Recommended: Effects on the Earth from climate change
Earth's climate is changing, it is possible at an unprecedented rate. Overall, the earth is warming, sea ice and glaciers retreat, sea level rise, as well as pollutants accumulate in the environment and in vivo. These clear physical change will undoubtedly affect marine ecosystems. This research is talking about the important of dolphin in the ecosystem, causes of dolphin being threatened to extinction and the discussion about the way to protect dolphin.
Keywords: climate change, marine ecosystems, marine mammals, dolphin, extinction of species and protection.
Introduction
In human mindset, the dolphin is a mammal animals that living in the sea, or sometimes can watch a dolphin show at the zoo. In fact, most people do not know that dolphins have slowly face the extinction problem (William, 1996). Many fishermen were catches dolphin secretly and a lots people was eaten dolphin meat without knowing. There are many different species of dolphin for example River dolphin, Black dolphin, True dolphin and Bottlenose dolphin (Nathan, 1997). DNA code is a way to separate and identify the

Since they are the top predators in the ocean food chain, several species of fish and squid they consume concentrated in their bodies can be used in contaminants in water (Kester, 2008). They infectious diseases among fish populations and ensure the reproduction of fisheries resources. It has been proven in many studies, the elimination of top predators in marine ecosystems have an adverse impact on the entire ecosystem of the cascade (Crispin, 2008). By killing dolphins, we kill the oceans, which could lead to more disease and reduce fish populations’ health police. To kill dolphins, therefore, it means direct damage to sustainable fisheries. Therefore, monitoring and dolphins content of pollutants in their bodies will help scientists to protect the environment (Kester,
One of the most common dolphins that are found in southern California is the bottlenose dolphin (Kelly). The bottlenose dolphin is mainly found in coastal waters between 45 degrees north and 45 degrees south, also in Northern Europe waters. It is believed that there are two types of bottlenose dolphin regional wise: oceanic form and coastal form. This species is studied the most by biologists (Jefferson). The coastal population lives in fairly open groups with twenty or less in a pod, some groups are found to contain more in open ocean. It is not uncommon for these species to interact and breed with other species, as would a human interact with other diverse humans. The dolphins feeding behavior is adapted to the availability of resources. They sometimes are known to work together to catch fish from large schools, they also trail behind large fishing boats to catch what falls behind (Leatherwood).
The proposal of eliminating dolphin hunting serves to achieve important concepts that people should have. The biggest drawback of dolphin hunting is the massacre. Slaughtering dolphins are blatantly immoral, especially in the brutal way Taiji hunters did. Unlike livestock, dolphins are not artificially bred and raised. They are born and beloved by their parents and also their pods. In addition, they are free-living animals that are not meant to be killed by humans. People have no rights to ruin their lives because people didn’t benefit them anyways. Furthermore, dolphins, unlike fish, have feelings, meaning that they can feel the pain when they are butchered and when they see their loved ones slain (Carpenter).
Lastly, with dealing with groups there are many task group techniques and concepts that are associated. For example, there are four active listening techniques that are effective for macro practice. The research states that the four techniques are charting, balloons, dolphins, and parking lot. As previously stated, my group used the balloon analogy when brainstorming for many tasks. We also used the Dolphin analogy. The Dolphin analogy is defined as acknowledging and validating every idea and then move on. It is referred to dolphin or whale watching where you will identify the mammal (acknowledge), take pictures (validate), and then move one. This analogy was conveyed in the third task where we had to create a song. While brainstorming a song,

The Bottle-nosed Dolphin is the most studied and generally the best-known species of dolphin. Bottle-nosed dolphins are classified "Tursiops truncates" in scientific name, and belong to the family Delphinidae, in the suborder Odontoceti, order Cetacea.
Will there ever be a limit as to how many and which type of animals can be killed for consumption by humans? Many will be surprised at the variety of exotic foods that exist around the world such as giraffe, camel, worms, scorpions, and other insects. Dolphin and whale meat is widely enjoyed in Japan especially in the small town of Taiji, Japan where a big secret has been kept for a very long time. There are many changes that can be and need to be made in this big world of ours, but it is not just our world. We share the earth with many great creatures and animals, including dolphins. That is why one of the most important changes that needs to be made in this world is the cease of brutally massacring of dolphins and consumption
Imagine, homes destroyed, a town with no electricity, and nothing but destruction left. This was the scene for many people after hurricane Sandy touched down and swept through their city. A local high school football team, the Beach Channel Dolphins were set to go to the playoffs . Their team was scattered, some arriving late to the game and their team only had two practices prior to the big game. If anyone had an excuse to not play, it was the Dolphins, but they weren't going to let a hurricane stop them from playing. Although they lost, they proved that no matter what someone faces, he/she can persevere(Source B). The Dolphins aren’t the only ones who have faced, or are going to face adversity. We all, at some point or another, will most

