How would a drastic reduction in plant life on earth affect the temperature?

A drastic reduction in plant life on Earth would likely lead to an increase in global temperatures. Plants play a crucial role in absorbing carbon dioxide, a key greenhouse gas, during photosynthesis; fewer plants would result in higher atmospheric CO2 levels, enhancing the greenhouse effect. Additionally, reduced plant cover would diminish transpiration, which cools the atmosphere through water vapor release. Overall, these factors would contribute to a warmer climate and potential disruptions to ecosystems.
