There are a growing number of people speaking out about their decision not to have children because of climate change. They worry about the environmental impact of bringing a new person into the world. But how polluting is it to have kids? And is staying childfree a good way to limit how much carbon dioxide we put into the atmosphere?

The BBC’s Georgina Rannard talks us through some research from University College London. And researcher Johannes Ackva, from the Founder’s Pledge, brings us a study he co-wrote looking at how different lifestyle choices - including flying, driving a car and having children - impact the climate. He thinks that, as governments’ net-zero pledges really start to ramp up, emissions per person will likely go down - and this could impact how polluting it is to have babies in the future.

Plus, we hear from three people who’ve decided not to have kids: Nirupama Kondayya, and husband Vipin Nair from India now living in the UK, and a woman from the US.

For the first time, Ubisoft have released a Prince of Persia game with an option to have all the characters fully voiced in Farsi. It says it wants Prince of Persia: The Lost Crown to "depict and respect Persia and Iran". The game has great reviews and a lot of Iranian fans are very excited they’ll be able to experience it in their own language.

What does this say about culturally sensitivity in gaming?

We hear from Alireza Vasefi, an Iranian games reporter for BBC Persian Click, who’s played the series for years. He explains what the language option means to him.

We’re also joined by Kirsty Evers who wrote a study about gaming cultural stereotypes. She found that a majority of her participants wanted to see better representation.

Plus, what’s it like to help accurately map a historical place for a videogame? Renowned French archaeologist, Egyptologist and historical illustrator Jean-Claude Golvin helped do this for Assassin's Creed: Origins. He talks us through the process.

Young people seem to be moving away from Romania. In 2000, it had a population of 22.4 million people. But two decades later it had fallen to just 19.5 million - outward migration is responsible for most of that decline.

They’re mostly moving to other European countries, like the UK. Madeleine, from the What in the World team, went to a gig in London by a Romanian band called Subcarpați. While she was there, she chatted to young Romanian fans - why did they move away? And what does that mean for the country they’ve left behind?

It’s not just Romania that is seeing people move away for better work opportunities or to avoid a political climate they don’t like. Countries like Croatia have a similar situation - we hear from Baby Lasagna, a Croatian singer whose song ‘Rim Tim Tagi Dim’ is all about people leaving their home country.

Also, a dog called Bobi made news headlines last year when he was given the title of the world’s oldest dog by Guinness World Records. But some people don’t believe that he really made it to the ripe old age of 31. Whilst we don’t know yet if Bobi is going to lose his title (sadly he died not long after taking the crown) Alex from the team takes us through some other records that have turned out to be false. Including one very close to home…

It’s estimated that a garbage truck full of clothing is being sent to a landfill every second, with less than 1% recycled into new clothes. One way to stop clothes reaching landfill is reusing, repairing and recycling them. This is part of ‘circular fashion’ - where textiles already in circulation are used again and again, instead of producing new ones.

Lots of fashion brands and consumers are trying to make the fashion industry more sustainable. We hear from two projects at the forefront of this. Whitney Speke joins us from Nairobi to tell us how Africa Collect Textiles is tackling clothes waste in Africa. She also shares her views on the 30 wear challenge - which encourages consumers to wear their clothes at least 30 times.

We’re joined by Taylor Greene who works for Circ, a US-based company. Circ’s innovative recycling technology is addressing the fashion industry’s carbon footprint – which accounts for around 8% of global carbon emissions.

Plus, sustainability journalist Sophie Benson explains how apps have helped make sustainable fashion more accessible, and how it might be scaled up in the future.

Cape Verde has become the first sub-Saharan nation to be declared malaria-free in fifty years. But mosquitoes, the insects that spread the deadly disease, have started to fight back. One type of the insect has adapted to break all the rules and dodge all the measures we’ve brought in to beat them. Unlike most mosquitoes, Anopheles Stephensi, can live in urban environments potentially putting people in cities in Nigeria, Sierra Leone, Kenya, Djibouti, Ghana and more at risk.

The BBC’s Tulip Mazumdar explains the symptoms and effects of malaria. And Dorcas Wangira, our Africa Health correspondent in Kenya, talks to us about this adapted mosquito and the challenges it poses.

The Houthi, a political and military group in Yemen, have been attacking ships in the Red Sea since November. They say they’re targeting vessels headed to or owned by Israel as a way to support Palestinians in Gaza.

Not all of the ships are connected to Israel. And now the US and UK has launched military airstrikes on Houthi targets in Yemen to reduce their military capability.

So what’s happening in the Red Sea?

