Scientists are preparing to launch the world's first machine to clean up the planet's largest mass of ocean plastic.

 

科学家们正准备率先使用机器清理地球上最大海洋塑料垃圾堆。
 

 

The system, originally dreamed up by a teenager, will be shipped out this summer to the Great Pacific Garbage Patch, between Hawaii and California, and which contains an estimated 1.8 trillion pieces of plastic.

 

It will be the first ever attempt to tackle the patch since it was discovered in 1997.

 

The experts believe the machine should be able to collect half of the detritus¹ in the patch - about 40,000 metric tons - within five years.

 

In the past few weeks they have been busy welding together giant tubes that will sit on the surface of the sea and form the skeleton of the machine, creating the largest floating barrier ever made.

 

The Great Pacific Garbage Patch (GPGP) spans 617,763 sq miles - more than twice the size of France, and contains at least 79,000 tons of plastic, research found last month.

 

Most of it is made up of "ghost gear" - parts of abandoned and lost fishing gear, such as nets and ropes - often from illegal fishing vessels².
