1.

 Every year, over 7.72 trillion kilograms of plastic is washed into the oceans. There are five huge areas in the world’s oceans that are a “soup” of floating rubbish. One of these areas, the Great Pacific Garbage Patch (GPGP), is three times as large as France.

Over a year ago, a group called Ocean Cleanup began using a huge floating screen to try to clean up plastic pollution in the ocean. After several failures, the group is now collecting plastic in the Great Pacific Garbage Patch. But the plastic is spreading out over a large area, so it's impossible to collect it piece by piece. So, the Ocean Cleanup had a plan. They got a long floating U-shaped tube with a screen hanging below it. As the tube and screen are pushed by the water and the winds, the U is meant to collect plastic rubbish, making it easy for a ship to collect and remove the plastic. The system uses the power of the wind and ocean, so it doesn’t need fuel.

The group began testing the first version, called “System 001”, last September. But it soon became clear that the screen was just moving with the plastic, not collecting it. Sometimes plastic would wash over the top of the tube. Even worse, System 001 got broken by surging seas and had to be towed to Hawaii for repairs.

But Mr. Slat, who got the idea for the Ocean Cleanup system, sees the project as an experiment, which means a failure is a chance to learn. The team collected and studied lots of information about what worked well and what didn’t. Then they changed the design. In June, an improved version, called “System001/B” was towed back to the GPGP.

The new version has a parachute (降落伞) attached to it. This makes the system move slightly slower than the plastic, allowing the plastic to be collected inside, as planned. But this success is still just the beginning of the work of the Ocean Cleanup. They want a better and larger system.
