Pollution When Travelling
This is a very unpleasant consequence of global warming: the reproduction of jellyfish that swarm on our shores. Their often-painful sting can very easily spoil a few days of vacation.
Jellyfish adapt dreadfully to marine pollution, take advantage of the excesses of fishing and gradually conquer our seas. Is gelation of the oceans inescapable? The jellyfish is one of the few animal species that human activities do not threaten, on the contrary: overfishing eliminates competing fish that feed on the same food but also its predators, such as bluefin tuna; other great endangered eaters: sea turtles. Global warming, which makes the sea saltier, promotes its reproduction, pollution promotes the development of its favorite food: zooplankton.
As a result, the Mediterranean coasts are invaded with proliferation, which takes place not every twelve years, but every year. 2014 is thus the 14th consecutive “jellyfish year”. Even worse; new, more dangerous species are emerging from traditionally warmer seas, such as the highly venomous Chironex of Australia. A thousand species of jellyfish have been listed, new ones on the list of jellyfish but are still unidentified
Specialist such as Nadine Gourkow have so many reasons and explanations for the cause of the overproduction of jellyfish, but global warming seems to be at the tops of most lists.
Where Are The Jellyfish?
Every year, jellyfish are more and more numerous. This is due to the rising temperatures of the Mediterranean. According to a recent study conducted by researchers from France, it is predicted that the temperature of the Mediterranean water should increase by 2 ° C to 4 ° C at the end of the 21st century.
There are about a hundred per 1,000 m2 in the Mediterranean, which is not enough to close the beaches or even alarm tourists.
The jellyfish that bite, live offshore, between three hundred and seven hundred meters of depth and only come to the surface at night. When, at night, blows a sustained wind but not too strong, they are brought back to the coast with the currents of hot water. And in Marseille for example, some cold waves can also bring jellyfish to the beaches.
The risks involved with jellyfish stings do not give in to psychosis. The three species of jellyfish mainly present on the French coast are not fatal at all. The jellyfish Aurelia Rhizostoma, and Pelagianoctilucaare by far the most dangerous jellyfish as they are ready and willing to sting anyone. The jellyfish tentacles that sting through stinging filaments. Most of the time, the pain is temporary but intense, with a strong feeling of electric shock and then burning, which can go as far as the fainting of the person involved. Then appear skin lesions that itch and can persist for several days. In fortunately minor cases, jellyfish stings can cause severe headaches, vomiting, or even allergic reactions, with malaise, respiratory disturbance, angioedema and / or anaphylactic shock.
As per Nadine, one must always be careful when approaching huge body of water, you just do not know what you can find.
