What is Plastic

a synthetic material made from a wide range of organic polymers such as polyethylene, PVC, nylon, etc., that can be moulded into shape while soft, and then set into a rigid or slightly elastic form.

Dangers by Plastic Packaging

The most obvious form of pollution associated with plastic packaging is wasted plastic sent to landfills. Plastics are very stable and therefore stay in the environment a long time after they are discarded, especially if they are shielded from direct sunlight by being buried in landfills. Decomposition rates are further decreased by anti-oxidants that manufacturers commonly add to enhance a container’s resistance to attack by acidic contents.

Plastic Bags▪ Each year, about 500 billion to 1 trillion plastic

bags are used worldwide.▪ Because it costs more to recycle than produce

one bag, only 1% of the bags are recycled.▪ It costs $4000 to process and recycle 1 ton of

plastic bags, which are then sold for $32” ▪ A study in 1975, showed oceangoing vessels

together dumped 8 million pounds of plastic annually. The real reason that the world's landfills weren't overflowing with plastic was because most of it ended up in an ocean

▪ If just 1 out of 5 people in our country use cloth bags we can save 1,330,560,000,000 bags over our life time.

Facts and Figures▪ It takes hundreds of years for plastic bags to decompose

and while they do, they release toxins into our soil, lakes, rivers and oceans.

▪  the production of plastic bags requires millions of gallons of petroleum and banning the production would significantly reduce carbon dioxide emissions. reducing plastic bag production in Britain by a quarter would reduce CO2 emissions by 63 tons a year.

▪  In 2006, the United Nations found that each square mile of the ocean has 46,000 pieces of plastic in it.

▪  Plastic bags which pollute our oceans have a bad habit of killing sea turtles in particular.
