The Inquiry

Rewilding, or letting nature take care of itself, can restore stability to damaged ecosystem components which support life on earth, like fungi, bacteria, vegetation, insects and animals.
But there's now a wider discussion to discover what it’s capable of on a wider scale.
International agreements for reducing the impact of climate change tend to set global targets.
However, individual governments decide how to work towards meeting those goals at a national level.
Some rewilding initiatives improve biodiversity, but it can have negative impacts too.
This week on The Inquiry, we’re asking ‘How can rewilding help combat climate change?’

In February, Polish Prime Minister Donald Tusk posted a social media video celebrating new figures from the International Monetary Fund suggesting that the average person in Poland now has slightly more spending power than the average person in Spain, the European Union’s fourth largest economy.
It’s a symbolic milestone for a country that emerged from communism just over three decades ago and once struggled with hyperinflation and economic upheaval. In 2025, Poland’s economy also passed the trillion-dollar mark, putting it in an elite group of just 20 countries globally.
Investment from across the EU has helped drive growth. But can Poland keep its edge as labour shortages grow and the war in neighbouring Ukraine continues to shape the region?
This week on The Inquiry, Tanya Beckett asks: Why is Poland’s economy booming?

Half a million people are in Spain without official permission.
They come mainly from Colombia, Peru, Honduras, Paraguay, and Argentina. It’s thought that most outstay their work, student, or tourist visas.
An amnesty to grant them legal status to remain and work is due to start within weeks.
It's a very different approach from most other countries in Europe that have been tightening controls on migration.
The prime minister has admitted “Some say we've gone too far, that we're going against the current”.
Opposition parties argue that this policy puts pressure on public services.
This week on The Inquiry, we’re asking: “How will Spain’s migrant amnesty work?”

Control of critical minerals is becoming a source of geopolitical tension. They are essential to modern technology and industries around the world, and China currently dominates the mining and processing industry.
As demand grows, governments in the United States and elsewhere are looking at ways to reduce their reliance on Chinese supply chains. That means investing in new mines and processing facilities even though they are expensive and environmentally toxic.
Ultimately, the US and EU have a goal of diversifying the control of these lucrative elements.
This week on The Inquiry, Tanya Beckett explores whether the rest of the world can catch up with China in the race for rare earths.

The 2026 men’s football World Cup will be the biggest ever staged. For the first time, 48 teams will compete, playing more than 100 matches across North America.
But the expanded scale comes at a cost. Ticket prices are far higher than at the last World Cup in Qatar. With matches also spread across the US, Mexico and Canada, attending the tournament is becoming unaffordable for many global fans.
FIFA says higher revenues will be reinvested to grow the game worldwide and has released some lower-priced tickets for dedicated supporters, but some fan groups say this isn’t going far enough.
This week on The Inquiry, we’re asking: Is the 2026 World Cup an own goal?
