POLYETHYLENE & ENVIRONMENTAL DEGRADATION By: Dustin Koontz

The Significance of Polyethylene Plastic bags are made from polyethylene, the world’s largest commercial polymer. Requires petroleum and toxic materials to manufacture. It is a recyclable material, however… Most bags and wrappers end up in dumps or the ocean.

Environmental Concerns: On Land Not biodegradable (takes 1000 years to degrade.) Most plastic bags & many polythelene products are not recycled. 8 billion pounds of plastic enter land based water sources yearly (a large contributor of which are plastic bags.) 60 million tons of polythene used yearly. 1 million plastic bags used worldwide a minute.

Environmental Concerns: In the Ocean Plastic bags in the ocean go through the process of plastic photodegradation. Contribute to the great pacific garbage patch. Enter the food chain (along with PCBs absorbed during photodegradation) when consumed by wildlife. Can reach humans through biomagnification. Can out mass zooplankton (the dominant life in the area) by up to seven times.

Movements against plastic bags Some independent stores, diners, cafes, and restaurants are using biodegradable bags. Eco-totes are commonly used, especially in countries like Ireland and other European countries that have banned plastic bags. Seattle bag tax coalition intends to have the tax reduce environmental impact. Many similar things across the US are starting to pop up, even in places like Arizona. National geographic expressed environmental concern as early as 5 years ago for this issue.

Proponents of plastic bags The Washington Food Industry is opposed to the bag tax. Companies like plastic bags as they are incredibly cheap. No extra burden on consumer.
