The 7 Biggest Threats to Our Oceans: Threat #7: Ocean Acidification

Posted by PuraKai Clothing on Oct 26, 2015 2:17:00 PM

Did you know that our oceans not only act as a filter for the underwater environment, but that they also serve as a filter for the air we breathe here on land? In fact, our oceans absorb almost 30 percent of the carbon dioxide within the Earth’s atmosphere.

The 7 Biggest Threats to Our Ocean: Threat #6 The Garbage Patch

Posted by PuraKai Clothing on Sep 22, 2015 2:14:00 PM

AKA “The Great Pacific Garbage Patch”. Great, as in big, not as in good. As the global population expands, so does the amount of trash we produce. Ever wonder where is all goes? A large portion of that trash unfortunately ends up in our ocean. While it may seem like an out of sight, out of mind scenario, quite the opposite is true. Once the trash meets the sea, it is swept up in the oceans currents, where it is then carried to distant areas as the currents diverge and come together. These collections of trash have become known as the trash islands.

One of the biggest, and more famous of these trash islands (yeah, there is more than just one, and this one is comparable to the size twice that of Texas) is located between Hawaii and the California coast in a location known as the North Pacific Subtropical Gyre.  A gyre is a geographical term for a large system of rotating ocean currents, usually influenced by wind movements. They are caused by the Earth’s Coriolis Effect, and are often referred to as a swirling vortex within the sea, kind of like when you pull the drain in the bath tub and that funnel appears as all the water is sucked down the drain.

The 7 Biggest Threats to Our Oceans: Threat #5 Mercury Pollution in our Oceans

Posted by PuraKai Clothing on Aug 18, 2015 2:11:00 PM

Look at any seafood guide and you're bound to come across the occasional red flag with an ominous warning: “High in Mercury.” Scary enough, but what exactly does that mean? Just how is mercury winding up in the fish on your plate?

Mercury, a naturally occurring, yet toxic element when exposed in large quantities, is polluting our Earth’s oceans. Within recent years, the amount of mercury on the surface of the ocean, has more than tripled, taking a toll on the environment and the animals within it. Sadly the U.S alone, generates nearly half of all mercury emissions, averaging around 33 tons annually from power plants alone.

The 7 Biggest Threats to Our Oceans: Threat #4 Dead Zones

Posted by PuraKai Clothing on Jul 12, 2015 2:09:00 PM

What is a “dead zone”? The term dead zone is a common name given to an area in the ocean that is hypoxic, meaning it is an area with such low oxygen concentration that animal life cannot survive or thrive within it. The result, areas of the ocean that were once abundant with life, become biological, barren deserts.

While dead zones can occur naturally in any body of water, a major cause is from excessive nutrient pollution from humans, coupled with other factors, such as algae blooms, that deplete the oxygen required to support marine life with in the water.

The 7 Biggest Threats to Our Oceans: Threat #3 Dying Coral Reefs

Posted by PuraKai Clothing on Jun 8, 2015 2:02:00 PM

Coral reefs are to our oceans as tropical rainforests are to our lands. These vast, uniquely diverse, interdependent ecosystems, are home to millions of marine species, many yet to be discovered. Ocean inhabitants and humans depend on the many resources these reefs provide in order to thrive. Unfortunately, there are several factors endangering the health and vitality of these delicate marine habitats. Recent reports say that 90% of coral reefs worldwide will be threatened with extinction by the year 2030. Until recent years, the surf industry has been silent in the world of coral reef conservation. However, with a little motivation and education, ocean lovers of all genres are becoming aware of the threats, and learning what they can do to save our disappearing reefs before it’s too late.

“Think of it like the Serengeti, with lions and the antelopes they feed on. When all the lions are gone, there will be antelopes everywhere. Our oceans are losing their lions and pretty soon will have nothing but antelopes.”
