The And Its Effects On The Environment

Economic activity and our environment have been closely linked since man first discovered the concept of trade. In the language of economics, the environment has itself, become an increasingly “scarce resource1”. Since economics is about managing these scarce resources, it will be a useful tool when considering some of the environmental issues facing our planet. One of the major concerns confronting the environment today is the overfishing of the world’s oceans, depleting some species to near extinction. With continued advances in technological and industrial proficiency, fishing vessels are able to fish across the globe, further exacerbating the effects of overfishing. Because the oceans are considered a shared or common

Because the GBR is such a highly visited tourist attraction for snorkeling and diving, there has been a large number of human structures that have been built in natural areas. Every five years, the Australian government publishes an Outlook Report that examines the Great Barrier Reef’s health, pressures, and likely future. “The report is required under Great Barrier Reef Marine Park Act 1975 (section 54) and aims to provide a regular and reliable means of assessing reef health and management in an accountable and transparent way.” The report shows the actions that have been taken since 2009, including the focus on improving the quality of water that runs off the land. The increased freshwater run-off is in direct relation to the coastal development that has occurred since the major bleaching events have begun. The report released in 2009, states that the greatest risks to the Reef are still climate change, land-based runoff, coastal development, and some remaining impacts of fishing and illegal fishing and poaching. The report points out climate change as being the main cause of the destruction or bleaching of the reef (Department of Environment and Energy 2017). Most observers conclude that the climate change is a direct result of human

Since the beginning of time man has shown a desire to alter his physical surroundings based on his perception of inequalities, injustices, survival or even due to his own innovations. Perhaps it stems from the primal instinct to survive and along with that a common theme behind this desire seems to be an effort to make the world a better place, either more aesthetically pleasing, or easier to survive in. Technological advances for human survival and comfort may come at the expense of animals, climate, air, land and sea. Human ignorance often leads to the natural wonders of our world being destroyed due to these technological advances and human arrogance. Humans have wiped out many species that they come in contact with and almost destroyed other natural environments and ecosystems. Along the northeast coast of Australia is a cluster of reefs known as the Great Barrier Reef, the most diverse underwater phenomenon in our world. This natural wonder is not being cared for and everyone needs to take responsibility for what is happening to this reef, especially in adjacent locations and help in as many ways as possible. The Australian Government is responsible for the protection of the natural resources within their country. They need to act as the main spokesperson for the Great Barrier Reef. The government needs to be more proactive because if nothing is done the Great Barrier Reef will no longer exist. Even though it is not just the Australian Government that is to blame for

Humans are killing the oceans, or are they? There are many opposing viewpoints to the controversial topic of human activities effects on the oceans and its ecosystem being displayed on social media. According to Louise Gerdes the author of Endangered Oceans: Opposing Viewpoints It is not difficult to find different opinions (9). There are many different outputs of media that have different points of view and it can be extraordinarily difficult in deciding which opinion to agree with and which experts seem the most credible (9). With so many concepts, various articles, and so much research out there it is hard to get a strong informed opinion about how human activity is or is not effecting the ocean and its ecosystem. Endangered Oceans: Opposing Viewpoints; goal is to help the average reader form an educated opinion or to help strengthen the opinion of the average reader by supplying opposing views in articles about the topic written by credible people. According to Louise Gerdes all of the articles used in Endangered Oceans: Opposing Viewpoints have credible authors. Two of the articles that stand out are “Human Activities Threaten the World’s Oceans and Coastal Regions” by Anne Platt McGinn who is a senior researcher for the World watch Institute (19) and the article “Human Efforts Are Improving the Condition of the World’s Oceans and Coastal Regions” by Frank E. Loy who is under-secretary for Global Affairs, U.S. Department of state (28).

Environmental problems is and has been a big subject during the last couple of years. Global warming is threatening our world and causing damage on the nature and its living being. Michelle Innis in The New York Times, writes an article about how the Great Barrier Reef is threatened by climate change, chemicals and sediment (2016). She describes how the last years have provided evidence of a bleaching reef in Australia and how the behaviors of society and its population is a big factor to it (Innis, 2016). To reduce the problem, the government has set up goals to decrease climate change. However, there seems to be required a lot more to solve the problem.