Each year,millions of people across the world travel to marine parks, for the chance to see one of the most intelligent, fascinating beings of this Earth, the marine mammal. However, this aquarium is actually a torturous jail cell for the marine mammals that inhabit it. Research has shown that these animals were never fit for captivity. In fact, according to the popular documentary “Blackfish”, more than seventy trainers have been injured by the captive marine mammal, though not a single aggressive tendency toward humans has ever been documented to have occurred in the ocean. It is a likely assumption, that the conditions of marine parks are a cause for aggressive and depressive behaviors in these animals. These intelligent, highly evolved,
Animal extinction is an issue that is occurring all over the globe. It is also something that has occurred since the beginning of time. However, it used to be natural process that would take a long time, now with human involvement the extinction of certain species is accelerating. Most species become extinct because of habitat destruction, introduction of non-native organisms, and direct killing. The marine species are no exception to the human acceleration in extinction either by the general benefit received by them, but only those classified as more valuable that other species get a voice to classify them as endangered while the other are extinct.
Oceans are such so vast that people underestimate the impact their actions —seeming so insignificant— have on them. Humans have by and large taken the oceans for granted; not considering how important a healthy ocean is to our survival. A popular mind-set is that the oceans are a bottomless supply of fish, natural resources, and an infinite waste dump. There are myriad reasons why the oceans should be saved and the most obvious one is marine life. With 71% of the Earth being covered by water, it is obvious that sea creatures are predominant form of life, making up 80% of the species of life on Earth. However, as important as marine life is, that is not the only reason why saving the oceans is crucial. The ocean floor provides natural resources such as, oil, natural gas, petroleum, minerals, medications, and ingredients for foods and products. The economic benefits of the oceans are huge and significant, as well. Fishing and fish products have provided employment to 38 million people and have generated about $124 billion in economic benefits. However, oceans are on the verge of crisis, marine life, natural resources, transportation, the economy, and important ingredients are at risk due to overfishing, pollution, and acidification. Thus, in this essay I will argue that, oceans are not impervious to human activity and threatening the health of the ocean threatens the health of humanity, since oceans key to our survival.
Research from the University of California San Diego Scripps Institution of Oceanography said that species in the ocean consume a projected 12,000 to 24,000 tons of plastic every year in the Pacific Ocean (Nall, 2014). Pollution of recyclable materials in the oceans is one of the leading causes of why some marine species are nearing extinction. Many authors of articles and books analyzing this topic tend to agree that pollution of our oceans is a problem. The future of this problem is where their ideas tend to differ. The following four literature reviews attempt to demonstrate and support my belief that pollution is getting worse in the ocean and more marine life ecosystems are being affected, but there are things that we as humans can do to change this. Imagine a world where we didn’t have to constantly worry about the vicious cycle of humans affecting animals and then animals in turn affecting us through consumption.
There are many reasons why dolphins are very intelligent animals, there are 33 different types of marine dolphins, 4 types of river dolphins, and 6 types of porpoises (dolphins are mammals). Some of the dolphinspeople may think they would be whales, because of their looks, but they are dolphins. Dolphins have a strong behavior; they are very social and travel in groups together. They commonly swim in groups of 2-15 . Severalof different groups of dolphins may temporarily join, for several minutes or hours. In the open waters of theocean, some dolphins will leave their group and change associates and adapt with different dolphins threw outtime (Dolphins communication). In the groups, some members will form a strong bond with one another in thepod. The sizes of the groups tend to increase with the water depth of the ocean and the openness of the habitat, this usually happens when protection with strong with each other and foraging st...
Did you know that more than 90 percent of all organisms that have ever lived on Earth are extinct? According to Pandey, the author of Humans Pushing Marine Life toward ‘Major Extinction’, nearly 10,000 species go extinct each year, and this rate is estimated to be 1,000 times higher than the natural extinction rate (1). Human beings are causing irreversible damage to the oceans and their wildlife, which is being led by two major reasons: Commercial fishing or over-fishing, which damaged the marine environment and caused a loss in the marine life diversity, and pollution, which is a primary way of the extinction causes that drastically modifies the marine life habitat. As a result of the commercial fishing and pollution, many of the marine species will start disappearing of the oceans. Briggs emphasizes that over-fishing “has induced population collapses in many species. So instead of having less than a hundred species at risk, as was the case some 30-40 years ago, there are now a thousand or more (10).”
Did you know in the world there are more than 90 species of whales, dolphins, and porpoises? (WDC) The dolphin is a very important animal to the ocean and there are many different types to discover. In order to learn about dolphins, it is important to discuss where they live, their appearance, and what they eat. Some helpful words to understand are “dorsal fin”, a dorsal fin is the top pointed fin on the dolphins back, “flippers”, a flipper is a flat fin that dolphins use to swim, and “echolocation” is a tool dolphins use to find food by sounds bouncing off of objects (dictionary.com).
