In 2009, Sylvia Earle gave a presentation in a TED conference on a rising problem that the world faces: the ecologic depletion of the world’s oceans. The ocean accounts for a massive portion of the recycled carbon dioxide back into oxygen, and provides food for huge parts of humanity and for huge numbers of animals. I agree with her conclusions that the oceans are being depleted and this can only mean bad things for humanity, but I disagree with her solution. To solve the problem, Mrs. Earle claims that the United States and other countries should expand their protected zones of the ocean. However, an ocean is not like a land environment, where you can section off parts of America to save isolated habitats. Fish travel often travel and migrate hundreds of miles to find food and suitable mates, this is especially true the larger the fish is. Sectioning off parts of the ocean only solves part of the problem, because the fish in that area will simply swim out of the area and then be caught by fisherman. The only way to incorporate government protection into the oceans, is for the government to effectively own the oceans within its borders and then lease the rights to fish or put quotas on the number of fish that each fisherman can take out.
I find this solution of government protection rarely leads to the desired outcomes. In the American west and in large parts of Canada, forests are protected in much the same way as described above. Loggers are given leases that give the rights to cut trees in a given area. However, this leads to one of the most well known and discussed economic problems when property ownership is taken out of the equation: the tragedy of the commons. The tragedy of the commons is a problem where numerous actors ...

...r example, no sane property owner would allow a trash company to dump their trash on the property where he owns his house. This disincentive will keep profit seekers from harming others property because court proceedings are long and costly. Coral reefs will become popular tourist destinations, for their variety of life and their impressive size. For the same reason that Disney Land is not littered with trash, the owners will seek to protect the reefs in order to keep tourism up. There is also the almost unknown practice of creating artificial coral reefs with sunken ships or other large structures. With this practice and a profit incentive, reef owners could even expand the reef, thus increasing the number of people who can view it at one time. In short, the privatization of the worlds oceans will lead to increased numbers of fish, larger reefs, and a cleaner ocean.
With a coastline of over 202 000 km and over a fourth of the world’s freshwater resources, it is no wonder why Canada’s fishing industry is a huge part of its economy.1 Canada exports more than 75% of its fish to over 130 countries worldwide. Many of the 7 million people who reside on the coast depend on the ocean’s resources. In total, Canada’s entire fishing industry is worth around 5$ billion dollars a year, being one of the world’s most valuable. However, the coasts have not been treated by respect; overfishing, over consumption, and wasteful practices has deteriorated, not only the industry, but the ecosystems and fish populations. This is a huge global issue; the worldwide collapse of fisheries has been project for 2048. Slowly, as the trends continue, we will inevitably see many fish species start to disappear. In fact, the ill-treatment of species on the Canadian border has already devastated a large specie, the cod.
Imagine a lush underwater place. Beautiful structures colorful animals and places that would never have been thought of before. In reality that's not what it really looks like, really the ocean is a desolate place that is barren like a desert. Many marine species have been lost by as much as 49%.(seeker) A big part of that reason is because of coral bleaching which causes as stated above a decline in species that depend on the coral as there home. Coral bleaching is a serious problem that could cause problems for everyone if we don’t fix it.
As long as humans have lived in forested areas, they have cut down trees for lumber and/or to clear space for agricultural purposes. However, this practice has resulted in the destruction and near extinction of our national forests. Today, fewer than five percent of our country's original forests remain (Thirteen) and the U.S. Forest Service continues to allow more than 136,000 square miles to be logged each year (Byrant). Even more alarming, is the fact that only twenty percent of the current public forest lands are permanently protected by law, leaving nearly eighty percent to be consumed by chainsaws and bulldozers (Heritage...).
Wade “The Management of Common Property Resources: Finding a Cooperative Solution propose that collective action is the most effective solution to the tragedy of commons. Moreover, it is cheaper than government intervention and privatization but will it work? Many argued that it is not possible for ind...
Perhaps the most obvious benefit of an artificial reef is the creation of a new community for aquatic creatures to live. It is like a developer going out to sea and making a new subdivision out there for fish. This creation of an artificial reef is the most natural way to protect the marine habitat, by providing shelter, a source of food, and an area for mating and reproduction for a numerous amount of creatures. The reason this is so important is because a given area of water can only support so many marine creatures, none of these creatures can live in mid-water where there is neither shelter nor food. Shelter is needed for resting, mating, caring for young, and many other reasons. Food is also a big deal here, because it turns into an all you can eat buffet at the reef. Now the fish instead of having to swim all over the ocean can now go one stop shopping. This is kind of like a Shoney’s underwater for all the organisms involved. These artificial reefs take a lot of the human pressures off the existing natural reefs, this also usually leads to the natural reef becoming national marine sanctuaries. This all sounds like these reefs are just placed recklessly, but every type of organism is taken into consideration. Some of these include existing coral reefs, beds of aquatic grasses, oyster reefs, scallop beds, existing live bottoms, and habitats of endangered species just to name a few. For the unfinned organisms these artificial structures are needed for the formation of coral. This very important coral cannot grow on sand, so it needs a solid surface to grip onto in o...
Aldo Leopold’s biocentric view of forest conservation shows that the land ethics is “an evolutionary possibility and ecological necessity.” (Aldo Leopold 1949) In Leopold’s words and our current social status, land is considered as property, but not a part of biotic community. In this case, the forestry management in British Columbia is deemed to compete with community, which needs to change into cooperation with community. The process and purpose of conservation education in our provincial institutions; for forests resources have been the main source of income and economic developments for over a century in British Columbia, the government has involved in forestry and land management for years; the conservation system is totally based on economic motivations, people decide whether the species are worth economic value or not. These three existing problems in British Columbia are contrary to the growth rhythm of biotic community and the land ethic.
A big change that has occurred in the oceans all over the world is the Coral Reefs are dying and are predicted to be dead by the end of the century due to the rising acidity of the oceans caused by many different threats to marine ecosystems. Coral reefs cover less than 0.2% of our oceans but they contain 25% of the world’s marine fish species according to Endangered: Biodiversity on the brink, 2010: pg.45). If this is the case that means by the time the end of the century comes around we will have lost close to 25% of the worlds marine ecosystems.

Water pollution has had devastating effects on the environment, which include irreversible effects on the oceans ecosystem. People often underestimate the importance of the ocean. They don’t realize how much damage pollution has caused to the ocean and the thousands of creatures that inhabit it. Earth is a huge place, but resources are actually very limited and will not last forever unless there is a balance. We must protect the resources we have in order for them to last into the next generation.
...eefs helps, but does nothing to prevent runoff from pesticides and fertilizer. Many resorts educate divers about not touching the coral, but it is unrealistic to expect that the coral could not get accidentally bumped. One country could ban pollution, but if the next country doesn’t, what good does that do? It needs to be a global effort if we are to save these “tropical rain forests of the ocean.”
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.

In 1986, The International Whaling Commission (IWC) implemented a moratorium to stop commercial whaling. Many people believe that this would save the whales and end forever the industrial slaughter that had decimated the many different species. Being an animal lover and just getting back from Florida for over a year, I realized how beautiful and important the ocean and the animals that live in it are. In Florida I saw many different types of ocean species, but I have never seen a whale in real life. And that made me think. How protected are these animals? I have watched television programs about entire fleets of ships, and even a helicopter, out following whaling ships trying to sabotage their efforts in order to save as many whales as possible. What are the loopholes that these whalers are slipping through to still be able to kill these majestic creatures?
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).”