As if overfishing in the earth’s oceans wasn’t bad enough and little to no time for the fish’s population to reproduce we are slowly exhausting the vast ocean’s natural ecosystem of their wildlife (Dr. Daniel Pauly, Overfishing.org) and with the probable extinction of the sharks bring ruin the entire global economy, with that the number of sea life with decrease exponentially hence our way of life of fishing will become extremely difficult to fish in the earth’s oceans with little to no fish left to catch. Eventually it may become a reality where fishermen may not be able to maintain their basic living lifestyle and millions of people will suffer unemployment with a deteriorating ocean thus the economic foundation will be at risk of

Overfishing is the non-sustainable use of the ocean and its marine life. It is caused when excessive numbers of fish are taken from the ocean. This is a major issue as it leads to the overall degradation to several ecosystems. Already, close to 90% of large predatory fish have died out as a result of overfishing. There are increasing concerns that this may compromise many of the world’s ecosystems resulting in the potential risk of their collapse. This developing issue is affecting the Great Barrier Reef significantly due to the contributing factors including pollution, fisheries and fisheries management.

In last few centuries, the world population has grown in unprecedented amount. The world population has more than doubled in last 50 years, from 3.3 billion in 1965 to 7.3 billion in 2015. Unfortunately, this tremendous amount of growth is now lacking sufficient amount of natural resources. Oceans fish population has declined by 49% from 1970 to 2012 and according to recent study, salt-water fish can be extinct by 2048. Economy of Asia-Pacific is heavily dependent on marine resources. Therefore, it is necessary for nations to work together to protect marine habitats and avoid an economic meltdown. No nation can solve the problem of marine sustainability by itself. Without international cooperation now, we will be heading toward a frightful crisis.

Have you ever wondered what would it be like to be a fish in the sea? Well it won’t be so great if humans continue at this rate in damaging the ocean. Many companies, and whole countries, are starting to allow mining and industry in many areas of the ocean. Also, overfishing is a humongous problem in today's oceans; it has killed many species. People must stop doing this much damage to animals species or their habitats, from mining; this could result in a shortage of fish and eventually running out of minerals and medicines that we currently get from the oceans, thus could lead to global disaster in the future.

Their location impacts many things about their culture as they are surviving based on their environment. For food, this tribe relies heavily on hunting and edible plants that grow naturally in the Amazon Rainforest in addition to their personal garden. Due to Chagnon reporting that the Yanamomi are incredibly violent many believed that they were savage hunters. However, only about 15-20% of their food is meat, the rest comes from their personal gardens which are mainly cared for by the women in the tribe. As hunting is mostly done by the men and is not as stable of a food source as agriculture, the Yanomamo are almost entirely egalitarian. While that might not seem intuitive in many indigenous tribes, the groups responsible for keeping

Many animals influence their local habitat by energy and material uptake and waste production while many other organisms changes the chemical balance and alter the local infrastructure. Through a variety of mechanisms, animals are equipped to modify their local community but animals that change a habitat’s structure through the physical process of engineering and consumption of plant material indirectly regulates an ecosystem’s infrastructure and dynamics. (Wright and Jones, 2006; Davidson and Lightfoot, 2008). These engineers increase and shape landscape heterogeneity and biodiversity by creating unique patches of habitat that differ from the surrounding landscape (Wright and Jones, 2006; Davidson and Lightfoot, 2008). While

The financial performance of any business in the clothing retail industry depends on consumer confidence and levels of consumer spending, which is effected by the macroenvironmental factors. Those factors include economic, global, technological, demographic and political and legal forces.

Misallocation, by definition, is the process of incorrectly assigning or allotting something. Without context, misallocation could be no big deal, something easily fixable—just re-assign whatever it was that was incorrectly assigned to begin with. However, in economics, misallocation specifically refers to prices being incorrectly assigned, something that is not easily fixable. In Indonesia, what is misallocated is the price of the forest and all of its resources, which occurs because deforestation results in economic growth, which is only possible because the wrong prices are placed on resources extracted from the forest.

I can vividly remember the moment when I was about to pull the paper towel in the restroom at Cerritos to dry my hands when I recalled the commitment that I had made just a while ago to lessen my use of paper products. Paper products greatly affect the forests increasing the rate of deforestation - conversion of forested regions into a non-forest land for human use and industrial benefits. After a long stare at the mirror, I smirked to myself and turned around, settling my wet hands in my pant’s pocket to let them dry till I reached my class. Although this commitment might just be like a drop of water in a vast ocean, my first effort towards progress is certainly valuable as progress has to begin from somewhere and through someone. Similarly, I have decided to recycle my books and to prioritize purchasing recycled materials as much as possible. Carrying handkerchief instead of using paper towel is another action that I have decided to take. Alongside that, I have also managed to convince my friends to reduce the use of forest resource products and are now clearly aware of the consequences of deforestation. Well-known yet an ignored issue regarding deforestation and it’s effects and it’s need to be controlled in order to maintain a livable environment for all of us convinced me to take a step towards change.
