Bottled water a thousand times worse for species lost and resource use than tap water 2021-07-05

These are not small numbers, in a recent peer-reviewed scientific study:

“The scenario where the entire population consumed tap water yielded the lowest environmental impact on ecosystems and resources, while the scenario where the entire population drank bottled water yielded the highest impacts (1400 and 3500 times higher for species lost and resource use, respectively).”

DALY is disability-adjusted life years.

For resource use, so far as I know Barcelona, Catalonia, Spain, does sit on karst limestone, unlike Florida and south Georgia. So the resource effects of bottled water withdrawals from the Floridan Aquifer on our rivers, springs, and wells are probably worse than this study shows. Those lowered water levels in turn affect ecosystems and human health.

Filtered tap water is just as good for human health as bottled water, with far less external effects. Plus filtered tap water does not expose humans to plastics from bottles. Continue reading
