India is industrializing. This is kind of the natural progression of industrialization. Historically it takes a generation or two of a population living through the shit before they simultaneously realize how bad it is AND have the resources and institutional knowledge to implement and manage higher levels of tech to mitigate It

Look at the US. It took us accidentally lighting the Cuyahoga River on fire before voters all agreed “okay I guess we need some kind of environmental agency” and then it took another twenty years before we started to get sulfur emissions and smog under control

Personally, I expect the wealthy developed world to do a lot more legwork cleaning things up, especially because our wealth largely comes from polluting the hardest the last century(and we are still polluting at higher per capita rates). If that means going into India and building them cleaner factories ourselves, that’s a better investment than just waiting for war to break out as ecosystems collapse. Unfortunately it seems most our species prefer the latter
