Plastic pollution and microplastics in particular are a significant threat to marine ecosystems and human health.

The Big Microplastic Survey is a global project that will use citizen science to gather essential data about microplastics and mesoplastic in rivers, lakes and coastal regions

Get involved!  The project is open to anyone, whether you are an organisation, academic institution, or a concerned individual.  If you have access to a beach, riverbank, lakeside, or coastline you can get involved.
