• Developing countries are particularly vulnerable to industrial crises.Developing countries are particularly vulnerable to industrial crises.
However, industrial accidents such as Bhopal, India are not just an
Indian or even a Third World problem but are industrial disasters
waiting to happen , whether they are in the form of "mini-Bhopals",
smaller industrial accidents that occur with disturbing frequency in
chemical plants in both developed and developing countries, and
"slow-motion Bhopals", unseen chronic poisoning from industrial
pollution that causes irreversible pain, suffering, and death. These
are the key issues we face in a world where toxins are used and
developed without fully knowing the harm that can come from their
use or abuseuse or abuse.
• As a future engineers, discuss the issue.
