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!

Cleaning the Air...

Air pollution is a major issue that has serious effects on our health. It is much worse in cities. Although some measures have been taken, more need to be done.
One city that is taking big steps to reduce air pollution is Birmingham. It wants to create a Clean Air Zone that will improve the air quality for everyone in the city. It plans to do this by improving the public transport system. There are long-term plans over the next twenty years to build three new metro lines and create fast bus routes across the city as well as open new train stations and improve the railways lines.
Other plans are already in place. The city council is encouraging people to cycle more and only use their cars when there is more than one person in each vehicle. It is also introducing a programme to help people and businesses buy electric vehicles.
The council has also come up with ideas to help manage traffic. Their solutions aim to make traffic flow smoothly, so there are fewer traffic jams causing increased traffic fumes. The city centre will become a Clean Air Zone in June this year and people will have to pay to drive their cars here. This will reduce the amounts of nitrogen dioxide and make the air cleaner for the people who live and work there. The city is already on its way to making the air cleaner for its citizens and improving their health.
