There are several major challenges that India faces in managing its environment sustainably. Some of these include:

• Population growth and increasing urbanization leading to greater demands on natural resources and increased pollution levels
• Limited access to clean water and sanitation facilities, resulting in waterborne diseases and poor health outcomes
• Pressure on forests and other natural resources due to expanding agriculture and industrial activities, leading to deforestation, habitat destruction, and loss of biodiversity
• High levels of air pollution, primarily due to industrial emissions, vehicular traffic, and burning of crop residues
• Climate change and its associated impacts, such as extreme weather events and sea-level rise

Overall, addressing these challenges will require strong political will and concerted efforts from all sectors of society, including government, industry, civil society, and individuals. This may involve implementing policies and regulations to reduce pollution levels, investing in renewable energy sources, promoting sustainable land-use practices, and improving access to clean water and sanitation facilities.
