Coral reefs are an irreplaceable environmental and economic treasure, in need of help

"Losing the world's coral reefs would be like burning every Impressionist painting - you won't get them back." A new exhibiton at the Natural History Museum shows just what a tragedy these natural wonders' loss would be.

When we hear the words "coral reef" we probably reminiscence on its collage of beauty, and feel nostalgic about Finding Nemo, but that’s probably as far as most people's knowledge goes. Yet despite occupying only about 0.1 per cent of the ocean’s floor, they provide life for at least a quarter of all marine species  and with rareness comes fragility. Human interferences such as overfishing, coral bleaching, pollution and climate change have damaged coral reef ecosystems, and many of them are now holding on for dear life.

By 2050, practically all of the world’s coral reefs will be seriously endangered. The Caribbean reefs, for example, have already lost 80 per cent of its coral cover since the 1970s, mainly due to the overfishing of the fish which eat algae that grows on it, as well as a disease that wiped out algae-eating sea urchins – causing the complete off-balance in the coral:algae ratio. Coral and photosynthesising algae are meant to live in symbiotic harmony when the water temperature is just right, but a rise in global temperatures stresses the algae; they get fed up and start to leave the coral in a process called "coral bleaching". The result is that the corals lose their algae, and without the algae they start to die. 

There are around 800 species of coral worldwide, and some have developed extreme survival tactics, like dissolving neighbouring corals with digestive toxins. But this isn't enough, and like all ecosystems, the damage caused to the coral reefs will have a domino effect throughout the world's oceans, and on land - like people living in countries like the Philippines and Haiti, two impoverished places which depend on the reefs for both food and tourism revenue.

To try to kick against public ignorance of just how important coral reefs are to us, the the Natural History Museum has curated a new exhibition about them. "This exhibition helps us to understand and predict the effect of human impact and climate change on our oceans, one of the biggest challenges facing our natural world today," said Sir Michael Dixon, the NMH's director ahead of its opening. "Coral reefs [...] are being studied every day here at the museum."

The exhibition is simple, spacious but effective. You walk in feeling as those you’ve been immersed in water, and there are geometrically-accurate structures of corals dotted around the space to create that "under the sea" illusion (though they're made from fresh plywood, the pungent smell of which may sometimes slap you back to reality).

Speaking to the NS at the press opening, Ove Hoegh-Guldberg from the University of Queensland spoke about why coral reefs are important, and the dangerous consequences of not having them around anymore:

Coral reefs are important for a number of reasons. Up front they are an enormously beautiful and diverse system – the most diverse ecosystem on the planet, aside from the rainforests. When you look at their contribution, they have generated trillions of dollars to economies across the planet. But what’s important is that there are about 500,000 people with very little means who live along coastlines and look to coral reefs for their daily meals and income. And those 500,000 people are extremely vulnerable. If we start to lose productivity of coral reefs and fisheries disappear, those people become even more impoverished.

It's an informative exhibition  and here are seven highlights:

1) It has six corals collected by Charles Darwin during his HS Beagle from 1831 to 1886  and even better, it's got the illustrations from his first scientific study, on the formation of coral reefs.

Darwin's notebook.

2) A giant Turbinaria coral – a massive, one-metre-long specimen, the many layers of which would have been a safe haven for many sea species.

3) A giant clam – the biggest of all living bivalves, and weighs as much as 300 bags of sugar. It's currently under threat of extinction as a result of overfishing.

4) A giant grouper – about the size of a large motorcycle, it’s the largest bony fish living in the Great Barrier Reef. But don’t be deceived by its size, as it doesn’t eat humans and is in real threat of extinction throughout the Indo-Pacific region due to overfishing.

A mighty, giant grouper fish.

5) A sea fan – a fragile lace-like structure that helps filter food out of the water. It’s also home to seahorses and nudibranchs.

6) Gorgeous 180 degree panoramic imagery of several reefs in a chamber of circular screens.

The immersive reef chamber.

7) A hundred real-life fish and 26 species of coral, making up a four-tonne aquarium. (And, of course, I tried to count up all the Nemos and Dorys I could find.)

"Losing the coral reefs would be like taking all the Impressionist pictures in the world and burning them, because you won’t get them back," said Hoegh-Guldberg. "Once you’ve lost them it’s a tragedy." On this evidence, it's clear why.

Coral Reefs: Secret Cities of the Sea will be opened to the public on 27 March – 13 September 2015, 10.00 – 17.50. All photos by the author unless otherwise credited.

