What effect does deforestation have on the levels of carbon dioxide oxygen and water vapor in the atmosphere?

Deforestation significantly increases carbon dioxide levels in the atmosphere, as trees, which absorb CO2 during photosynthesis, are removed. This loss of vegetation also reduces oxygen production, leading to lower oxygen levels. Additionally, deforestation disrupts local water cycles by decreasing transpiration, which can result in reduced humidity and altered precipitation patterns, ultimately affecting water vapor levels in the atmosphere.
