Some of the key environmental problems facing South Asia include air pollution, water pollution, deforestation, land degradation, and climate change. Rapid urbanization and industrialization have led to increased levels of air pollution, with major cities such as Delhi and Karachi recording dangerously high levels of particulate matter. Water pollution is a result of untreated industrial and domestic waste, leading to contaminated water sources and a scarcity of clean drinking water. Deforestation is a significant issue in the region due to urban expansion, logging, and agriculture, resulting in loss of biodiversity and disrupted ecosystems. Land degradation, mainly caused by unsustainable agricultural practices, has led to soil erosion and reduced fertility. Climate change is exacerbating these problems, with rising temperatures, erratic rainfall patterns, and increased frequency of extreme weather events impacting agriculture, water resources, and overall ecosystems. These environmental problems have detrimental effects on public health, livelihoods, and the overall well-being of the people in South Asia.
