European glass eels are worth a fortune in East Asia, where they're regarded as a delicacy in restaurants in China and Japan. But the lucrative smuggling trade from Europe to Asia is contributing to their status as an endangered species. Ed Butler tries some eel in a restaurant in Japan while UN researcher Florian Stein describes the scale of the smuggling. Andrew Kerr, chairman and founder of Sustainable Eel Group, explains the risks to the species in Europe.

Donald Trump has threatened to pull the US out of the global postal system, after receiving a letter from the inventor of the "Mighty Mug".

Jayme Smaldone tells Manuela Saragosa how he was prompted to write the letter by the inexplicably low prices that Chinese knock-offs of his product were able to charge on online retail platforms in the US.

It all boiled down to the arcane system of international postal charges set by the Universal Postal Union way back in the 1800s, as Washington DC-based lawyer Jim Campbell explains. And according to Gary Huang of the American Chamber of Commerce in Shanghai, some Chinese businesses are profiting enormously.

It's easy for anyone, from criminals to stalkers, to dig up your personal information online. So is it even possible to disappear in our digital world?

Manuela Saragosa is somewhat shocked by Tony McChrystal of data security firm ReputationDefender, when he reveals the personal details he discovered about her from a cursory search on his mobile phone shortly before she interviewed him.

Silkie Carlo of pro-privacy lobby group Big Brother Watch explains why she thinks the big social media companies and online retailers need to end the implicit deal whereby they offer us free services in return for the ability to track and monetise our data.

Plus Frank Ahearn explains how his job used to be trying to trace individuals who want to disappear, such as those who have skipped bail. Today he helps clients disappear online, to escape stalkers or dangerous former business associates. He says it's not that hard to throw people off your digital trail.

Are "voluntourists" - foreigners coming to do well-meaning voluntary work - actually doing more harm than good at developing world orphanages?

Manuela Saragosa speaks to one who says she saw the light. Pippa Biddle travelled to Tanzania to help do construction work at an orphanage. But she soon realised that the shoddy work she and her fellow American students were doing was creating more work for the people they were supposedly helping, and the whole project was really designed for their own benefit.

But the harm goes further than that, as James Sutherland, who works in Cambodia for the child welfare organisation Friends International, explains. Voluntourism creates a demand for an industry of fake orphanages trafficking in children who are not even orphans.

Could the European Parliament elections plus Brexit next year together provide the death knell for the European federalist dream? Populist parties from the far right and far left across Europe hope to take control of the heart of Europe at the 2019 elections.

Manuela Saragosa reports from the parliamentary building in Brussels, in the last of our five programmes this week looking at the future of Europe. She meets two Brits whose careers were thrown into turmoil by the Brexit referendum in 2016. Simone Howse has been told that she can keep her job as an interpreter in the plenary chamber even after her home country leaves the EU. But MEP Catherine Bearder, along with her 72 compatriots, will be turfed out when her current term ends in July.

But what fears do the they and others in Brussels have of a looming populist takeover of parliament? What will it mean for the future direction of the European project? Is it the end of federalism? Someone who hopes so is the pro-European but anti-federalist Czech MEP Jan Zahradil.

The populist government in Warsaw is accused of picking fights with the EU and dividing the public against each other. Ed Butler reports live from the city of Poznan, where some residents tell him that they no longer discuss politics at home because it has become such a divisive topic within their families.

In a post-Brexit world, few Poles want to follow the UK in leaving the EU, and most agree that their country has benefited enormously since joining in 2004. Ed visits the Solaris bus manufacturing plant, where director Mateusz Figaszewski explains how his company can now easily export to the rest of the Continent. But many Poles feel that Europe is not treating their country fairly, among them are Zbigniew Czerwinski, the deputy head of the ruling PIS party in the Poznan region.

Is Brexit boosting a bust-up with Brussels? Gianmarco Senna, is a ruling Lega Party counsellor with the regional Lombardy authority. He told Manuela Saragosa he thinks Brexit is marvellous. But while Italy is unlikely to follow in the UK's footsteps, Manuela is in Milan looking at how Brexit might help the Italian Government extract what it wants from the EU – more money to spend on helping fix the economy. And Professor Francesco Giavazzi of Bocconi University says there is a danger the country could split in two – the north and the south.

President Emmanuel Macron has big plans to shape the future of the European Union. It looks like a multi-speed, multi-lane motorway. Is this really the answer to those who are tiring of the European project? And will trouble at home mean he struggles with his plans anyway? Rob Young speaks to President Macron’s economic adviser, Philippe Aghion who tells him about President Macron's plans to renew, some say to save, the European Union. He also speaks to former Socialist Presidential candidate and a current French ambassador, Ségolène Royal, about what many see as the biggest threat the EU faces - nationalism. Plus he visits a factory just outside Paris to find out why they support domestic reforms to the French economy.

How do German citizens feel about the future of the world’s largest trading bloc? Ed Butler visits PSM Protech, a specialist engineering firm in Bavaria where he speaks to its owner Irene Wagner about what the EU means to her company plus he asks Volker Wieland, an economics professor at a Frankfurt University and one of Germany’s five key economic advisors, the so-called Wise Men, what the threats to the EU are.
