Of all the threats to the planet’s ocean, none may be more insidious or have longer-term impact than ocean acidification. It is also the least understood of all the potential harms.
Admittedly it is far easier to visualize plastic afloat on the surface of the Pacific or vast tracts of the Atlantic nearly devoid of fish than a chemical imbalance. But it is the change of acidity that may already be the ocean’s worst enemy.
Try this for a visualization, maybe it will help: 24 million tons of carbon dioxide created by the burning of fossil fuels – or the equivalent of 24 million Volkswagens – are dumped into the world’s ocean every single day.
On top of destroying coral reefs (the equivalent of wiping out rain forests on land) and killing off shellfish beds including mussels and oysters, a new report out of the U.K. suggests that the so-called “evil twin” of global warming is responsible for some fish losing their sense of smell and hearing.

Bora Bora, Society Islands, French Polynesia – I dove last week in the beautiful lagoon that surrounds the tall island to have a first hand look at how the coral reef is doing in this South Pacific resort island. The report is not good.
Descending to 90 feet, it was immediately clear that the reef has been hammered in the past few years. I’ve come here every year for the past decade and have seen incredible change.
I spent most of the morning observing the still-growing reef system just 10 to 30 feet below the surface. Although the waters are warm and magnificently clear, invasive predators and natural disaster have both taken big tolls.
Populations of acanthaster -- also known as the crown-of-thorns starfish – mysteriously arrived in Polynesia in 2006. No one is sure exactly how they got here or where they originated, though invasive species are well known for hitching rides on cargo ships and jumping off far from home. Here in the shallows surrounding Bora Bora – as they have done to reefs on nearby Moorea, Raiatea-Tahaa, Huahine and Maupiti – the predatory starfish have devoured hundreds of acres of coral.

Typically at this time of year a certain breed of shopper purposefully wanders the fish stalls of their favorite grocer taking stock of the piles of fresh oysters carefully arranged on crushed ice or to pick up and judge the heft in their hands of tightly packed tins of caviar, which sell for anywhere from $50 to $2,000.
But maybe this is the year to lay off those two favored treats and replace them with something slightly less traditional: squid.
I know, a big bowl of calamari hardly compares to one of caviar… but, man, there’s a lot of squid out there these days. I’m sure some of those very popular sustainable fish chefs have already dreamed up some special calamari entrée to take advantage of the boom.
