Millions of people
in Bangladesh (and in West Bengal, India) are affected by
arsenic poisoning, which causes skin lesions, cancer, and
eventually death, because of their dependence on
arsenic-contaminated groundwater for their drinking water
supply. Similar symptoms have also surfaced in Inner
Mongolia, China, which if unchecked could grow into a
disaster of catastrophic proportions there too.
