Microplastics
microplastics

Microplastics are small plastic pieces less than five millimeters long which can be harmful to our ocean and aquatic life. [source](https://oceanservice.noaa.gov/facts/microplastics.html) Lead image from @maxliboiron's [work](/questions/maxliboiron/07-19-2018/how-to-analyze-plastics-forensically) The "[BabyLegs](/wiki/babylegs)" trawl designed by @maxliboiron is a scientifically rigorous way to collect samples of microplastics out of water, for inspection with a [microscope](/micro). ###Questions [questions:microplastics] ###Activities [activities:microplastics] ###Research notes [notes:microplastics]...
