it's not an unsolvable problem but more like a political issue. year after year it's the same and yet no one does anything. from what i recall it's the farmers from one state burning crop stubble and the resulting smoke gets carried into the other state (in this case Delhi - which is technically not a state). central government has beef with the Delhi government so they won't intervene.