Frank Gardner, the BBC’s security correspondent, explains who the Houthis are and what’s motivating their attacks. And Nawal Al-Maghafi, an international correspondent for the BBC who’s reported extensively from Yemen, tells us a bit more about the group’s political strategies and how they’re framing their approach to the Israel-Gaza conflict.

As a result of the Houthi attacks, many of the world's biggest shipping companies have stopped vessels using the Red Sea route, opting for an alternative route through the Cape of Good Hope. Michael Race, a BBC Business reporter, explains how these attacks are affecting the transport and price of consumer goods.

Hundreds of people have been trying to set new world records in Ghana, with applications flying in since July 2023.

Earlier this week a Ghanaian chef, Faila Abdul-Razak, completed the longest non-stop cook-a-thon, chopping and frying for more than 227 hours. She hasn’t yet officially been given the title.

She isn’t the first to try though - last year a Nigerian chef, Hilda Baci, broke the world record, jumpstarting a trend for breaking world records in Nigeria too.

So why are there so many attempts in Ghana and Nigeria? Our reporter in Accra, Favour Nunoo, runs us through some theories.

We also chat to Afua Asantewaa - a Ghanaian who’s attempted to set the Guinness World Record for the longest singing marathon. She managed five days straight.

And William from the What in the World team demonstrates a hidden talent that definitely breaks our records! (12:00) Plus AFCON, the Africa Cup of Nations, kicks off this weekend with Ivory Coast vs Guinea-Bissau as the opening match. Teams like Morocco, Senegal and Egypt are among the favourites to win the tournament - but we find out from the BBC’s Isaac Fanin how one man used the video game Football Manager to try to give underdogs Guinea-Bissau an advantage.

The notorious leader of Ecuador’s main criminal gang escaped from prison this week - he is still missing. The country’s President declared a state of emergency and the gangs fought back, with gunmen breaking into a TV studio during a live broadcast. Separately 130 prison staff are being held hostage by inmates.

BBC Monitoring’s Rachelle Krygier, who focuses on Latin America, explains who the gangs are and how they operate from within the prisons. BBC Mundo’s Ana Maria Roura, who’s from Ecuador, talks through whether the government’s strategy of bringing in the army could work.

Also, Madeleine Drury from the What in the World team tells us about various approaches being tried in different South American countries to tackle the gangs.

More than one in five people between the ages of 16 and 24 are jobless in China according to the latest government data. But the figure could be even higher.

Millions of university graduates are struggling to find high paying jobs. So the government is encouraging them to roll up their sleeves and consider manual work in the countryside instead.

But many aren’t keen and some are ducking out of the rat race all together, sharing memes of themselves ripping up their degrees. We hear from Joy, who says that out of her class of 32, only around a third have found full-time jobs since graduating in the summer.

Laura Bicker, a BBC correspondent based in Beijing, explains what led to this point, and what might happen next.

We need precious metals to run green tech but what’s the cost of mining them?

Norway has approved commercial-scale deep-sea mining off its shores in the hunt for precious metals which are in high demand for green technologies. However, environmental scientists warn it could be devastating for marine life. Climate reporter Esme Stallard takes us through the controversial plans.

One of the metals Norway is looking for is cobalt. Currently the world’s main source of cobalt lies in the Democratic Republic of Congo (DRC), where miners toil in often poor conditions and armed conflict in the country has contributed to what the United Nations says is one of the “largest humanitarian crises in the world”.

BBC Africa’s Wedaeli Chibelushi describes the picture in the country and explains why some TikTokers are quitting vaping because of mines in the DRC.

It’s been nearly two years since Russia invaded Ukraine. Millions of people have fled the country and thousands have been killed. The fighting is still going on, with Ukraine’s leader Volodymyr Zelensky continuing to appeal for international support.

BBC Monitoring’s Russia editor, Vitaly Shevchenko, takes us through what Zelensky’s life has been like since the war began. Before becoming president in 2019, he was a comedian and even voiced Paddington Bear in the Ukrainian version of the film - how is he dealing with being in charge?

Disney’s copyright on ‘Steamboat Willie’, which features the earliest version of Mickey Mouse, expired in the US on New Year’s Day - meaning the image is in the public domain and free to use… with some caveats. So what’s next for Mickey?

Some creatives have already sprung into action. Noor Nanji, a BBC Culture reporter, tells us about an upcoming Mickey Mouse slasher movie and a video game.

We also hear from Erin Delmore, the BBC’s North America Business Correspondent and Jennifer Jenkins, a professor of intellectual property law at Duke University, about how public domain laws work. Plus we pitch some ideas of our own.
