Coastal Population And The Marine Environment

How effective are the coastal management strategies used at present in your local beach area?

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

The aim of this report is to investigate Long Reef and Collaroy Beach’s coastal management.

The ocean is two-thirds of our planet a vast blue landscape home to many biomes which according to Boyce Thorne-Miller “(ecosystem types) corresponding to sets of environmental conditions that vary with depth, latitude, and longitude” (16). However, the ocean and its biomes is under attack from the changing environment. We can see this through coral reef biomes as they make their home near the shores. Through coral reefs we can view the effects that these changes have on the ocean through how the coral reef biome is affected. Humans are a danger to the coral reefs and the wildlife that resides in the biome. The pollution being released into the environment is poisoning the coral and causes death and malformation to the wildlife. The ocean is changing due to global warming which is causing a change in the temperature and rising water levels leading to a change in the stabile areas coral can survive. The increasing acidification of the ocean is causing the coral reefs to die. I will be looking at the effects these issues cause to coral reefs biomes and the ocean to see the similarities in how they affect both.

The oceans need to be protected because it is where life began and if not taken care of, life as we know it will end. The well-being of the ocean is constantly being threatened and needs to stop. When dangerous substances go into the ocean, ecosystems suffer and become endangered along with the lives of people and marine life. The importance of protecting and preserving the quality and biodiversity of the world 's coasts must be recognized because they are truly irreplaceable. If humans are not educated , and become careless about what is thrown on the ground or sprayed on lawns, disastrous effects follow when it comes to the condition of the ocean’s ecosystems, which can endanger life itself, leading to a problem only we can correct. There is historical evidence of ocean pollution, although the problem still shadows us today.

* The group is mostly focused on maintaining the vegetation of the various lagoons in the Terrigal area. As a result, most of their actions relate to the maintenance of the lagoons. The kind of things they do include:

Earth's oceans are dying. “About 80% of the ocean around the world is polluted with chemicals industrial and residential waste, all of which comes from the land” (“Marine Problems…”).  Pollution is mainly coming from the people. Marine pollution should be stopped because it is the cause of many problems and if something is done about it, people will see an increase in sea life and healthier waters. It makes its way into the ocean and kills marine life. Ocean pollution is affecting the way of fisherman and their everyday lives. It is also very bad on the community because pollution is very bad on tourism. Ocean pollution should be stopped because it is poorly affecting marine life, it is not good for fishermen, and is very bad on tourism.

Preserving coastlines is important for the economy and the environment. The fact that the business world and the preservation world are on the same page is a good indicator that maintaining beaches are important for both people and animals. The data that has been collected by both parties, thus far will hopefully bring a more cost effective and more long term solution for beach replenishment. So the beach bums and the sea life may continue to enjoy one of the most beloved landscape for generations to

In 2009, Dr. Sylvia Earle wrote The World is Blue to educate and alert the reader about human impacts on marine ecosystems. Through this book she conveys her passion and methodical arguments concerning the importance of the conservation of the ocean, which encompasses approximately 80 percent of the earth’s surface. Dr. Earle states “the ocean touches you with every breath you take, every drop of water you drink, every bite you consume” (17). This statement emphasizes the significance of the ocean, not only for marine life, but all life forms on earth. The book implies that currently in today’s world, the conservation of the ocean requires a global effort to reduce human damage from the past generations. Using facts gleaned from credible scientific resources, she defines the problems of overfishing, bycatch, and pollution. By analyzing human impacts on marine ecosystems, Dr. Earle determines successful and unsuccessful solutions to these problems and suggests various ways individuals can change their lifestyles to reduce impact on the environment as a whole.

Benjamin Halpern and Andrew Rosenberg have differing viewpoints as to whether or not our marine resources can be sustainably managed. Halpern believes this can be achieved if traditional fishing should be limited from marine protected areas to allow maintenance of these fisheries. But when speaking about sustainable approaches for our marine resources with the public there’s a lot of resistance because the public tends to view these areas as excluded. In other words, the public is not allowed traditional fishing, water sports, or other similar activities in those areas. That’s why there are different types of sustainable use and management of those resources. Areas like nursery grounds to protect ecosystems are different from other areas settled for fishing species like the commercial lobster, for example. Some species are set aside and protected until they reach a certain growth so then they can eventually migrate to an area where they can be reached by local officials.

Marine conservation was traditionally focusing on resolving the common issue where commercial activities exploiting shared resources yielded private benefits of employment, economic benefits as well as increased harvests. In this process, resources were over-used (Bulte, et al, p.20). Therefore, a need rose to conserve the common marine resources to yield public goods of biodiversity and ecosystem services that are not taken into consideration by the marine policies. Unless the public goods nature of marine resources is addressed by the marine policies, provision, as well as conservation of biodiversity and ecosystem services will be a dream to achieve, even if other policies like catch shares and top-down command measures are put in place (Arriagada and Charles, p.804). This discussion will focus on the various incentives for marine biodiversity conservation within the typical public good structure.

Our Earth is covered by over 75% water. Every elementary school student in the United States knows that information. But, something that isn’t stated so obviously is that our oceans matter a lot. They play a very pivotal role in the weather, ecosystems, and to even the almighty human. Your average Joe might not see it in his daily life, but up until 1972, individuals and corporations dumped an estimated 100 million tons of petroleum products, 38 million tons of dredged material (34% of that being polluted), and a frightening 89,000 containers of radioactive waste. That is the reason the environmental issue at hand today in this paper is ocean dumping. The reason most of that stopped in 1972 is because of the exact policy that will be discussed. The policy in question is the “Marine Protection, Research and Sanctuaries Act, or MPRSA for short. While yes, MPRSA did solve many problems in regards to ocean dumping, the policy itself is not perfect. The organization, or roadmap, of this paper will be broken down into three parts: background information of the issue and policy, economic analysis of the policy, and personal recommendations to policy makers on ways to improve the policy.

Coastal areas offer a wide range of activities: from recreation, tourism, harbor, fishing, offshore energy infrastructures, power station, road links, conservation, navigation infrastructures, and aggregate extraction. All of these activities are competing to gain access and to use the coastal areas. These activities will interact each other in problematic ways, which eventually can create tension between stakeholders and damage the environment. Therefore a form of management is required to accommodate, facilitate, and bridge all interested parties, their

It was Mihaljo Mesarovic, the author of “Mankind at the Turning Point”, who once said “The Earth has cancer and the cancer is man”. He was definitely onto something. In fact, humans have had a major negative impact on the world’s marine environment. Throughout recent human history, it has been obvious that the wellbeing of the marine environment has been in jeopardy. Pollution of the ocean, overfishing and the greenhouse gases these are all the aspects that can cause the destroying of the precious environments, such as reefs, sea-grass and coastal habitats. According to the essay and interview “Seafarming at the End of the World”, written by Peter Meehan, he presents the fact that human impact on the ocean is the main reason that causes the awful situation of marine ecosystem and organisms.

As the world develops and the human population grows there is more pollution being dumped into the oceans, causing major problems to marine life and ecosystems. Major causes of marine pollution involve non-point pollutants, marine garbage, toxic ocean pollutants and sewage disposal in oceans. From heavy metal poisoning including lead and mercury killing predators such as sharks and whales, to waste getting trapped in the digestive tracts of marine animals, this essay focuses on how human interference causes horrifying problems to the marine life, but also how to fix it. It will also explore the normal activities of people including farming and how this can cause an imbalance in an ecosystem. Everyday activities can cause massive nutrient
