A recent study found that 90 percent of seabirds have eaten plastic, and a lot of that plastic comes from the rings that hold together six-packs of beer, soda and other beverages. The marine life that lives in the oceans ingest plastics, too. These toxic plastics harm the health of our sea life, often killing them.

Saltwater Brewery in Florida created a six-pack ring that feeds animals instead of killing them. Many six-pack rings from beer end up in the ocean, so the brewery took barley and wheat remnants from the brewing process and turned them into an edible, compostable, biodegradable product that holds together a six-pack but doesn't harm birds or sea life if it ends up in the ocean. It's also strong enough to handle the weight of a six-pack.

This is the first time a 100 percent edible and biodegradable packaging has been implemented in the beer industry. The manufacturing cost of the edible six-pack ring raises the price of the beer, but the narrator of the video points out that if most breweries implemented this safe and sustainable product, the cost would be competitive with the plastic six-pack rings. Hundreds of thousands of lives could be saved.

Why has no one thought of this before? In addition to being impressed by this product, I'm wondering how quickly I can put together a business plan, get funding and partner with Saltwater Brewery to open up a plant that can produce edible six-pack rings for all breweries.

I bet there's money to be made from this smart, responsible idea.

Sharks never cease to captivate our imaginations. Strange, scary, beautiful, powerful, unique, special ... the long list of descriptors would dwarf a whale shark! Sharks have had hundreds of millions of years to evolve and dominate the sea as perfectly honed predators. The more we study them, the more surprises they reveal. Here are just a few fascinating facts about sharks around the world.

An emergency ascent is the response of last resort to an adverse event or perceived threat during a dive. Divers are trained in standard emergency ascent procedures that, when performed successfully, mitigate the dangers. However, few people practice these skills, and when called to perform them in a crisis, a diver may be at risk for serious injury or even death.

Our small wooden vessel rocked gently on the water, revealing little of the wild currents sweeping over the coral reefs below. On the signal of our experienced dive guide Arun, we rolled off the boat and descended into the cobalt ocean.

Vertigo is the feeling that the world around you is moving, spinning or tilting while you are remaining essentially still. Vertigo can be a result of a number of ailments, ranging from an infection in the inner ear to chronic problems such as Meniere’s disease.

Vertigo is not uncommon among divers, and your experience with it occurring when you are at significant depth is fairly typical. Diving physics tells us that the greatest pressure changes occur closer to the surface, but as the diver descends, equalizing the pressure in the middle ear is still very important. Divers generally continue to descend even when having difculty with equalizing. Plus, the middle ears need to equalize during ascent as well.

You are experiencing alternobaric vertigo, which is caused by unequal pressures between your middle-ear compartments. The pressure diference does not have to be very great. The inequality is communicated to the inner ear organs, resulting in vertigo. Divers can also experience nausea and vomiting. Vertigo is usually more common while a diver ascends. Not only are the symptoms uncomfortable, but they also can lead to catastrophic problems for the diver. Vertigo can also occur when diving with a hood if one side of the hood seals over the ear tighter than the other.

Prevention of vertigo during diving requires careful, gradual and continuous equalization of the pressures within the middle ear throughout the dive.
