0:00:11 > 0:00:15Hi, I'm Martin and this is your Newsround.
0:00:15 > 0:00:17First, people around the world are getting ready to witness
0:00:17 > 0:00:20a lunar extravaganza tonight.
0:00:20 > 0:00:24It's called a super blue blood moon, but what is it?
0:00:24 > 0:00:28Here's BBC Weather Presenter Simon King to explain.
0:00:28 > 0:00:31Now, apart from it being a mouthful to say, what does it actually mean?
0:00:31 > 0:00:34Well, let's start off with the super part.
0:00:34 > 0:00:37Now, the moon orbits the Earth in an ellipse,
0:00:37 > 0:00:40so that means there are occasions when the moon is closer to Earth
0:00:40 > 0:00:42than others, and we call that the perigee.
0:00:42 > 0:00:45Now, this is going to be one of the closest points the moon
0:00:45 > 0:00:49is going to take to Earth, so that means it is going to appear
0:00:49 > 0:00:51just that little bit bigger and brighter than usual.
0:00:51 > 0:00:54The blue part of it comes from the fact that every month
0:00:54 > 0:00:56we normally have a full moon, but sometimes we get two
0:00:56 > 0:01:00full moons in a month, and that is known as a blue moon.
0:01:00 > 0:01:01It won't appear blue.
0:01:01 > 0:01:04The third aspect is the blood moon.
0:01:04 > 0:01:07Because on Wednesday night, there is going to be a total lunar
0:01:07 > 0:01:10eclipse and that might make the moon turn a little bit red.
0:01:10 > 0:01:13But it's not going to be above the UK, that's actually
0:01:13 > 0:01:16going to occur on the other side of the world.
0:01:16 > 0:01:19We will still get to see a full super blue moon,
0:01:19 > 0:01:22and the best of the clear skies initially will be down towards
0:01:22 > 0:01:25the south-east of England on Wednesday evening and night.
0:01:25 > 0:01:27But then further north and west there will be some
0:01:27 > 0:01:28wintry showers moving in.
0:01:28 > 0:01:31There will still some clear spells in between that cloud,
0:01:31 > 0:01:33to get a good glimpse of the moon.
0:01:33 > 0:01:34Bye-bye.
0:01:34 > 0:01:35Next, the big question of the moment
0:01:35 > 0:01:39- how can we cut the amount of plastic we use and throw away?
0:01:39 > 0:01:41More than 8 million tonnes of it ends up in the world's
0:01:41 > 0:01:44oceans each year. That's a truckload every minute!
0:01:44 > 0:01:49So, what's the problem with plastic?
0:01:49 > 0:01:53These are trash islands in the Caribbean.
0:01:53 > 0:01:56It looks like a stretch of land but it's floating
0:01:56 > 0:02:01rubbish like plastic bags, spoons and bottles.
0:02:01 > 0:02:05They are created by currents in the ocean.
0:02:05 > 0:02:09Sadly, this is not the only place in the world where plastic
0:02:09 > 0:02:10pollution is a problem.
0:02:10 > 0:02:15Plastic is all around the planet on every shoreline,
0:02:15 > 0:02:18it's even down to the deep ocean, places we have never visited.
0:02:18 > 0:02:23We go there for the first time and our rubbish has beaten us there.
0:02:23 > 0:02:26Back in the day, milk and fizzy drinks used to be bought in glass
0:02:26 > 0:02:30bottles and food would be wrapped in paper.
0:02:30 > 0:02:32Now, plastic is in lots of things we use every day,
0:02:32 > 0:02:36and it IS really useful.
0:02:36 > 0:02:39300 million tonnes are produced each year, but 40% of that is for stuff
0:02:39 > 0:02:41we will only use once before it's thrown away,
0:02:41 > 0:02:44like straws, crisp packets, bottles and carrier bags.
0:02:44 > 0:02:49How does plastic end up in the ocean?
0:02:49 > 0:02:51Some of it is blown in, lots of it comes from rivers,
0:02:51 > 0:02:53some can come a long way.
0:02:53 > 0:02:54some escapes from ships at sea,
0:02:54 > 0:02:57Some is left by tourists on beaches.
0:02:57 > 0:03:01Some enters by the toilet.
0:03:01 > 0:03:06There's a whole range of ways that litter can get there,
0:03:06 > 0:03:10the problem is once it's there, that is where it will stay.
0:03:10 > 0:03:13Scientists are warning that within the next 30 years the amount
0:03:13 > 0:03:16of plastic in our oceans could outweigh the fish.
0:03:16 > 0:03:20Each year, 100,000 animals in the sea are killed by plastic.
0:03:20 > 0:03:23It can hurt or trap them, and they can also
0:03:23 > 0:03:26mistake it for food.
0:03:26 > 0:03:31One in three sea turtles and almost 90% of sea birds have eaten it.
0:03:31 > 0:03:34When the fish leaves the ocean and it ends up on our dinner table,
0:03:34 > 0:03:36are we eating plastic as well?
0:03:36 > 0:03:40We recently looked at fish collected locally, of 500 fish we found
0:03:40 > 0:03:44a third had small quantities of plastic in their gut.
0:03:44 > 0:03:47It's not a cause for concern for eating those fish,
0:03:47 > 0:03:49the quantities are quite small, unless we do something about it
0:03:49 > 0:03:55the quantities in fish and birds will increase.
0:03:55 > 0:03:58There are lots of groups trying to help tackle plastic pollution
0:03:58 > 0:04:00and the government is promising to do more.
0:04:00 > 0:04:03But there are ways we can all help right now.
0:04:03 > 0:04:07Here are Richard's top tips.
0:04:07 > 0:04:10Make sure you always throw your rubbish in the bin.
0:04:10 > 0:04:14If you don't need something, don't use it.
0:04:14 > 0:04:16And of course, recycle whenever you can.
0:04:16 > 0:04:18If you want to know more about
0:04:18 > 0:04:21how plastic affects our planet, head to web where we've got a full guide.
0:04:21 > 0:04:22While you're there,
0:04:22 > 0:04:26if you think black cats are the best, we want to hear from you.
0:04:26 > 0:04:28Get online.
0:04:28 > 0:04:30Finally, this guy's got his hat and gloves on
0:04:30 > 0:04:34to play a very cold concert.
0:04:34 > 0:04:36Yep, that cello has been carved from ice!
0:04:36 > 0:04:41A famous musican has been playing the chilly cello in Italy.
0:04:41 > 0:04:44He's in a special bubble that's kept really cold
0:04:44 > 0:04:47to stop the icy instrument from melting.
0:04:47 > 0:04:49It's all part of an art project,
0:04:49 > 0:04:51and the sculptor says that once the concerts are over,
0:04:51 > 0:04:56the cello will be thrown into the sea to melt.
0:04:56 > 0:05:00Newsround is back in the morning.
0:05:00 > 0:05:02 Bye.
