How does deforestation affect climate change?

Deforestation significantly impacts climate change by reducing oxygen production and increasing carbon dioxide levels in the atmosphere. Trees play a crucial role in the carbon cycle; they absorb carbon dioxide during photosynthesis and release oxygen. When large areas of forest are removed, the carbon storage capacity of these ecosystems is diminished. Consequently, less carbon dioxide is absorbed from the atmosphere, leading to higher concentrations of this greenhouse gas. Increased carbon dioxide levels contribute to global warming, as this gas traps heat in the atmosphere and leads to climate change effects such as rising temperatures and altered weather patterns.

While deforestation does indeed decrease habitat for wildlife, the direct connection between deforestation and its influence on atmospheric carbon levels positions the second option as the more relevant explanation for climate change impacts. The notion that deforestation has no significant impact is inaccurate, as significant evidence demonstrates its correlation with climate disruption. Similarly, the idea that deforestation increases the amount of rainfall overlooks the complex interactions between forests and atmospheric moisture; reduced tree cover can lead to decreased rainfall in many areas, exacerbating drought conditions.
