The ecological impact of deforestation on global warming is substantial, as it increases atmospheric carbon dioxide levels. Trees act as carbon sinks by absorbing CO2 during photosynthesis. When forests are cleared, this stored carbon is released back into the atmosphere, contributing to the greenhouse effect and climate change. Moreover, deforestation disrupts ecosystems, leading to biodiversity loss and altering weather patterns, further exacerbating the impacts of global warming and threatening both human and ecological health.
