Microbeads Petition Box and T-shirt in London

Close up of T-shirt and petition box. A coalition of environmental groups marked World Oceans Day by presenting David Cameron with a petition signed by more than 300,000 people calling for the Prime Minister to ban the toxic microplastic particles known as microbeads. Found in products such as facial scrubs and toothpaste, millions of the tiny plastics are flushed unwittingly into the world’s oceans every year where they ultimately end up in the marine food chain.
