Слайд 2The Deepest Ocean
The Mariana Trench is the deepest point

on our planet.
The Mariana Trench is found in a remote

part of the Pacific Ocean.

It stretches down to almost 11,000 metres below sea level.

Слайд 3Plastic in the Ocean
Many millions of tonnes of plastic enter

the oceans every year.
You may have seen videos of plastic

floating on top of the sea and of sea animals trapped in plastic.

Researchers have been studying the deepest part of the ocean to find out if it has been polluted by plastic.

Where all the plastic in our oceans finally ends up is not well known.

Слайд 4The Mariana Trench
They found that the concentration of microplastics got

bigger as they got deeper into the ocean trench.
Researchers

collected bottom water and sediment samples from 2500m down to almost 11,000m below sea level. 

The plastics they found were fibres a few millimetres long, probably from clothing, bottles, packaging and fishing equipment.

They also found a plastic bag, like the kind you get at a supermarket, in the deepest part of the ocean.

Слайд 5Exploring Our Oceans
Lots of rubbish was recorded in the database.
These

photos and videos are stored in a database that is

a collection taken from 5010 dives over the last 30 years.

Scientists send submersible underwater vehicles or submarines down to take photos and videos.

Scientists study the oceans through underwater dives.

Some of the rubbish found included rubber, metal, wood, and cloth but plastic was the most common.

Слайд 6Plastic in the Mariana Trench
Single-use plastic is something that is

used once and then put thrown away.
Most of the plastic

(89%) was single use.

Things like plastic water bottles or plastic cutlery are single use.

Слайд 7The Mariana Trench
The study of the Mariana Trench showed that

17% of the plastic had an impact on the things

living there.

Even though it is very deep, things like coral, jelly fish and octopus live in the Mariana Trench.

This study shows us how serious plastic pollution is to our planet.

Слайд 8How Did the Plastic Get There?
Plastic can get into the

ocean directly if rubbish is blown from the beach or

thrown from ships on the sea.

Some parts of the Mariana Trench have higher levels of pollution than some of the most polluted rivers in China.

A different study found that most plastic in our oceans comes from 10 very polluted rivers.

These rivers run through areas where lots of people live; people who use lots of plastic.
