OMG I Thought You Were Dead!

I shouted with euphoric joy through my regulator, 20 feet underwater. I can only imagine how wide my eyes were. It must have been difficult to discern between an expression of delighted surprise and a textbook example of wide-eyed diver panic. My eyes were transfixed on an old friend with a funny name whom I hadn't laid eyes on in years. I had heard he was dead—or at least gravely ill. But there in front of me, larger than life, vibrant and embracing the sun, my friend was very much alive and healthy, clearly enjoying the good life in Cuba.

Several years earlier, I joined an expedition to explore a corner of the Gulf of Mexico I had only heard about from colleagues: The magnificent coral reef ecosystem of Veracruz, Mexico. Seated inside the DeepRover submersible with great anticipation for a vibrant reef that lay below me, I was lowered from the deck of a Mexican Navy ship into the warm blue waters below and radioed the ship that I was going to begin my descent.

As the reef came into view, my eyes seemed to betray me. The rich colors of the coral reef were absent. So were the fish. Where a once-magnificent coral reef had stood less than a decade earlier, only a massive skeleton remained, now covered with algae and little else. Flying the sub between massive canyon walls built over millennia by once-thriving corals, the scene was reminiscent of World War II newsreels depicting Europe's bombed-out cities, their former glory evidenced only by the lifeless shells of long-abandoned buildings.

I had seen this before. The reefs I had so delighted in as a teenager in the Florida Keys are unrecognizable today. In the Lower Keys, live coral is estimated to be only 20 percent of what it was in the early seventies when I first dove there. Was this scene at Veracruz a mournful glimpse into the future of Caribbean coral reefs?

A major report released earlier this year from the Global Coral Reef Monitoring Network and International Union for the Conservation of Nature (IUCN) puts it clearly and bluntly: Without swift and meaningful action, “Caribbean coral reefs and their associated resources will virtually disappear within just a few decades…" The report is the most comprehensive to date, compiling a record 35,000 quantitative reef surveys from 1969 to 2012 across 90 locations in 34 countries.

The report reveals an average decline of coral cover in the Caribbean of more than 50 percent since 1970, but the overall decline, which likely began several decades earlier, is even higher. Caribbean corals are dying from a lethal mix of slow-motion insults, including fueling the growth of algae by nutrient pollution, eliminating the fish that graze on algae due to overfishing, and bathing corals in hotter and hotter water due to climate change, to name a few.

Statistics like these make it easy for one to abandon hope. Perhaps I had, too. But then I found myself yelling through my regulator, reunited at last with my long-lost friend. Most folks call him, “Elkhorn," but his scientific name is Acropora palmata: Elkhorn coral. Elkhorn coral is perhaps the Caribbean's most iconic coral species and one of the most important reef-building species. Sadly, elkhorn is now the poster child of Caribbean coral's demise. The National Oceanic and Atmospheric Administration (NOAA) estimates that elkhorn is now 95 percent extinct from Caribbean waters, and it is now listed on U.S. Endangered Species List.

I knew from data and photos taken by colleagues that such corals flourished in Cuba. And on previous expeditions, I had even glimpsed small patches of elkhorn, clinging to reef crests, standing tall before the breaking turquoise waves. But in my wide-eyed encounter, I was breathless. I beheld not just a small patch of healthy coral. I saw stand after stand—a forest of glorious, healthy mustard-brown elkhorn, as far as my eyes could see along this part of Cuba's northern coast, just 90 miles south of the decimated reefs of the Florida Keys.

Yet this was nothing compared to what I would see just a few months later. At the urging of my Cuban colleagues, I visited an archipelago 50 miles off Cuba's southern coast, named "Gardens of the Queen" by Christopher Columbus. In the fading sunlight I beheld magnificent stands of healthy elkhorn coral, impossibly packed full of grunts, snappers and angelfish seeking refuge for the evening. I later learned I had seen just a tiny fraction of a barrier reef of elkhorn that continues for more than 30 miles along the archipelago!

Elkhorn and the other corals here show virtually no signs of the diseases that have decimated reefs throughout the Caribbean. It is the healthiest Caribbean marine ecosystem I have ever seen, abundant with sharks, goliath groupers, sea turtles and many other imperiled species.

Cuba's Gardens of the Queen is the country's first marine protected area (MPA) and, at nearly 1,000 square kilometers, the largest fully-protected MPA in the Caribbean. Cuba has made a national commitment to protecting 25 percent of its waters, a staggering, world-leading figure, especially as compared to the worldwide average of 1 percent.

Today, I am filled with hope. If we can study this living laboratory to unlock the mysteries of what is keeping the coral reef ecosystems in Gardens of the Queen so healthy and resilient, we can gain insights that can guide our hand to restore coral reef ecosystems throughout the Caribbean. Working with our Cuban colleagues, we are preparing an international scientific workshop in the coming year with this very purpose, to learn from this living time machine, one of the last natural coral reef laboratories, to understand what a healthy coral reef ecosystem is supposed to look like and how we can best protect it.

I am hopeful that a spirited collaboration with Cuba helps advance international efforts in restoring the beloved natural heritage of the Caribbean. And I hope that in the not too distant future, we all have a chance to hear underwater shouts of joy.

Against All Odds, Mountain Gorilla Numbers Are on the Rise

By Jason Bittel

The news coming out of East Africa's Virunga Mountains these days would have made the late (and legendary) conservationist Dian Fossey very happy. According to the most recent census, the mountain gorillas introduced to the world in Gorillas in the Mist, Fossey's book and the film about her work, have grown their ranks from 480 animals in 2010 to 604 as of June 2016. Add another couple hundred apes living in scattered habitats to the south, and their population as a whole totals more than 1,000. Believe it or not, this makes the mountain gorilla subspecies the only great apes known to be increasing in number.

If Meditation Is Not Your Thing, Try a Walk in the Woods

There are times when I don't know what to do with myself.

Happiness seems like an entirely elusive state of being.
