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).”
The first cause of the marine extinction is coming from over-fishing and commercial fishing. According to Marine Extinction and Conservation, commercial fishing has resulted in the collapse of about a thousand populations that once supplied most of the world’s seafood during the past 50 years (Briggs 1.) In other words, people are taking more fish out of the ocean than it can be replaced by those remaining. Due to over-fishing and its change in the environment, there will be several effects in the genetic and in the species diversity from marine organisms.
Genetic diversity, the first effect of over-fishing, is related to the genes that modify the characteristics and functions contained within...

Fortunately, there are several ways to reduce the pollution and collaborate with the ecosystem and wildlife by doing taking simple actions. Some of those ways have been taught when most of the people were still a child. The easiest way to start this process is by walking or riding bikes instead of driving; motor vehicle remains the most significant source of air pollutants. Another way to help is by conserving energy; for instance, turning off the lights, computers, or other electric appliances can help significantly. Since in modern society it is practically impossible to not drive at all, the last way to help is getting regular maintenance on vehicles; provide an oil change every 6 months, and be aware of when the fuel filters need to be changed according to the vehicle recommendations.

- Introduction The Permian-Triassic extinction event is undoubtedly the largest extinction event the Earth has ever seen. While evidence shows that it occurred over a great amount of time, it was effective in causing the extinction of an incredibly large portion of life on Earth. To such an extent that it took millions of years before any large amounts of biodiversity occurred again. This is why it is also referred to as the ‘Great Dying’. This paper will will analyze the survivability of terrestrial vertebrates compared to that of terrestrial invertebrates during the Permian-Triassic Extinction Event....

- The ocean still remains as one of the important natural resource capital of many nations. The numerous benefits (food, climate regulation, nutrients recycling, etc) particularly the quality of life derived from marine and coastal areas have raised global concern for the adoption of sustainable strategies that will ensure the existence of marine and coastal areas in its natural state with less impact caused by externalities. The natural structure and function of coastal marine ecosystems are faced with a lot of environmental and ecological challenges.... [tags: oceans, coastal marine]

- 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....

- Marine Life About Sea Turtles “There are only seven sea turtle species in the world and only one is listed as threatened” (Global Sea Turtle Network). For over one hundred and ten years sea turtles have been swimming in the seven seas, even though sea turtles survived natural predators, climate change, and the extinction of dinosaurs. Sea turtles face more danger than they did long ago, due to more technology, fishermen finding new places where catching fish is promising, oil spills, and finding out that certain sea turtle parts are very valuable....

- The Permian Triassic Mass Extinction The Permian Triassic extinction was an event of cataclysmic disaster and almost the extinction of all species on planet earth. The Permian Triassic extinction is said to have occurred millions of years ago, geologist have estimated that its occurrences happened about 248 million to 286 million years ago. This rare occurrence of events proceeded the Triassic geologic periods and the Paleozoic and Mesozoic eras. This mass disaster was the largest dissipation of living life on planet earth; it is believed to be even superior to other crises such as the Ordovician and Devonian events and the conclusion of the cretaceous era that came upon the dinosaurs....

- The Permo-Triassic mass-extinction was a key event in the history of the earth. (Paleobiology and Biodiversity Research Group). This has also been informally known as the Great Dying. The Permian-Triassic extinction occurred 251.4 million years ago, forming the boundary between the Permian and Triassic geologic periods. This event was also the last periods of the Paleozoic Era. After so many years scientist still have not found the true cause behind such a horrible event. Some scientist have suggested many possible causes for the extinction such as: severe volcanism, a nearby supernova, environmental changes caused by the formation of a super continent, the devastating impact of a large ast...

- The problem I have chosen is the problem of endangered species. An endangered species is a group of organisms that have a risk of becoming extinct. More than 90% of all species that have ever lived on earth has become extinct. Many reasons for this are habitat loss, predators, too few organisms for sustainable reproduction. Habitat loss is the most widespread cause of species endangerment and extinction. Usually, this is happening because of human activity including deforestation and pollution. Pollution and climate change affect the ecosystem, resulting in rise of sea levels, melting of glaciers/ice caps, and pollution can cause death to many seabirds and and marine creatures living on the...

- In the year 1973, the Endangered Species Act (ESA) was instituted in order to bring attention to the issue of species that are in danger of extinction as well as to provide conservation of species that are endangered or threatened. Currently, there are around 2,245 species that the Endangered Species Act lists as either endangered or threatened throughout the world, many of which are found in the United States ecosystems and a handful that are only found in foreign ecosystems (Ehrlich 12). Because of the considerable number of endangered species, people should be aware of endangered species and help to protect these creatures society, as their unnatural extinction due to our actions and negl...

- Nowadays it is common to read articles in newspapers and magazines regarding biodiversity issues. Human beings have been knowingly and unknowingly destroying biodiversity since their existence. Biodiversity is the measure of the variety of species of animals living in an area. Forests are usually areas with high biodiversity while deserts are the opposite. Human beings have always destroyed biodiversity either by deforestation, or by some other means. Biodiversity depletion is a natural phenomenon.... [tags: species, habitat, extinction]

- There’s a good chance that you have never heard about shark finning, not very many people have. “Finning is the inhumane practice of hacking off the shark's fins and throwing its still living body back into the sea. Unable to swim or pass water across its gills, the shark dies from suffocation, blood loss or predation by other species.” (Kelly 2003) You might be wondering why it should matter to you, it should matter to everyone since the shark is the most important equalizer of the sea. It’s important to realize, that mankind will eventually become extinct next if all of the sharks disappear.... [tags: marine ecosystem, inhumane practice]
