“Coral reefs are a casualty of climate change” — reflections from Chasing Coral

“If we can’t save this ecosystem, are we gonna have the courage to save the next one down the line?”

Imagine going to your favorite place in the world, only to find it was completely devastated.

That’s what producers, divers, and everyone involved in Chasing Coral found.

The film Chasing Coral follows the same structure as its predecessor Chasing Ice: a documentary produced to highlight something we’re going to lose (or have already lost) because of climate change.

After watching Chasing Ice, I felt hope. But after watching Chasing Coral, I feel despair.

In 2012, Chasing Ice made me feel urgency — I knew climate change was real, and this film was made (in my eyes) to show people the effects of this global issue. I felt equipped (with tons of icy ammo) to shout about climate change from the rooftops!

But now, in 2017, Chasing Coral almost made me cry. Because humans have dumped carbon into the atmosphere for so long, and have delayed on climate action, we’re finally losing something we cannot replace — the world’s coral. And the documentary film crew spent months documenting the damage.

Coral bleaching all starts with the rise in global temperatures, and where that heat is stored. The ocean takes up 93 percent of the world’s heat, and without it, we’d already be fried on land.

Bleaching is a side effect of the ocean’s heat. When the ocean is too hot, corals get stressed out, and the algae living on the coral depart (or are ejected), causing the symbiotic relationship between algae and coral tissue to waste. When the algae is gone, coral loses their source of food, and bleaches. Not all bleached coral is dead, but once coral is bleached, it’s less likely for the coral to return to a healthy state.

This isn’t a “natural” cycle, either. Coral bleaching has been directly attributed to climate change.

The impacts continue on. This week, scientists announced the second coral bleaching event in a row in the Great Barrier Reef. Corals around the globe have been subject to bleaching in recent decades, too, not just in Australia. More heat continues to pile up in the ocean, even turning the Arctic into the Atlantic.

“The ocean controls everything. Without a healthy ocean, we do not have a healthy planet.”

Scientists in the film are concerned that continual bleaching events will wreck coral and their habitats for good — if they always bleach, they will never have enough food, and will just die off. This would lead to an ecosystem collapse, where entire classes of organisms could go extinct.

Ocean scientists are sounding the alarm. And what’s their solution? Stop using fossil fuels now.

Is losing the Great Barrier Reef going to wake up the world?

Water pollution may make #Rio2016 the most hazardous yet

Olympic visitors flocking to Rio de Janiero, Brazil for this year’s Olympic games have been warned: “Don’t put your head underwater.”

According to a study contracted by the Associated Press, the waters along the coast of Rio are filled with a toxic sludge of raw sewage, “teeming with dangerous viruses and bacteria.” In an amazingly horrible comparison, swimmers need to ingest only three teaspoons of water to be almost certain of contracting a virus, with levels of pollutants “1.7m times what would be considered alarming in the United States and Europe.”

But it’s not just a warning for the visitors — Olympians competing in the bay (sailors, rowers, and open-water swimmers) have had to take extra precautions in the form of antibiotics and anti-pollution microbial suits.

“[The water quality] is a real concern. We’re going to have to be very disciplined about how we’re taking care of ourselves,” said Meghan O’Leary, a member of the U.S. rowing team. “Don’t touch our face if we touch the water. Covering our water bottles with plastic bags. We get splashed a lot. I sit in bow. It’s going to happen. We’re just going to try to control everything we can.”

Unfortunately, the most polluted areas are the points where Olympic rowing and sailing races will take place.

The New York Times writes that a part of Rio’s Olympic bid was to “capture and treat 80 percent of the sewage that flows into Guanabara Bay,” which certainly isn’t happening by the time the Olympics start on Friday.

In the long term, Rio will be added to the list of Olympic host cities with issues — including the lack of snow in Sochi in 2014 and in the upcoming winter games in Beijing in 2022.

Why every day should be World Water Day

Water is life.

Quite simply, we wouldn’t survive without it. More broadly, we use it for energy (directly and indirectly through fracking and natural gas production), farming, and personal hygiene/bathing. Aside from this, there are tons of other ways we use water that we don’t think about — especially in the manufacturing process of goods and clothing.

A quick refresher: 97.5 percent of Earth’s water is salt water, which means 2.5% is left as freshwater. Nearly 70 percent of that freshwater is frozen Antarctica and Greenland. The rest of THAT is trapped in deep underground aquifers.

So that leaves about 1 percent of the world’s fresh water accessible for human. 1 PERCENT. And what we do with it makes all the difference. That’s where World Water Day comes in.

World Water Day (March 22nd every year) is a United Nations holiday that was born to bring public awareness to global water problems and solutions.

This year, the UN is focused on water and jobs — namely the intersection of the two.

Today, almost half of the world’s workers – 1.5 billion people – work in water related sectors and nearly all jobs depend on water and those that ensure its safe delivery. Yet the millions of people who work in water are often not recognized or protected by basic labour rights. The theme in 2016 — water and jobs — is focusing on how enough quantity and quality of water can change workers’ lives and livelihoods – and even transform societies and economies.

In past years, World Water Day has been focused on sustainable development, water and energy, and international water cooperation.

And all of these topics relate back to the most important of them all — conservation. With different energy sources taking over, like natural gas, water use has declined in the U.S. at a time where it’s so necessary to conserve (considering high drought levels in the Western U.S.).

What’s at Stake for the World: Infographics

In case you haven’t heard, negotiators in Paris at COP21 have made a historic climate deal that hopes to limit global warming below 2°C.

Why 2°C? You may have heard the world is warming, and that warming has been attributed to manmade emissions. The United Nations has adopted 2°C as the highest threshold for warming with human-caused carbon emissions in order to drive nations to make a climate agreement (like the one in Paris) that would limit the most disastrous effects of climate change.

And thanks to InsideClimate News, we can see what’s at stake in infographic form!

Deforestation is a huge problem globally because forests suck up carbon that could end up in the atmosphere.

Sea levels are rising, which is bad news for everyone in a coastal city (especially in China).

And no, I haven’t forgotten about wildlife! They’re at risk, too.