A year in my life as a Brexit bargaining chip

After Brexit, like many other EU citizens in Britain, I spent a year not knowing what my future held. Here's what that was like.

I moved back to the UK in January 2016. I like to say “move back”, because that’s how it feels – I loved living in London so much during my Erasmus year that I always intended to come work here after graduation. 

I am French, and a journalist, and live in north London. I refer to the UK as “home”. By all appearances, in January 2016 I am part of what budding Brexiteers call the “liberal elite”, even though I rent a single room and my most expensive possession after my laptop is a teapot.

But by June, I have been given a new label. I am now one of the 3 million “EU citizens in the UK”. As Britain heads toward turbulent negotiations to leave the European Union, following a referendum in which I did not have a vote, I have become a “bargaining chip”. 

This is my account of that year.

April 2016

Moving back includes chores such as getting a UK phone number, a National Insurance number and opening a bank account – three tasks that go even smoother that I thought they would. For the bank account, I have been advised to go to Lloyds Bank, which makes it “easy for Europeans”. (A thread on Twitter recently proved it also is more inclined to help refugees than other banks.)

I also eagerly register to vote – another right of mine in the UK under EU rules, for local and European elections. And I am excited: I will have a vote in the London mayoral election.

I closely follow the referendum campaign. “Vote Remain” signs and stickers are omnipresent in my  neighbourhood.  I feel reassured. So do the other EU nationals quietly passing me in the street. “I don't recall seeing any Leave Campaign. It made me think it would be an easy win,” echoes Tiago Gomes, 27, a Portuguese musician.

In the pub, I get into a testy exchange with an acquaintance who holds French and British passports and is proudly campaigning for Leave. I struggle to understand why. Maybe, just like Ukip leader Nigel Farage, he knows he has a way out, if it all goes to shit.

Worried that people could wrongly see me as a Brexiteer because of my Union Jack Converses, I put a “I’m IN” sticker on each roundel.

May 2016

I vote in the London mayoral election. I have voted many times in France, but this is different – I am almost a Brit! I even take a happy selfie with my polling card, like a proud 18 year-old.

This turns out to be the only UK election I will ever have a vote in, as a friend will note a few months later.

June 2016

Jo Cox MP is murdered on the streets of her constituency. I report on the murder all afternoon and when I get the tube home, I feel shaken. A Leave supporter enters the tube carriage with an England flag. I want to ask him: "Do you even know what happened?" But I say nothing.

The violent turn taken by the campaign is felt in London, too. Samir Dwesar, a 27-year-old parliamentary assistant, remembers the abuse he suffered while campaigning for Remain: “I was called a p**i, and told to go back to ‘your f’ing country'.” Samir is British and has lived all his life in Croydon, South London.

Yet I am hopeful on 23 June 2016. I blow up “I’m IN” balloons, taste EU referendum cupcakes from my local bakery. I’m living history.

And it is history. I doubt anyone in Britain, and especially the country’s EU citizens, will forget the nightmarish morning of 24 June 2016. My heart sinks as I read the BBC news alert informing me I am no longer home – not really. On my wall, a poster of the Private Eye cover “What Britain will look like after Brexit”, which I found hilarious in April, looks like a doomed omen.

The mood is low among all Europeans. For Nassia Matsa, 27, a Greek woman from Athens who has lived in London for 9 years, it is even worse: 24 June marks her birthday. “Nigel and Boris ruined my birthday,” she says.

At least in London we are not alone. I discover many Brits identify as European. When I finally leave my house, my neighbourhood is still plastered IN signs and EU flags. “I found myself offering support to my British friends,” says Matsa. “Were talking about Brexit with an Italian, Swiss, Croatian, French and me, and all of us Europeans were comforting a Londoner who was ready to cry.”

July-August 2016

I go to France for a summer holiday. Everyone keeps asking what my situation will be in the UK after Brexit. My answer is always the same, and still hasn’t changed: I have no idea. My dad spends months repeating that Brexit will not happen: “They’ll realise it’s a mistake.” (They don’t.)

Bad adverts with Brexit puns bloom on the Tube. "We're Out," proclaims one for a city lifestyle app. I don’t laugh. But at least I don't have any Facebook friend boasting about Brexit. Mikael David Levin, a 24-year-old Italian who has lived in London for 16 years, does. "Their statuses frustrate and irritate me," he says. "They do not know how 'lucky' they are to be born in the UK."

