Styrofoam is made of petroleum based plastic. Styrofoam is made up of a mixture of 5% polystyrene and 95% air. It's used for insulation, food boxes and cups, and packaging peanuts. Styrofoam Is hard to recycled, it takes millions of years to decompose completely. People are trying to switch to products made from plants in order to make styrofoam more environmentally safe. I can improve this problem by choosing products that are plant based and recyclable.
