Which human activity has contributed to an increase in greenhouse gases?

Deforestation, which leads to a decrease in carbon dioxide absorption, plays a crucial role in increasing greenhouse gases in the atmosphere. Trees and forests are vital for absorbing carbon dioxide, one of the main greenhouse gases. When trees are cut down or burned, not only is this carbon absorption capability lost, but the carbon stored in the trees is also released back into the atmosphere as carbon dioxide. This process significantly contributes to the greenhouse effect, which leads to climate change.

While urbanization, increased agricultural activity, and industrial expansion also contribute to greenhouse gas emissions, the direct mechanism by which deforestation impacts atmospheric carbon levels makes it a particularly significant factor. With fewer trees, the natural balance of carbon dioxide levels is disrupted, exacerbating the greenhouse effect. Thus, recognizing the role of deforestation highlights the importance of preserving forests and implementing more sustainable land-use practices to mitigate climate change.
