Let's use your reasons, but look at it from the opposite side: 1) The largest contributor to the poor air quality in India is the practice of burning to clear fields, cook stoves that use wood, and the burning of cow dung [https://www.vox.com/2018/5/8/17316978/india-pollution-levels...].

One easy way to bring these people out of poverty is to provide them with good economic opportunities (like factory jobs!). High-tech factories would demand cleaner, more stable power (natural gas, nuclear instead of coal, wood, cow dung).

2) India's totally overpopulated, agreed. One way to decrease the population growth is to bring these people out of poverty. Every developed country has seen their birth rate decline once they move to the middle class. These guys need jobs, college, etc, and people will start having less kids!
