0:00:05 > 0:00:07Hi, I'm Martin, it's Friday afternoon and this is Newsround.
0:00:07 > 0:00:10Here's what's coming up on the show.
0:00:10 > 0:00:16It's finals weekend for The Voice and we've got the lowdown for you.
0:00:16 > 0:00:25And could this be the world's most famous tortoise?
0:00:26 > 0:00:31But first, today could be a big day in the fight to save elephants.
0:00:31 > 0:00:34Over the last seven years the number of the animals in the wild
0:00:34 > 0:00:34has dropped by a third because of poaching.
0:00:36 > 0:00:38And it's all because their tusks are made of ivory.
0:00:38 > 0:00:40Here's Ricky with more.
0:00:40 > 0:00:43Thousands of shops across China sell ornaments like this
0:00:43 > 0:00:47which are made out of ivory.
0:00:47 > 0:00:52It's big business here and the items are worth a lot of money.
0:00:52 > 0:00:54Ivory comes from the tusks of elephants, and in Africa
0:00:54 > 0:01:00many of the animals are illegally hunted for that ivory.
0:01:00 > 0:01:03Pressure has been put on China for years to end its part
0:01:03 > 0:01:06in the ivory trade.
0:01:06 > 0:01:10And today almost half the factories and shops that sell ivory in China
0:01:10 > 0:01:10have been shut down.
0:01:10 > 0:01:17And the rest will be closed by the end of the year.
0:01:17 > 0:01:19China is the country with the world's largest ivory market.
0:01:19 > 0:01:26That's where we see the greatest demand.
0:01:26 > 0:01:29So this change is going make a real difference for African elephants
0:01:29 > 0:01:33because if we can reduce that demand all law abiding citizens will not
0:01:33 > 0:01:34be buying the ivory.
0:01:34 > 0:01:37This move won't totally end the problem as lots of ivory
0:01:37 > 0:01:41is bought and sold illegally, which is much harder to stop.
0:01:41 > 0:01:46But conservationists are glad that China is closing its ivory shops
0:01:46 > 0:01:49and hopes it will mean less is bought and sold in the country,
0:01:49 > 0:01:51saving the lives of thousands of elephants.
0:01:51 > 0:01:54If you want any more information on the ivory trade or animal
0:01:54 > 0:01:56poaching then head online and check out our guide.
0:01:56 > 0:01:59That's also where you can find our special programme showing
0:01:59 > 0:02:03how this issue is facing Rhino as well.
0:02:03 > 0:02:09Next, this rocket launch behind me is no ordinary lift-off.
0:02:09 > 0:02:13It's the first time a rocket's headed back into space after having
0:02:13 > 0:02:15been there before.
0:02:15 > 0:02:18Normally rocket parts are used only once and then scrapped or destroyed
0:02:18 > 0:02:19when it lands back on Earth.
0:02:19 > 0:02:22But American company SpaceX has found a way of landing rocket parts
0:02:22 > 0:02:25safely back on Earth and then re-using them to head
0:02:25 > 0:02:26back into space.
0:02:26 > 0:02:28It's hoped this will help make rocket launches a lot
0:02:28 > 0:02:30cheaper than before.
0:02:30 > 0:02:33Next, for almost three months we've been watching singers battle it out
0:02:33 > 0:02:35to be crowned the winner of The Voice UK.
0:02:35 > 0:02:37This weekend four finalists will be on that stage
0:02:37 > 0:02:38fighting for your votes.
0:02:38 > 0:02:45Ricky's been checking out the competition.
0:02:45 > 0:02:46The Voice.
0:02:46 > 0:02:50It may have switched channels.
0:02:50 > 0:02:58But that hasn't stopped the talent from shining through.
0:02:58 > 0:03:00This year, new coaches were thrown into the mix.
0:03:00 > 0:03:03Jennifer Hudson, Tom came back and this guy - Gavin Rossdale.
0:03:03 > 0:03:04Poor thing.
0:03:04 > 0:03:10he's the only one without a contestant in this weekend's final.
0:03:10 > 0:03:15So let's meet 2017's finalists.
0:03:15 > 0:03:25For Team JHud, Jamie and Mo.
0:03:25 > 0:03:35Tom Jones has this duo called Into the Ark - clever name!
0:03:36 > 0:03:41And Michelle will be singing her heart out for will-i-am.
0:03:41 > 0:03:43So can the sixth series of The Voice deliver a superstar?
0:03:43 > 0:03:45It's not going to be easy.
0:03:45 > 0:03:47Recognise any of these previous winners?
0:03:47 > 0:03:48Well, maybe not.
0:03:48 > 0:03:50This year ITV say they're doing things differently.
0:03:50 > 0:03:52The winner won't release a new single straight away.
0:03:52 > 0:03:55Instead a recording of their final performance will be available
0:03:55 > 0:04:02to stream and download.
0:04:02 > 0:04:05Then whoever wins the public vote will head into the studio to work
0:04:05 > 0:04:08with top producers and release an album a few weeks later.
0:04:08 > 0:04:11Next to a snake drinking a bottle of water.
0:04:11 > 0:04:16That's right!
0:04:16 > 0:04:19India has been hit with a serious drought, which means that there's
0:04:19 > 0:04:21been no rain for quite a while and there
0:04:21 > 0:04:23isn't a lot of water.
0:04:23 > 0:04:25And as you can see this Cobra is pretty thirssssssty!
0:04:25 > 0:04:30Look he's almost finished the whole bottle!
0:04:30 > 0:04:32Finally, from one reptile to another, and this one is possibly
0:04:32 > 0:04:34the most famous tortoise in the world!
0:04:34 > 0:04:37This cute little fella is Bubba and he's is a major internet star -
0:04:37 > 0:04:40with views of the video racking up around 60 million.
0:04:40 > 0:04:41Wow!
0:04:41 > 0:04:43He's not exactly a slow tortoise, is he?
0:04:43 > 0:04:46Look at him go!
0:04:46 > 0:04:51His family say the thing he enjoys is being out around people,
0:04:51 > 0:04:53That's all from me.
0:04:53 > 0:04:54Newsround's back tomorrow morning with Leah.
