Carbon dioxide is building up in your atmosphere for two reasons the first is that many of your activities actively produce carbon dioxide The second reason is that some of your activities limit the a?

Carbon dioxide accumulates in the atmosphere primarily due to human activities such as burning fossil fuels for energy, transportation, and industrial processes, which release significant amounts of CO2. Additionally, deforestation and land-use changes reduce the planet's capacity to absorb CO2, as fewer trees and plants are available to perform photosynthesis. This dual impact of increased emissions and decreased absorption exacerbates climate change and its associated effects.
