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. It is a collaborative citizen science project being undertaken by UK registered charity, Just One Ocean and the University of Portsmouth. The project began in July 2018 and numerous individuals and organisations from around the world have joined the programme. This is not a project that it is time dependent. It is ongoing, with data gathered next year, or even in ten years contributing to our scientific knowledge. so it doesn’t matter if you can’t do a survey because of the snow; it can wait until the snow clears. This project is all about collecting data that we can use. The more we get the better so please feel free to do as many surveys when you want, whenever you want.
