1. Read the title of the article and look at the picture. How can we clean our oceans? Listen and read to find out.

(Đọc tiêu đề của bài báo và nhìn vào hình ảnh. Làm thế nào chúng ta có thể làm sạch đại dương? Nghe và đọc để tìm ra.)


Plastic pollution in our oceans is a major issue that has serious effects on marine ecosystems and wildlife. These days, more and more people are considering reducing the amount of plastic they use, but what about the rubbish that is already in the oceans? In some parts of the world, it forms floating islands of plastic. The largest of these is the Great Pacific Garbage Patch between North America and Japan. It's three times the size of France!

Now, however, one amazing teenager called Boyan Slat has invented a machine, System 001/B, which catches ocean rubbish. It is a huge 600-metre floating barrier of pipes. A net hangs down from the pipes and reaches three metres below the surface of the water. Boyan avoided using fuel in System 001/B, so it has a very low carbon footprint. It uses the ocean currents and wind to move through the water. Ships take away the waste every six to eight weeks.

But how did Boyan do this? He started telling people about his idea on the Internet and asking for help. Eventually, he raised £1.57 million! He also set up a charity called Ocean Cleanup, which now has over 80 engineers, scientists and environmental experts who are all working to change the planet for good.

Boyan shows us that we can make a difference and help protect the planet, no matter how big the problem is. With hard work, fundraising and a good idea, it's never too late to help Planet Earth!
