A lot of people assume that Styrofoam must be safe since it's often what our takeaway comes in… wrong! Styrene (a component of polystyrene) is a harmful chemical that can leech into food and drink.
"Styrofoam" is a actually called expanded polystyrene (EPS) which is actually just another type of plastic. Styrofoam is a big part of the plastic problem in our Seas. Being 95% air, its buoyancy allows it to float down waterways, eventually making it to the Sea where it gets broken down into smaller pieces and ingested by marine life, it is also easily carried away by wind and often ends up in places other than the landfilland starts to release methane gases that have over 20 times the ozone destroying potency as CO2.
Unfortunately, rogue Styrofoam ends up littering streets and beaches, harming animals and humans as this single-use Styrofoam cup doesn't just go away after you toss it in the bin because that expanded polystyrene cannot be recycled, despite the fact that many of the containers display the recycling symbol.
