Which of the following human activities decreases the removal of carbon dioxide?

Deforestation is a human activity that directly decreases the removal of carbon dioxide from the atmosphere. Trees and forests play a crucial role in sequestering carbon dioxide; they absorb CO2 during the process of photosynthesis and store carbon in their biomass. When deforestation occurs, these trees are cut down and often burned or left to decompose, which releases stored carbon back into the atmosphere, increasing overall carbon dioxide levels. Therefore, by removing these trees, the capacity of the environment to absorb CO2 is significantly diminished, leading to an increase in atmospheric carbon dioxide and contributing to climate change.

In contrast, planting trees boosts carbon dioxide removal, using solar panels generates energy while producing little to no emissions and enhances public transportation reduces reliance on fossil fuels, all of which help in mitigating carbon dioxide levels in the atmosphere.
