The document discusses deforestation and its impacts on climate change. It notes that approximately 30% of the Earth's land is covered by forests. Deforestation is driven by both anthropogenic factors like increasing wood fuel collection and urbanization as well as natural factors like drought and fires. Deforestation is defined as the removal of forests where the land is converted to non-forest use. The impacts of deforestation include increased carbon emissions, degradation of peatlands, and forest fires, all of which contribute to climate change. Countries like Indonesia, Nigeria, Pakistan, and India are discussed in terms of their high deforestation rates and vulnerability to the effects of climate change.
