0:00:12 > 0:00:13Hi, I'm Whitney.
0:00:13 > 0:00:15This is Newsround.
0:00:15 > 0:00:17First to Asia, where there are growing fears
0:00:17 > 0:00:21of an environmental disaster in the East China Sea as a huge
0:00:21 > 0:00:22tanker is leaking oil.
0:00:22 > 0:00:24Here's Ayshah.
0:00:24 > 0:00:31Toxic, black smoke fills the skies as an oil tanker continues to burn
0:00:31 > 0:00:39many hours after it hit a cargo ship via China.
0:00:39 > 0:00:42The Sanchi vessel caught light after the collision two days ago off
0:00:42 > 0:00:43the coast of the city of Shanghai.
0:00:43 > 0:00:46The huge tanker is more than 270 metres long and was carrying
0:00:46 > 0:00:50about a million barrels of oil to South Korea.
0:00:50 > 0:00:52Chinese authorities are now warning that the tanker is in danger
0:00:52 > 0:00:56of exploding or sinking.
0:00:56 > 0:00:59If the entire cargo ends up in the ocean, that would effectively
0:00:59 > 0:01:03be in the top ten oil spills worldwide, ever.
0:01:03 > 0:01:07So it has a huge potential for environmental damage.
0:01:07 > 0:01:10Major oil spills from tankers are becoming less common.
0:01:10 > 0:01:13One of the most serious from recent years was the sinking
0:01:13 > 0:01:18of the Prestige off the coast of Spain in 2002.
0:01:18 > 0:01:20More than 60,000 tonnes of oil
0:01:20 > 0:01:25came ashore over a long stretch of coastline.
0:01:25 > 0:01:27Specialist clean-up vessels have been sent to the scene
0:01:27 > 0:01:29of the tanker fire.
0:01:29 > 0:01:31There were 32 crew on board.
0:01:31 > 0:01:33One of them has died.
0:01:33 > 0:01:35The rest are missing.
0:01:35 > 0:01:39Rescuers trying to reach the site are being pushed back by a large oil
0:01:39 > 0:01:48slick and thick clouds of smoke, but are continuing their efforts.
0:01:48 > 0:01:50Tonight's FA Cup game between Brighton and Crystal Palace
0:01:50 > 0:01:54will be the first time Video Assistant Referee technology
0:01:54 > 0:01:57is used in a competitive club match in England.
0:01:57 > 0:02:03It's called VAR for short - and basically means
0:02:03 > 0:02:06a referee will be able to watch back tackles and goals on a screen
0:02:06 > 0:02:09by the side of the pitch if he's not quite sure what happened.
0:02:09 > 0:02:13The International Football Association has agreed to a trial
0:02:13 > 0:02:18of the technology.
0:02:18 > 0:02:21Thank you, that's a yellow card.
0:02:21 > 0:02:23We'll be watching to see how it goes.
0:02:23 > 0:02:25Next, how clean is the air we're breathing?
0:02:25 > 0:02:27Research by the World Health Organisation says air quality
0:02:27 > 0:02:29in more than 44 UK cities isn't good enough.
0:02:29 > 0:02:31And one girl wants to try and change that.
0:02:31 > 0:02:32I've been to meet her.
0:02:32 > 0:02:35Air pollution isn't always easy to see.
0:02:35 > 0:02:39It's caused by burning fossil fuels, things like coal and oil
0:02:39 > 0:02:42that we use to make heat, electricity and to fuel
0:02:42 > 0:02:45cars and lorries.
0:02:45 > 0:02:48Hadeel goes to school in a part of London with one of the highest
0:02:48 > 0:02:52levels of air pollution in the country.
0:02:52 > 0:02:54This road is really busy with trucks, vans, cars,
0:02:54 > 0:02:59buses, you name it.
0:02:59 > 0:03:02Using this special camera, we can see some of the harmful
0:03:02 > 0:03:05gases in the air.
0:03:05 > 0:03:08Look as it drives off and look at the cars next to it as well.
0:03:08 > 0:03:10When you put it in normal mode...
0:03:10 > 0:03:11Nothing.
0:03:11 > 0:03:12You can't see anything.
0:03:12 > 0:03:15But what are we actually looking at?
0:03:15 > 0:03:19This lab measures quality of air from all over the UK.
0:03:19 > 0:03:21I can see here that you've got pollution coming out
0:03:21 > 0:03:23of the exhausts of vehicles.
0:03:23 > 0:03:26That is mainly going to be nitrogen dioxide and very small particles,
0:03:26 > 0:03:28both of which can be damaging to health.
0:03:28 > 0:03:31It's not a worry for most of us who are healthy,
0:03:31 > 0:03:35but if you have an existing problem with your breathing,
0:03:35 > 0:03:38like many old people do, or if you have asthma,
0:03:38 > 0:03:40both of those things can be affected by air pollution.
0:03:40 > 0:03:43The Mayor of London, Sadiq Khan, says the problem is unacceptable,
0:03:43 > 0:03:45and has promised to help get pollution levels down
0:03:45 > 0:03:51to the World Health Organisation standards by 2030.
0:03:51 > 0:03:54But Hadeel wants more done more quickly.
0:03:54 > 0:03:57I am writing this letter to the London Mayor, Sadiq Khan,
0:03:57 > 0:04:01to tell him how unhappy I am about the air pollution in London.
0:04:01 > 0:04:03I wrote two proposals.
0:04:03 > 0:04:06The first one is to see more electric cars on the road.
0:04:06 > 0:04:11The second one is to get factories to stop using harmful chemicals.
0:04:11 > 0:04:14She is sending it to City Hall, where the Mayor of London works.
0:04:14 > 0:04:18Newsround contacted Sadiq Khan about Hadeel's concerns,
0:04:18 > 0:04:20and his office told us that the Mayor is doing
0:04:20 > 0:04:22everything in his power
0:04:22 > 0:04:27to tackle London's toxic air, creating 12 low emission bus zones,
0:04:27 > 0:04:29phasing out diesel taxis, checking the quality of air around
0:04:29 > 0:04:34schools and alerting people when air quality falls below
0:04:34 > 0:04:36a certain standard.
0:04:36 > 0:04:39The Government has promised to give £3.5 million to help
0:04:39 > 0:04:44improve air quality.
0:04:44 > 0:04:45That's it from us.
0:04:45 > 0:04:50Ricky's here in the morning.
0:04:50 > 0:04:55Make sure you head online for the rest of the day's stories. And why
0:04:55 > 0:05:00not try out our quiz of the week? See you tomorrow.
