There are several major environmental issues in India that need urgent attention. Some of the key issues are: 1. Air pollution: India's cities are plagued by high levels of air pollution from vehicles, industry, and open burning of waste. 2. Deforestation: Rapid deforestation is leading to loss of biodiversity, soil erosion, and increased greenhouse gas emissions. 3. Water scarcity: Many parts of India suffer from acute water shortage, exacerbated by industrial and agricultural overuse of water resources. 4. Waste management: The lack of effective waste management systems leads to pollution of land and water resources. 5. Climate change: India is highly vulnerable to the impact of climate change, including increased incidence of extreme weather events. To address these issues, several actions can be taken:

• Strengthening environmental laws and regulations to ensure stricter enforcement and penalties for violating them.
• Encouraging the use of clean energy sources such as solar and wind power.
• Promoting sustainable agriculture practices to reduce water use.
• Investing in waste segregation, recycling and proper disposal techniques.
• Encouraging mass transit systems to reduce vehicular pollution in cities.

Overall, there is an urgent need for the government, the private sector, and citizens to work together to address these environmental issues and ensure a sustainable future for India.
