Teachers, save “Why Air Quality Matters?” to assign it to your class.

1. Draw a picture of a particulate matter (from air pollution) traveling from the outside environment into your lungs. 2.

Record your voice explaining your drawing and answers https://www.yammer.com/daischina.net/threads/1193675819 "Air pollution doesn’t just make breathing harder for humans. In the Pacific, fish are choking, too." "Plants produce oxygen as a product of photosynthesis. Oxygen spread around the planet about 2.5 billion years ago and this development was extremely important for other life. Animals need oxygen to breathe. If photosynthesis had not evolved there would be no animals." https://www.ck12.org/c/earth-science/early-atmosphere-and-oceans/lesson/Early-Atmosphere-and-Oceans-MS-ES/?referrer=concept_details
