Trees need Fresh Air / poster

Trees need Fresh Air

“Trees need Fresh Air” is a poster illustrating air not only important to us but also trees. Industrial production creates air pollution that causes harm or discomfort to humans or other living organisms. Such as SO2 causes trees to have yellow spots indicating acid burns then limit growth of trees. Forest produce oxygen for human but we hurt them. The poster tries to tell people to this problem and hope them to stop air pollution now.
