Ocean acidification is often referred to as osteoporosis of the oceans because as acidity rises, shell building creatures such as lobster, oyster, crab, shrimp, and coral are unable to extract the calcium carbonate from the water that they need to build their shells and are thus unable to survive.
My grandfather was Jacques Cousteau, a pioneer of ocean exploration and the co-inventor of scuba diving. Back in the 1940s when he tested out his invention which allowed humans to swim freely in the ocean with a portable air source for the first time in history, very little of the ocean had been explored let alone captured on film.
As our technology evolves, we will have the capacity to reach new, ever-increasing depths. The question is what kind of technology, in the end, do we want to deploy in the far reaches of the ocean? Tools of science, ecology and documentation, or the destructive tools of heavy industry?
I hate plastic bottles. Just think about it before you buy one. We pay more for a gallon of water than we do for a gallon of gas. I think people will realize that water quality standards in most municipalities are as good or better for the stuff coming out of the tap than bottled water companies. You'll save money and save the environment, too.
Don't eat shrimp - it's one of the most unsustainable fish. For every pound that's caught, 10 or 20 pounds of other stuff is killed and dumped back overboard. It's the number one killer of juvenile sea turtles in Mexico. Two good sustainable seafood guides that I'd recommend are from the Monterey Bay Aquarium and the Blue Ocean Institute.
