To make the Indian economy sustainable in the long run, several steps can be taken, including:

• Encouraging the use of renewable energy sources, such as solar and wind power, to reduce reliance on fossil fuels and decrease greenhouse gas emissions.
• Promoting sustainable agriculture practices, including the use of organic farming methods and reducing the use of chemical fertilizers and pesticides, to ensure the long-term viability of India's agricultural sector.
• Investing in public transportation infrastructure and promoting the use of public transportation to reduce reliance on private vehicles and decrease air pollution.
• Encouraging conservation and protection of India's natural resources, including forests, rivers, and wildlife, to maintain ecological balance and reduce the ecological footprint of economic activities.
• Promoting sustainable consumption and production practices, including waste reduction, recycling, and responsible sourcing of materials, to reduce the environmental impact of economic activities.

These steps, if taken in a coordinated manner, can help make the Indian economy more sustainable and ensure a long-term future for the country's economy and its citizens.
