DDT isn't banned in most countries. It's actually recommended by WHO for INDOOR use in Malria control because it's the only viable option. http://www.who.int/mediacentre/news/releases/2006/pr50/en/

I was hoping to only hear Anti Aadhaar FUD in this thread. Had no idea you had your target set on DDT as well.

As for comparision with USA/EU, India is a different country with different set of problem/challenges. Instead of Aping others we should apply our mind to the problem and come up with solution. Aadhaar is the best example of that.
