There is lots of research being done on this topic. One study conducted in Wisconsin showed that trees in local forests grew faster with the presence of elevated carbon dioxide, which is a major greenhouse gas. This seems logical as plants and trees “breathe” in carbon dioxide like we breathe in oxygen. However, an elevated presence of ozone was found to stunt tree growth.
Another study conducted at Colorado State University concluded that pollution causes browning on pine tree needles called chlorosis. It ultimately leads to premature death in many of these pine trees, and makes them more susceptible to disease and attack by bark beetles.
