India faces various environmental challenges that are impacting the country's ecosystems as well as the health of its people. Here are some of the major environmental challenges India is facing today:

• Air Pollution: The rise in air pollution levels is a significant environmental issue faced by India. The sources of air pollution are vehicular emissions, industrial activities, and construction. To tackle this issue, India needs to promote cleaner energy usage and also implement stricter emission norms.
• Water Pollution: Water pollution is also one of the major environmental challenges faced by India. The sources of water pollution are industrial effluents, urban sewage, and agricultural run-offs. India should focus on implementing proper waste disposal mechanisms and also promoting sustainable agriculture practices to curb water pollution.
• Climate Change: India is also affected by climate change due to rising temperatures, erratic monsoons, and extreme climatic events. The government needs to promote policies and initiatives that promote sustainable energy sources, reduce carbon emissions and increase the use of renewable energy sources.
• Biodiversity Loss: India's biodiversity faces significant challenges from habitat loss, deforestation, and poaching of endangered species. To conserve India's biodiversity, the government needs to implement strict conservation measures and also promote sustainable forest management practices.
• Waste Management: India is facing the issue of improper waste disposal, which leads to a host of environmental problems such as air and water pollution, soil degradation, and climate change. The country needs to implement better waste management practices, including segregation, recycling and reduction in waste generation.

To tackle these environmental challenges, the government of India should focus on implementing sustainable policies that promote the use of eco-friendly practices, energy-efficient technologies, and waste management techniques. It also needs to create awareness among citizens and encourage their active participation in reducing carbon emissions and promoting environmental conservation.
