India faces several environmental challenges such as air pollution, water scarcity, deforestation, and climate change. Here are some of the measures being taken to address them:

• The government has launched several initiatives to reduce air pollution such as the National Clean Air Programme aimed at reducing pollution levels by 20-30% by 2024.
• Various measures have been taken to address water scarcity, including the Jal Shakti Abhiyan, which aims to conserve water resources, improve drinking water supply, and ensure the proper management of wastewater.
• The government has launched several afforestation and reforestation initiatives, such as the Green India Mission, to increase forest cover and protect the environment.
• India has set a target of reducing greenhouse gas emissions by 33-35% by 2030 as part of the Paris Agreement on Climate Change, and the government has launched various initiatives to achieve this target, including promoting the use of renewable energy sources such as solar and wind power.

While progress has been made in addressing these challenges, much remains to be done for India to achieve sustainable development and ensure a healthy environment for its citizens.
