RECYCLING
Plastics, like diamonds...
ARE FOREVER!
- Only 3.5% of plastics are recycled in any way
- 63 pounds of plastic packaging goes into landfills in the U.S. per person per year.
- Broken, degraded plastic pieces outweigh surface zooplankton in the Central North Pacific by 6 to 1.
The magnitude of our plastic problem
is enormous.
- The American people weigh approximately 50 billion pounds, but 100 billion pounds of plastic resin pellets (the raw materials for consumer plastics) are produced in the U.S. annually.
- 63 pounds of plastic packaging goes to landfills in the U.S. per person per year.
- Only 3.5 % of plastic is recycled in
any way. Reheating plastic gives it a
"heat history" which reduces its
flexibility. Reheating temperatures
are too low to burn off contaminents; therefore, very few plastics
are recycled into the same type of
container or product that they
were originally. Usually, recycled merely means collected,
not reprocessed into useful products
The majority of the plastic that ends up in the Central Pacific Gyre
(an area the size of Texas) has been shown to circulate there for
at least twelve years. Debris lost in the Bering Sea or the western
portion of the Subarctic Gyre will end up there in 3 to 6 years.
Plastic pollution is bad for the millions
of animals that inhabit our ocean
waters and for the people who fish,
swim and recreate there.
Plastic does not biodegrade. When something biodegrades,
naturally occurring organisms break down natural materials
into their simple chemical components. Paper, when it breaks
down, becomes carbon dioxide and water. But plastic, a synthetic
material, never biodegrades. Instead, plastic goes through a
process called photodegradation, where it is broken down by
sunlight into smaller and smaller pieces, all of which are still
plastic polymers. Even this degradation process can take a very
long time. Estimates of 500 years for a disposable diaper, 400
years for a plastic six-pack ring and 450 years for a plastic bottle
have been made. The more plastic we produce, the more we have
to live with...forever!
Often these animals cannot distinguish plastic from food.
Plastic, because of its high molecular weight and the nature
of its chemical bonds, can never be digested. It provides no
nutrients. Eating plastic can cause animals to feel full and not
hungry even though they are not actually consuming food. In
birds, it has been shown that ingestion of plastics can prevent
migration and reproduction, and can eventually cause starvation
and death. In turtles, plastic has been shown
to block intestines and make the animals
float so that they cannot dive for food.
- Toxic chemicals in plastics can make marine
birds and animals sick. Over 80 species of
seabirds have been found to ingest plastic.
Sea bird chicks are especially vulnerable
as they receive high levels of pollution
from the yolk sac and, after hatching,
from food brought by their parents.
- Ninety percent of Laysan Albatross chick carcasses and
regurgitated food boluses contain plastic.
- Marine birds and animals can become entangled in plastic
nets and fishing line. An estimated 100,000 marine mammal
deaths occur this way each year in the North Pacific.
- Chemicals used to make plastics can escape into the
atmosphere during the manufacturing process. Fourteen
percent of the toxic airborne chemicals nationally are from
"plastics sector" releases. These chemicals can be toxic or
carcinogenic, harming both people and animals.
EPA has mandated that California communities reduce and ultimately eliminate
the flow of trash, particularly
non-degradable plastic trash, into the marine environment. Yet on Coastal
Cleanup Day in 2004, in Marin
County alone a thousand volunteers picked up 10,579 pounds of trash from
bay, creek, and ocean shorelines.
The majority of this trash is plastic: plastic fishing line, plastic bags,
plastic toys, plastic containers, plastic
bottles, plastic bits.
