What major environmental problems are in China and India?

China faces significant air pollution, largely due to industrial emissions and coal burning, leading to health issues and environmental degradation. Water scarcity and contamination, particularly in its rivers, are also pressing challenges. In India, air quality is critically poor, exacerbated by vehicle emissions and construction dust, while water pollution from industrial discharge and agricultural runoff poses serious health risks. Both countries struggle with deforestation and biodiversity loss, driven by rapid urbanization and economic development.
