When we damage our water systems, we're putting our own well-being at risk. This pollution also has huge costs for taxpayers and local governments that must clean this trash off of beaches and streets to protect public health, prevent flooding from trash-blocked storm drains, and avoid lost tourism revenue from filthy beaches. NRDC analyzed a survey of 95 California communities and found their total reported annual costs for preventing litter from becoming pollution is $428 million per year.
