  • 2. The Significance of Polyethylene <ul><li>Plastic bags are made from polyethylene, the world’s largest commercial polymer. </li></ul><ul><li>Requires petroleum and toxic materials to manufacture. </li></ul><ul><li>It is a recyclable material, however… </li></ul><ul><li>Most bags and wrappers end up in dumps or the ocean. </li></ul>
  • 3. Uses of Polyethylene <ul><li>Plastic bags </li></ul><ul><li>Any sort of food wrapper </li></ul><ul><li>Bottles </li></ul><ul><li>That plastic that electronics always come in </li></ul><ul><li>Anything that you would describe as “plastic” </li></ul>
  • 4. Environmental Concerns: On Land <ul><li>Not biodegradable (takes 1000 years to degrade.) </li></ul><ul><li>Most plastic bags & many polythelene products are not recycled. </li></ul><ul><li>8 billion pounds of plastic enter land based water sources yearly (a large contributor of which are plastic bags.) </li></ul><ul><li>60 million tons of polythene used yearly. </li></ul><ul><li>1 million plastic bags used worldwide a minute. </li></ul>
  • 5. Environmental Concerns: In the Ocean <ul><li>Plastic bags in the ocean go through the process of plastic photodegradation. </li></ul><ul><li>Contribute to the great pacific garbage patch. </li></ul><ul><li>Enter the food chain (along with PCBs absorbed during photodegradation) when consumed by wildlife. </li></ul><ul><li>Can reach humans through biomagnification. </li></ul><ul><li>Can out mass zooplankton (the dominant life in the area) by up to seven times. </li></ul>
