The abilities of Dolphins

The abilities of Dolphins

            Among all the creatures that live in the ocean; an unexpected mammal has the same intelligence as human beings have, dolphins.  It was found that dolphins have the ability to be alert, they have their own unique personalities and that their capacity for intelligence is very high.  One case will be Ciere, a dolphin that a scientis was working with.  The scientis would reward her if she did what the scientis wanted her to do something, if the dolphin did not do then, the scientist would do what is called “time-out”.  This meant that the scientists would turn her back and walk away, the dolphin reward for doing what it was command of her was to get a fish but without the tail.  The dolphin Ciere did not like the fish with the tail, one day the scientist forgot to cut the tail and Ciere spit it out, Ciere the dolphin turn around give her back to the scientist and walk away.  This means that dolphin can copy what we humans do, the scientist was using time out as a correction for the dolphin and the dolphin end up using it on the scientist. This experiment shows that dolphins do understand what human beings are asking of them and that they also can feel disappointment when not getting what they want, because of their high intelligence they show us humans that dolphin can be displeased too.  Also, in the moment of capturing dolphins from the wild does not mean that they would cooperative, in some cases the dolphin would not survive, because of the impact that the dolphin are not use to being trap.   Furthermore it is concluded that because of their high intelligence dolphins can be traumatize if taken from captivity and use them for entertainment or to show them off for profit.  Because of their big brains and intelligence the dolphin was classified as the second smartest creature on earth.
            In the movie the “Cove” is show how bottlenose dolphins are being brutally murder, killing them slowly and hunted down to be sale for profit.  All this take place in Taiji Japan, a lot of dolphins are being murder to be eaten and eating dolphin Is not good for human beings because dolphins are poison. Dolphin contains a dangerously high levels of mercury on their body.  This is because we humans burn mercury going to the ocean, from their little marine creatures drink it and from their big marine creatures eat this animals and end up passing the mercury to does big predators.  Human beings are the top predators in the food chain, this means individuals go out and hunt for animals, animals don’t stand a chance to escape our advance hunting tools.  This applies to the dolphin, they don’t stand a chance even if individuals don’t tried to capture them and on top of all they are not meant to be eaten by humans.  Humans by eating such an intelligent mammal they are eating mercury which can cause brain damage for us, also it can cause for problems for human babies, they can be born with some kind of disease that can be incurable for them.  Also dolphin might be extinct if not stop the unnecessary massacre, in a town name Ikki in Japan they use to be a lot of dolphin but with the amount of excessively killing, there is not a single dolphin in that town any more and that can happen in Taiji and other parts of the world.

OVERFISHING


 One of the things that we individuals don’t often think when it comes to fishing, is that fishing can have a big impact in our oceans.  Overfishing is an issue that is affecting the ocean especially in the Mediterranean, most of the species living in the Mediterranean are being wipeout do to overfishing.  It is predicted by the scientists that in a few years more than 40 species could be extinct In the Mediterranean.  The cause of all these is the method that the fisher man use to catch the fish, fishing lines, gill and specially trawling net are the cause of an  unnecessary caught of fish.  Some of this fish that are being caught and they don’t event have a commercial value do to their size or is not the species of fish that fisherman intended to catch.  Also trawling nets destroyed the sea bottom when fish are being caught in the process, it is devastating because small marine creatures live their that are part of the food chain for other marine creatures.  On top of that the sea floor is a home for marine creatures and there is the place that they reproduce.  Scientists recommend that fishing law need to be reinforce, make new marine reserve, review the fishing quotas and minimize as much that we can the pollution on the ocean.
            If the  overfishing continues with out putting limitations, then their will not be no more species in the ocean to exit and be part of the ecosystem.  It is important that we live the marine species to reproduce so they can have time reproduce and spread as they were ones before fisherman started to overfish.  Everyday that pass by it is more difficult for people to find these marine creatures in the ocean.  The bony fish, bluefin tuna, sea bass, and sharks are some of the few species that are in danger to vanish from our ecosystem.   What is going to happened when this marine creatures are no more.  Some of these marine creatures have a purposed in the ocean, it can help other marine creature and in the long run it might benefit human beings in a way.  The fishing industries are having difficulties on finding some of these marine specimens, because of this fisherman are catching few fish and it being sale at a high prize and in some parts of the world fish is very popular, like Japan, its population consume 80 percent of bluefin fish and two different species of tuna are used specially for does that are  sushi lovers.  It is of big concern that that our leaders start taking some action about this situation,  the marine ecosystem is being affected because we human beings are doing to much overfishing or unnecessary and we are doing more, pollution and trash.  People are the cause why  Mother Nature is being affected by some thins that people do.  If some kind of action is not taken soon than there will be nothing remain that can sustain our ecosystem.
