This European project is based on a French programme called "Plastique à la loupe". The core of our project is to compare the level of plastic pollution along the river banks (or ocean shores) for each partner school and compare the results in order to edit a visual and a leaflet (European level). The comparisons will be based on visual observations but also on scientific analysis (taking samples and collaborating with engineers and laboratories to edit and understand the results). Lastly, our European collaboration aims at encouraging sustainable solutions to reduce our plastic consumption (at school and at home).