After David Cameron’s resignation, the Tory leadership election and Theresa May’s premiership, the discussion focuses on when to pull the trigger, and what to do with people like us in the meantime. We are now, officially, bargaining chips.

September 2016

I start flying with my passport when I visit my family in France, even though I know my French ID is still valid until Britain officially leaves. At Stansted airport, the limited life expectancy of the “EU only” line makes me gloomy. Alex Roszkowski, a 27-year-old Polish-American who has lived in London for a year and a half, tells me he may now carry both his passports on every trip, as well as “copies of [his] lease, numerous old envelopes with [his] name and address, [his] business card".

Those EU citizens arriving in the UK have surreal experiences too. Joseph Sotinel, 28, who moved to London from Paris in September, encounters a bank official, who tells him: “Thanks for coming to the UK, you are still welcome no matter what.”

“It was as if I had done something heroic,” he says. “It was absurd.”

October 2016

Registering all EU citizens in the UK could take 140 years, according to a cheery statistic.

We are seeking an early deal to secure the rights of EU citizens, says the British government. Companies employing EU workers must provide a list of their employees, says the British government. Companies employing EU workers won’t have to provide a list of their employees, says the British government. EU citizens will need a “form of ID” in post-Brexit UK, says the British government.  EU citizens must be prepared to leave, says the British government.

Literally no one knows what will happen to EU citizens.

November- December 2016

EU nationals who have decided to apply to permanent residency or British citizenship start receiving letters urging them to leave the country. I fear mine could follow and think about it every time I get post. I read an article advising EU citizens to collect proof of living in the UK. As I am a lodger currently working freelance, I start keeping every single one of my shopping receipts in a box, and consider asking British friends for reference letters.

Matt Bock [unrelated to this journalist], a German freelance renewable energy project manager, worries about how to provide documentation showing he was living in the UK before Brexit too: “I don’t have an employer, I am outside the UK for a large amount of time for work, I am a freelancer largely paid by my own German company, I don’t have private health insurance, I am not married and I haven’t even been here for the prerequisite 5 years.”" He has chosen not to apply to right to remain because his chances of success are "remote", and says he is "ready to leave if need be."

As I, like Matt and many EU citizens, start thinking about moving back home, others rush to move to the UK. Alexandra Ibrová, 26, a Czech PhD student, moves to London on 28 December, worried she could not get a National Insurance number after 15 March. “I was trying to get the appointment before that date because it is actually the only official document that proves that you have been living here before the cut off date,” she says.

January- February 2017

Gina Miller’s legal challenge forces the government’s Brexit bill to go to a vote in Parliament. I am hopeful, for about five minutes, that the Labour MP Harriet Harman’s amendment to secure my rights has got a chance. It doesn’t. I complain about Labour leader Jeremy Corbyn’s three-line whip to my local Labour councillors during their Sunday canvassing. “As a traditionally left-wing voter, I'm more angry with Corbyn's Labour than with the Tories,” echoes Marta Maria Casetti, 39, from Italy, in London since 2006.

March 2017

The day before the triggering or Article 50, the Haringey LibDems send me a letter in “support” of EU nationals. I am now a bargaining chip and a stat on a micro-targeting list.

On 29 March, Theresa May officially begins the Brexit negotiations, even though 2017 is the worst possible time to leave the EU. It has almost been a year that 3 million people living in the UK have been left in limbo.

I don’t own a house or have children at school in the UK. Many EU citizens do – they have built their family life in this country, and now fear they may lose it all overnight.

Adriana Bruni, 44, an Italian who married an Englishman and has lived in Chelmsford for six years, says her family would not exist without the European Union: “From today [29 March], a family like mine will never be formed in the same way again.” Bianca Ford Epskamp, a Dutch national and school governor who has lived Dorset since 2001, adds: “Both my children are born here, go to school here, have made friends. I've always been employed, contributed, paid taxes, do voluntary things. Morally, it’s draining.”

Elena Paolini, 51, an Italian translator married to Brit who has lived in London for 27 years, says she doesn’t believe EU nationals will be deported, but she is concerned about her access to the NHS, pensions or bank accounts. She asks out loud the question that has been floating in all our minds for months: “Will I be considered a second rate citizen?”

As for me, I used to say I wanted to be British. I don't say that any more.

Update on 23 June 2017

Last night, Theresa May told EU leaders in Brussels the UK government would offer the same rights as Britons to EU citizens who arrived "lawfully" before Brexit. I can't help but think that it took a year to guarantee rights me, and the other 3 million, already had and took for granted up until 23 June last year.
