Plastic materials do not breakdown and decay. They are made of inorganic materials which increases their ecological persistence tremendously. The plague of non-disposed plastic materials is being felt worldwide with wind blown litter from plastic shopping bags being the most widespread - every country in the world is familiar with this problem. And because of their thinness, these bags break down quickly but only to the molecular level and no further. And this is where the real problem starts - when these inorganic molecules build up in the sea, they affect the planetary food chain. In some places, including off the coast of California, the level of inorganic plastic molecular material has been measured at up to 6 times the level of plankton in the same test area. That is incredible, and unacceptable. We need to take immediate action to reduce the use of plastic bags world wide. You can start by reusing your plastic bags more than once and teaching your children to do the same.
