What role do trees play in carbon dioxide levels in the atmosphere?

Trees play a crucial role in regulating carbon dioxide levels in the atmosphere by absorbing this greenhouse gas during the process of photosynthesis. During photosynthesis, trees take in carbon dioxide from the air and use it, along with sunlight and water, to produce glucose and oxygen. This process not only helps sustain the tree's growth but also reduces the overall concentration of carbon dioxide in the atmosphere, which is vital for mitigating climate change.

The ability of trees to absorb carbon dioxide makes them essential in efforts to combat global warming, as they act as a natural carbon sink. Healthy forests and tree populations contribute to lower atmospheric carbon dioxide levels, emphasizing the importance of tree conservation and reforestation in climate action strategies.
