Forest decline of the world: A linkage with air pollution and global warming

Abstract

Various forest declines and forest health conditions have been described for forest ecosystems throughout the world. The connection to global warming and air pollution is clear in some area, but not in others. In this study, some evidences that support or contradict air pollution and global warming
being causal factors in reported cases of decline in Eastern North America, Central Europe and Republic of Korea. Many studies suggested that forest decline phenomenon seems to be strongly associated to air pollution and global warming.
