4 scientists said they're cutting back on bottled water after measuring the number of microplastics inside

• In a new study, scientists measured the amount of micro- and nanoplastics inside a bottle of water.
• The numbers were so high that some of the researchers said they're cutting back on bottled water.
• It's unclear if micro- and nanoplastics pose a threat to human health.

The average liter of bottled water has nearly a quarter million invisible pieces of ever so tiny nanoplastics, detected and categorized for the first time by a microscope using dual lasers.
