It's disgusting alright, I remember the TV reports of the Bhopal disaster back in 1984, and the numbers of people affected was staggering.
I did also read that the Indian Government was paid compensation, but even an amount of say $10 million won't go far when 500,000 people were maimed as a result.
Dow DOES however have a responsibility to clean up the Bhopal plant. It's been deactivated, but there's been no cleanup operation. It's another environmental disaster in the making, at what cost?
