Deforestation is another major problem. The Siberian taiga, which houses the world’s largest forest, acts as a crucial carbon sink, helping to absorb CO2 emissions. However, illegal logging, forest fires, and industrial 3. _____ have led to large-scale deforestation, especially in the remote regions of Siberia and the Russian Far East. In recent years, wildfires have ravaged millions of hectares of Russian forests, exacerbated by higher-than-normal temperatures and dry conditions, which scientists link to climate change. These fires release massive amounts of carbon into the atmosphere, further accelerating global warming.
