Excerpt: Improvement in waste management is key to reducing plastic debris in the aquatic environment: reduce or eliminate the release of plastics; lids for recycling bins; strategic placement of trash and recycling containers in public areas; market-based bans and fees for single- use plastic items (e.g., bags, water bottles); enforcement of litter laws; bottle redemption programs may prove to be useful tools to reduce marine plastic debris.

A 2014 study of the U.S. Great Lakes by the 5 Gyres Institute found an average of 43,000 microplastic particles per square kilometre.
The plastic particles include microbeads, which are found in toothpaste and facial scrubs, but also other sources.
Several US states, including Illinois and California, have already moved forward with a ban. New York State is also considering a ban, upon discovering that microbeads were present in 74 percent of water samples taken from 34 municipal and private treatment plants across New York State. This might not be surprising, given that in that state alone more than 19 tons of microbeads go down the drain every year.
In March 2015 the House of Commons voted unanimously in favour of a motion to list microbeads as a toxic substance under the Environmental Protection Act, but the beads are not yet banned in this country.
There are many other sources of microplastics in our waters, too, which include:
- Fishing nets
- Cigarette filters
- Storm drains and street litter
- Plastic sheeting or tubing
- Plastics production or other industrial sources
