There is a lot of science showing how HUGE this problem is, unfortunately this is often hard to access. So here's a few facts for you to learn & share.
Plastic debris outweights plankton 36:1 in the North Pacific gyre.
Over 700 species are being impacted by plastic.
There is a minimum of 5.25 trillion plastic particles (weighing 268, 940 tonnes) in our oceans.
Chemical pollutants move from microplastics into fish tissue (and into our food chain).
25% of fish from fish markets in the USA contained plastic.
Microplastic has been found inside by animals at the bottom of the deep sea.
