I’ve all the time marveled at this ocean planet. 71 p.c of the Earth’s floor is roofed by water and 96.5 p.c of it’s contained within the oceans. Really, it’s actually one ocean with bits of land popping up right here and there.
How is it we’re so fortunate to have a planet with an ocean that’s able to sustaining such an abundance of life types on land and sea? The place did the water come from? Scientists have theories however nothing is definite. Do different planets have water? Proof factors to oceans on different planets, however Earth is the one identified planet to have constant, steady our bodies of liquid water on its floor. That’s as a result of Earth is within the liveable zone, that means that it isn’t too near the solar for the warmth to evaporate water and never too far to freeze it. After which there’s the right quantity of gravity which holds the water the place we wish it to be.
I do know that exploring area is as thrilling because it will get, however we all know so little about this miracle planet that we reside on, that I ponder why we aren’t extra inquisitive about it. A NASA worker as soon as informed me that the amount of cash that goes into exploring the supply and upkeep of life on Earth, the oceans, is a rounding-error within the amount of cash spent on area exploration. It boggles my thoughts! Is there something on the market that’s extra lovely than the place we already reside?
The Significance of Coral Reefs
I believe we have to shield and nurture Planet Earth, and the one approach we will do that’s to attempt to perceive it. One factor we do know is that the oceans are beneath stress. Local weather change is actually altering all the pieces. Take, for instance, our barrier reefs. Australia’s Nice Barrier Reef is so big that it may be seen from area. It stretches over 1,400 miles. It’s house to billions of marine species and is the world’s largest residing organism. It’s significance to our survival can’t be over-estimate, all reefs are necessary to our survival. Why?
Nicely, selfishly from a human viewpoint, they shield our shorelines from the ravages of storms which are changing into increasingly frequent because of the excessive fluctuations of ocean temperatures. Storms erode coastlines taking houses and livelihoods with them. Over half a billion folks rely on reefs for meals, earnings, and safety. The web financial worth of the world’s coral reefs is estimated to be tens of billions of {dollars} per yr.
And what of the reefs themselves which are typically known as “the rainforests of the ocean?” About 25% of the ocean’s fish rely on wholesome coral reefs. That’s a number of fish! They discover shelter and meals, reproduce, and rear their younger within the nooks and crannies shaped by corals. (And right here I’ve to digress and suggest a documentary known as “My Octopus Instructor.” Should you haven’t seen it, put it on the prime of your record. It received’t disappoint.).
Reefs are basic to a wholesome ocean. However coral reef ecosystems are severely threatened. Air pollution, sedimentation from run-off, unsustainable fishing practices, and local weather change are resulting in coral bleaching and loss of life. In 2005, the U.S. misplaced half of its coral reefs within the Caribbean in a single yr due to an enormous bleaching occasion. Between 2014 and 2017 unusually heat waters affected 70% of coral reefs. The Nice Barrier Reef misplaced lots of of miles to bleaching.

Utilizing Reef Secure Sunscreen
There may be extra however I’m going to finish with a plea about sunscreens and carrying one that’s thought-about reef-safe. A number of widespread sunscreen elements have been proven to be poisonous to coral reefs. Once more, whether or not you’re within the ocean or not, what you put on will finally wash off and find yourself there. Thousands and thousands of individuals put on sunscreens and don’t know that they’re negatively impacting coral reefs.

Key elements to keep away from are Oxybenzone and Octinoxate. Moreover, look out for Benzophenone-1, Benzophenone-8, OD-PABA, 4-Methylbenzylidene camphor, 3-Benzylidene camphor, and Octocrylene. These can have an effect on corals’ reproductive cycle, injury DNA, and worsen the consequences of coral bleaching. Lively sunscreen elements which are thought-about reef-safe are Zinc Oxide and Titanium Dioxide.
A fast phrase concerning the quantity of safety from SPF rankings. (By the way in which, SPF solely refers to UVB safety). An SPF 15 protects from 93% of UVB rays. SPF 30 protects from 97%.
