes vehicle emissions.
Trees absorb carbon dioxide and leave in the air the oxygen that in return cleanse it. Other than cleansing the air, they give a shelter to the wild animals, making the environment a greener place.
Recycle paper, plastic, and glass. This gives a way of removing trash which otherwise would land in the landfills. This is an effort to reduce wastes through item reuse. It also minimizes pollution caused by burning rubbish.
Use natural, non-toxic cleaners, paints, and other products. This ensures you're not releasing hazardous chemicals in the air.
