Transcript of Pollution

Intro
Plastic pollution is non-biodegradable waste that can vary in size from large containers, microscopic plastic pellets and particles.
Effects

It affects marine life because sea creatures and sea birds can get caught or entangled in the trash
Plastics can travel in currents for thousands of miles, endangering marine ecosystems and wildlife along the way
Marine animals ingest the plastics thinking that its food. When ingested it blocks the digestive track, gets lodged in the animal's windpipes cutting airflow and causing suffocation, or fills the stomach.
long term effects...
Pacific Garbage Patch
The Pacific garbage patch is a large collection of marine debris in the North Pacific ocean.
The patch is made up of the western patch in Japan and the eastern patch located between Hawaii and California.
There is currently 3.5 tons of trash in the garbage patch.
Cause

Most of the plastic in the Garbage Patch is from land-based soures.
All current plastics only photo degrade in the marine environment.
When people trhrow trash into the ocean, it will end up getting trapped by the North Pacific gyre. Gyres are whirlpool like and is caused by the coriolis effect.
Causes of plastic pollution
It is caused by people being careless and dumping their plastics into the oceans, rivers, disposing it on land.
Plastics can also travel by wind, for example there could be a plastic bag that gets picked up by the wind and ends up into the ocean.
Plastic Pollution

Effects
Many animals like seals, whales and many more are getting tangled in fish nets and other plastic waste.
The toxic chemicals in the plastic will leak into the water and be absorbed into the tissue of the fish. Then when we consume that fish, the toxins will enter us and we will become sick.
The trash will eventually kill off the marine environment. The plastic fragments will go into the water and harm the environment.
What is being done?

A ninteen year old boy named Boyan Slat has founded the Ocean Clean Up. His concept uses natural ocean currents and winds to transport the garbage towards a collective platform.
He uses a solid floating barrier to collect the trash instead of a net so the sealife wont get entangled.
In maryland there is a water wheel that picks up the floating trash that is in the water.
