Replacement products can cause more environmental harm than plastic products there were banned, he says. Plastic was a cheap alternative to a variety of other materials during a time of penny-pinching.
Chokers have been worn for centuries and can be made of a variety of materials, including plastic, leather, latex and metal. In addition, two islands - Maui and Hawaii, the Big Island - have already banned polystyrene foam containers. Why it is important: The islands of Hawaii are known for their beaches, yet many of these beaches are now polluted with plastic waste. Leape: Plastic straws are only a tiny fraction of the problem - less than 1 percent. The world has a plastic pollution problem and it’s snowballing-but so is public awareness and action.
