Today most resturants allow leftover food to be taken away by people to be eaten later, most often the containers used for this purpose are made from Styrofoam. Not only is using Styrofoam environmentally unsafe, but using Styrofoam for food storage is actually damaging to human health. Styrene from the Styrofoam containers often leak into the food being eaten or stored, causing styrene to actually be stored INSIDE a person's body tissue. Not good. It has also been proven that too much strene build up can lead to fatigue, difficulty sleeping, and have carcinogenic effects. Also not good. If you would like more info, here is a link:
