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.
