Plastics- the beginning
Cheap and durable
Alternative to glass and animal products such as ivory
Could be used to replicate a variety of materialsSlide4
Plastics- the problem
Most types created from the fossil fuel, petroleum, a non-renewable resource
Used in a lot of packaging- a large part of the waste in our landfills
Takes a long time to break down- we don’t know how long!Slide5
Plastics- the problem
A lot of plastic never makes it to a landfill
Ends up in habitats of many animals
Pollutes the oceanSlide6
Trash Patches
Pacific – World’s worst
example of pollution
Twice the size of Texas
Floating soup of plastic bags
and other goods which has
collected over many years
because the clockwise, circular
current and lack of wind drives
floating debris into the center
of the gyre.Slide7

It has is estimated that over a million sea-birds and one hundred thousand marine mammals and sea turtles are killed each year by ingestion of plastics or entanglement.
Animals can become entangled in discarded netting and line. Slide10Slide11

Ways to reduce plastic waste…
Reduce- use less plastic by using reusable bags, containers, bottles.
Reuse- plastic bags from the grocery store can be used multiple times
Recycle- plastic is recyclable! And please don’t litter…
Re-buy- buy goods made from recycled materials whenever possible!Slide19Slide20Slide21
Recyclability of Common Materials…
Aluminum cans
: infinitely, and aluminum is a valuable resource!
Paper
: 5-7 times to make new paper, after that must be mixed with something else or used to create something else.
Cardboard: many times
Glass
: infinitely, doesn’t lose quality, and cheaper to recycle than make new glass
Plastics
: once to make same item, then must be created into something else such as fabrics, furniture, and carpetSlide22
