The Secrets of the Deep
26 March 2018
Swimming, surfing, laying back and listening to the soothing sounds of waves, and the decidedly less soothing sound of seagulls – the seaside can be a wonderful place. Though it’s surface is not all the wondrous ocean has to offer – there’s an entirely different world beneath the waves, and it’s more closely linked to our world of dry land than you (and certain singing crabs) might think.
Seas and oceans cover an amazing two-thirds of our planet’s surface, so it’s no surprise that they’re important. But what might come as a surprise is exactly how the ocean affects our everyday lives. For example, did you know that the ocean plays a critical role in maintaining the quality of the air we breathe? Ocean plants not only produce approximately half of the world’s oxygen, but also help to absorb carbon dioxide and reduce ocean acidity caused by human pollution.
The ocean also provides a lot of our food, directly or indirectly. Seafood in general is known to be a rich source of nutrients such as B-complex vitamins (which can affect energy, metabolism and concentration), vitamin A (which supports vision, the immune system and the reproductive system) and vitamin D (which supports bone health, immune-system efficiency and healthy cell growth). Fish in particular (especially oily fish like salmon, mackerel and sardines) are an excellent source of omega-3 fatty acids, which have a huge range of associated health benefits (from eye health to assisting treat anxiety and depression). But seafood isn’t the end of the story – ocean ingredients such as algae and kelp are vital to produce many other food items, including peanut butter, ice-cream, soy milk and even beer!
The ocean is even linked to your medicine cabinet – many medications contain ocean products. Enzymes and organic chemicals found in coral reefs are used to treat asthma, arthritis and other serious inflammatory conditions, while blue-green algae can be used to treat cancerous conditions.
The ocean truly is a source of inspiration, recreation and enjoyment for the many millions of people who interact with it. If your thirst for underwater knowledge still isn’t satisfied, or if you have a curious young mind at home who’s ready to dive right in, you can learn more about the world beneath the waves in Hinkler’s Know and Glow: Ocean Sticker Activities!
For instance, did you know that
- The world’s highest mountain, measured from its underwater base to its peak, is Mauna Kauna, Hawaii, at 33,480 feet (10,205 m): that’s taller than Mount Everest!
- The blue whale weighs more than the largest dinosaur that lived on Earth—up to 180 tonnes (200 tons). Its tongue alone weighs an amazing 3 tons (2.7 tonnes)!
- Scientists have discovered that each dolphin has its own special whistle to identify itself, just like a name!
- The Vikings reached Newfoundland in North America 500 years before Christopher Columbus crossed the Atlantic.
