Finding Hope for the Isle of Youth

Columbus' ships were leaking, their provisions spoiling. It was clear that they would have to turn back. Yet, anchored off Cuba's southwestern coast near a large, mountainous pine-covered island during his second voyage, Columbus had seen enough. He was convinced Cuba was part of Asia and that return to Spain by land would be possible from the main Cuban island. He ordered each member of the crew sign an affidavit testifying to this, and their signature bound them to have their tongue cut out should they ever contradict their signed statement.

The next day, June 13, 1494, they landed on the nearby island. Columbus named it Evangelista. Over the centuries since, it bore the names Isla de Cotorras (Isle of Parrots), Isla de Tesoros (Treasure Island), Isla de Pinos (Isle of Pines), and finally, Isla de la Juventud (Isle of Youth). While Cuba claimed its sovereignty from Spain in 1898, the fate of the Isle of Pines would not be settled until more than 25 years when it officially became part of Cuba, though by then most of it was controlled by U.S. interests.

The 80,000 residents of the island often feel invisible, forgotten and disconnected from the rest of Cuba, an "island within an island." Dwarfed by the massive main island of Cuba, the world is barely aware of its very existence, despite the fact that it is the seventh largest island in the Caribbean, larger than St. Lucia, Barbados, Grenada, Bonaire, St. Croix, St. Thomas, St. John, Aruba, St. Barts, Saba, Terre-de-Haut, Isla Mujeres and Key West combined. The island has struggled for decades, with limited economic opportunities for its residents, mostly in agriculture and fishing. It has long since been forgotten as an international tourist destination.

The Cuban government has repeatedly tried to infuse life into the island. In 1978, Fidel Castro changed the name to Isle of Youth as part of an effort to bring new opportunity and meaning to the island. An initiative was launched to build a world-class international network of schools on the island, attracting students from Africa, Asia and beyond. Thirty years later, in 2008, Hurricane Gustav, with sustained winds of 155 mph, decimated the island, laying to waste the international schools and that chapter of the island's struggle.

In 2015, Ocean Doctor led an expedition of Cuban and American scientists to visit the protected waters of the Isle of Youth; most of the southern half of the island is protected, part of Cuba's massive system of protected areas. Over our 16 years of working in Cuba, we have found the country as a beacon of hope, where many coral reef ecosystems thrive in sharp contrast to the dead and dying corals elsewhere in the Caribbean.

It is estimated that 50 percent of the coral cover in the Caribbean has vanished since 1970. As we dove among the coral reefs in the Punta Frances protected area, we indeed found some of Cuba's treasured coral reefs, gleaming and healthy. But we also found reefs in stress—some bleached white, some covered in slimy green algae, the telltale signs of a reef beginning to die.

Our Cuban colleagues were surprised. This was something new that they hadn't seen just two to three years earlier. We saw no sharks, no groupers and virtually no large, predatory fish, a sure sign of overfishing which contributes to a reef's decline. Although on paper the area is protected—it has the same level of protection as Cuba's better-known Gardens of the Queen—there is virtually no enforcement and the area is fished illegally.

This College Could Become the First 100% Renewable Campus in U.S.

As a growing number of U.S. cities make pledges towards 100 percent renewables, it's easy to forget that the entire state of Hawaii set this important benchmark three years ago when it mandated that all of its electricity must come from renewable sources no later than 2045.

To help the Aloha State meet this ambitious commitment, in 2015, the University of Hawaii (UH) and the Hawaiian Legislature set a collective goal for the university system to be "net-zero" by Jan. 1, 2035, which means the total amount of energy consumed is equal to the amount of renewable energy created.

Silver Nanoparticles in Clothing Wash Out, May Be Toxic

By Sukalyan Sengupta and Tabish Nawaz

Humans have known since ancient times that silver kills or stops the growth of many microorganisms. Hippocrates, the father of medicine, is said to have used silver preparations for treating ulcers and healing wounds. Until the introduction of antibiotics in the 1940s, colloidal silver (tiny particles suspended in a liquid) was a mainstay for treating burns, infected wounds and ulcers. Silver is still used today in wound dressings, in creams and as a coating on medical devices.

Study Finds Timely Emissions Reductions Could Prevent 153 Million Air Pollution Deaths This Century

One of the roadblocks to swift action on climate change is the human brain's tendency to focus on threats and stimuli that are an obvious and noticeable part of their everyday lives, rather than an abstract and future problem, as Amit Dhir explained in The Decision Lab.

Now, a study published in Nature Climate Change Monday shows that acting quickly to curb greenhouse gas emissions would also reduce the air pollution that is already a major urban killer, thereby saving millions of lives within the next 40 years.

Trump Administration Sells Oil and Gas Leases Near Utah National Monuments

The Interior Department on Tuesday is auctioning off 32 parcels of public lands in southeastern Utah for oil and gas development.

The Bureau of Land Management's (BLM) lease sale includes more than 51,000 acres of land near Bears Ears—the national monument significantly scaled back by the Trump administration last year—as well as the Hovenweep and Canyons of the Ancients monuments.

Katharine Hayhoe Reveals Surprising Ways to Talk About Climate Change

By Katie O'Reilly

Katharine Hayhoe isn't your typical atmospheric scientist. Throughout her career, the evangelical Christian and daughter of missionaries has had to convince many (including her pastor husband) that science and religion need not be at odds when it comes to climate change. Hayhoe, who directs Texas Tech's University's Climate Science Center, is CEO of ATMOS Research, a scientific consulting company, and produces the PBS Kids' web series Global Weirding, rose to national prominence in early 2012 after then-presidential candidate Newt Gingrich dropped her chapter from a book he was editing about the environment. The reason? Hayhoe's arguments affirmed that climate change was no liberal hoax. The Toronto native attracted the fury of Rush Limbaugh, who encouraged his listeners to harass her.

Kinder Morgan Pipeline Protest Grows: Arrests Include a Greenpeace Founder, Juno-Nominated Grandfather

By Andy Rowell

Just because you get older, it doesn't mean you cannot stop taking action for what you believe in. And Monday was a case in point. Two seventy-year-olds, still putting their bodies on the line for environmental justice and indigenous rights.

Early Monday morning, the first seventy-year-old, a grandfather of two, and former nominee for Canada's Juno musical award, slipped into Kinder Morgan's compound at one of its sites for the controversial Trans Mountain pipeline and scaled a tree and then erected a mid-air platform with a hammock up in the air.

The Grapes of Trash

By Marlene Cimons

German monk and theologian Martin Luther probably said it best: "Beer is made by men, wine by God." It's true—the world loves its wine. Americans, in fact, downed close to a billion gallons of it in 2016. But winemakers create a lot of waste when they produce all that vino, most of it in seeds, stalks and skins.

Why Mike Pompeo Could Be Even Worse for the Environment Than Rex Tillerson

By Kelle Louaillier

As Secretary of State, Rex Tillerson was one of the most blatant revolving-door cases in the Trump administration and a clear sign that Trump's government was of, by and for the fossil fuel industry. But make no mistake: Mike Pompeo could be far worse.
