Yet again, Nature has demonstrated a way to clean pollution. Researchers in Sweden discovered a moss that manages to remove arsenic from water. Within about an hour, the moss removes about 80% of the arsenic, resulting in drinkable water. The current target is the mining regions in Sweden, though the plant and the technique should work other places, too. Currently, approximately tens of millions of people are drinking arsenic-contaminated water. Rather than technological systems, natural systems may be easier, cheaper, and more effective to deploy against pollution.
