Beyond the world we all live,there are another one,more surprising,odd and intriguing than ours-underwater life.This place is surrounded by an halo of strangeness,mistery and magic.Even though about 71 percent of the Earth’s surface is covered by water ,and of the whole water 96.5 percent are represented by oceans,we have only explored less than 5  percent  of our planet’s  oceans.

They represent the mistery and the magic in their pure form.Relating to the treasures the  humanity lost in the oceans over time,the deep sea is the largest museum on Earth:It is estimated there are more artifacts in the ocean than in all of the world’s museums.But the truly treasure of the ocean are not these human-made things,but the gifts of the nature.

 

About 94% of life on Earth is aquatic.In fact,the creatures who live on land come from  aquatic species that have evolved continuously over the millennia. Consequently,we are a minority and our existence is due to ocean.And how reward we this environment?

This jewel is not  just beautiful.The ocean is vital for humans’ survival.The Fish in the ocean would be a great source of food for poor people who’s starving.It requires no arable land,produce little carbon dioxide and the costs are lower than chicken,pork or lamb. It will be an accessible source to poverty  and for those deal with combating starvation.

Unfortunately,is still a big problem:if we do not sustainably use the marine resourses,we’ll end with a large area of water without life in it-an environment without species.In the last years,irresponsible fishing has reduced 90% of many wild fish populations,especially big fish.This is a historically low level,right now,at the moment when the world needs the oceans more than ever.

According to the United Nations Food and Agriculture Organization’At this moment there are 7 billions people on Earth,and this figure will grow to a 9 billion people by 2050.Right now,795 million people on this planet suffer from hunger,and we do not have enough arable land and fresh water to feed 2 billion more without incurring severe looses to the natural world.’

 The truth is at this time we waste oceans’ assets,and we do that in a too fast way to allow them to recover.We cut sharks’ fins and kill them for a banal soup,we hurl poison and explosives to kill or stun fish,even in coral reefs-in western Pacific countries;we throw big nets which catch not just the wished fish,but  many species who are caught in accidentaly and throw back in the water ,dead,in many times.These bycatches,according to statistics, can reach up to 80% or even 90% of the total catch.And that’s because only a unsustainable management of fishing,allowing the use of the destructive nets for the ecosystems. Fishing really need to be controlled by authorities,that if  we want to protect the sea and its resources.

 We do not only damage the ocean directly,but indirectly,through the pollution we do,we kill a lot of marine animals.And the biggest  problem is the  plastic.Plastic kill up to 100,000 sea mammals and  other animals each year.The marine birds confuse the plastic with the fish and they die suffocated,the sea turtles do the same, confounding it with the jellyfish.The plastic is a very durable material which don’t biodegrade.However,in contact with sunlight,it break down into smaller and smaller pieces-some of them are little enough to be compared with plankton-,thing that make it hard to be cleared.But,even so,there  are ways water can be filtered.

Yes,I often repeat,but only a sustainable employment of resourses could save the ocean from environmental ruin.I think we all heard about global warming/climate change and its consequences. But know we what effect it has on the ocean?Let`s talk about a “sensitive” topic.Corals.Coral Reefs comprise only 0.5% of the ocean floor,but more than 90% of our marine animals depend on them.In the recent years,we’ve lost up to 50% of the world’s corals.Pollution,tourism,fishing pose hazards to the Reef’s fragile ecosystem,but climate change is its most serious threat.Coral bleaching  has completely changed The Great Barrier of Reefs in Australia.It’s happening so fast,that we cannot grow corals fast enough to replace them. Until now,the temperature of the oceans has increased with two degrees Celsius and that destroyed a half of the corals from the whole world.By 2050,it’s expected to rise at 4 degrees.If we let the temperature to grow until this level,we’ll live in a world without corals.

The climate change will not stop when the corals’ll die…Since the start of the Industrial Revolution,the ocean has absorbed about 30% of the carbon dioxide humans have sent into the atmosphere.This great service have come with a big cost-ocean acidification.This  acidification afects a lot marine creatures with  shells,which form their skeletons using calcium carbonate,and,of course,the corals,whose formation  depends on this substance.

Even if we live near the ocean,even if not,we are all connected to it.Ocean generates 50% oxygen for breathing!According to the  scientists,there’s oxygen from ocean in every breathe we take-most of this oxygen comes from phytoplankton(microscopical ocean plants).,and the rest from seaweed.But the plankton is affected by global warming,too.

  • So,dear people,please,let’s struggle with pollution,reducing energy consumpmation, using fewer plastic products ,taking care of the corals and fish and support organizations  who work to protect the ocean.

“No water,no life,

No blue,no green”-Sylvya Earle

 

Yeah, we destroyed much of our oceans’ecosystems,but there are still good news…50% of the corals are healthy,10% of the big fish still live-we have enough time to change the appearances.Remember,only a sustainable  employment can save the environments,and that not just in the ocean-in the entire world’s natural ecosystems.
