Carbon dioxide from coal-fired power plants damages forests.

Carbon dioxide from coal-fired power plants does not directly damage forests in the way toxic pollutants do. Instead, CO2 contributes to climate change, which can indirectly stress forests through changes in temperature, precipitation patterns, and increased pest outbreaks. However, the statement as written is false because CO2 itself is not directly toxic to trees - in fact, plants need CO2 for photosynthesis. Other pollutants like sulfur dioxide and ozone from industrial emissions are what directly damage forests.
