Essays on Marine Environment

Human industrial activities, production, and by-products of globalization as a result of human development provide negative local and global impact on the marine environment. Thus, human-generated materials interact with the marine environment, they include persistent organic pollutants, polycyclic aromatic hydrocarbons, brominated flame-retardants, organometals, and numerous pesticides (Crain, 2009, 40). Globally, they negatively impact the coastal marine environment; industrialization results in pollution from toxins or fertilizers, overharvesting, and disease. Unfortunately, habitat loss entails the complete removal of the ecosystem and its services (Crain, 2009, 40). On the other hand, the conversion of a system to a different habitat type will ...

The General Assembly of the United Nations has stated that “Changes to the climate, brought about by increasing levels of greenhouse gases in the atmosphere, will thus lead to changes in the oceans, including sea-level rise and ocean acidification, which will put marine ecosystems and coastal communities at risk. Most of these changes can be attributed to human activities and will negatively affect the animal inhabitants of the marine environment. Some effects of global warming on marine animals include changes in distribution, reduction of habitats and reductions in diversity and sex ratios. In the last hundred years, the rate ...

Introduction

Seagrass beds are amongst the most productive marine habitats and their wide-ranging distribution. They provide homes and food sources for many marine animals, prevent erosion and provide nurseries for many commercial and recreational fish species. Despite their importance to the environment, seagrass beds are increasingly being decimated by the results of human activities. The destruction of seagrass beds may have serious consequences on the biodiversity of coastal regions and as a consequence, may negatively impact on commercial and recreational fishing, and ultimately all marine species.

Description of Issue

Seagrasses are flowering plants that live in marine and estuarine habitats. They are rooted ...

Literature review

In the history of the construction of sea structures in oil exploration, load and corrosion together with how those structures will be maintained have always posed a scientific nightmare. Chamberlain, Adam and other authors in a scientific journal illustrate that for a good design of an onshore structure, there should be a right proportion of the ingredients in order for the structure to give maximum life service. They all agreed that in order to achieve this, keen interest should be paid to the permeability, strength, and durability of the mixture. Finally, they added that for effective control of corrosion, ...

The 1982 Draft Convention of the Law of the Sea is a set of rules that governs the use of global oceans, the airspace, the seabed, and the subsoil below. It aims at balancing the interests of nations in controlling activities off their own coats and the nations’ interests in protecting their liberty to uses the waters without interference. The Convention addresses several issues such as exploitation and conservation of ocean resources, navigation and overflight of the oceans, marine scientific research, and protection of the marine environment (The United Nations, 2011).

The Bush Administration asked for this law to be ...

Water can be considered one of the most vital resources in the planet because of its benefits to every aspect of life. Aside from being used for drinking, water ensures that life is continously sustained around the planet. However, as mankind continues to grow, supplies of critical resources like water are slowly drying out due to various causes. While a majority could argue that it is due to the changing climates causing extreme heat, there are others saying that the reducing supply for water is because of pollution. For countries like the United States, issues regarding water supply and pollution ...

Introduction The International Maritime Organization is one of the many branches formed after the birth of the United Nations. It was originally known as the Inter-Governmental Maritime Consultative Organization when it was first established in Geneva in 1948; the International Maritime Organization (IMO) retained that name until 1982 when ...

Human interventions in stopping various occurrences in the marine environment are common; in fact, humans have been reusing to reverse as many problems in the environment as possible. Some professionals argue that, “No matter what actions are taken in the future, these problems will persist because they’re natural occurrences and are not related to human intervention.” One wonders whether this statement is true as it suggests that human actions are natural in the environment and, therefore, any attempts to control then are acts in futility. I believe that the human interventions are increasing the depletion of the ...

The Great Pacific Garbage Patch

Section: Introduction The growing concern of the world to global warming can be traced back to pollution. One of the most apparent is water pollution which affects three-fourths of the whole world. The ocean is where most of the human waste, be it intentional or unconsciously, goes. This waste is called marine debris. It does not only include human waste, but also the natural waste occurring in the environment which escalates as the degradation of the bodies of water continues. According to (U.S. Environmental Protection Agency, 2011), marine debris is any persistent solid material that is dumped ...

Captive Breeding of Marine Mammals: Challenges and Mitigating Measures

Introduction The growing demand to sustain the current lifestyle of the human population puts an added strain to the natural resources of the world. The increase in the exploitation of tropical forests and marine communities leads to a series of habitat destruction thereby leaving thousands of species of both terrestrial and marine animal homeless (Soule et al., 1986). Since 1986, there are already about nineteen percent and nine percent of the world’s mammals and birds respectively that are bread by zoos as per the International Zoo Yearbook Census. Based on the International Species Inventory System, there are about ...

INTRODUCTION

The research capitalizes on the condition of coastal marine environment due to eutrophication (Gray, Shiu-sun Wu and Or). This process of enrichment that is suppose to foster growth to marine and aquatic life is believed to have an adverse effect due to the disturbance that it creates in the marine system. According to the authors, eutrophication facilitates for excessive nutrient absorption of most aquatic plants and microorganism. As a result, it increases the rate of sedimentation that results to hypoxia. When this happens, fishes and other marine life forms do not receive sufficient oxygen. Malabsorption of oxygen stags growth. This ...

Kuwait Fire

Kuwait faced a huge challenge in the year 1990 where the worst oil pollution occurred. This incident was brought about by the invasion of Iraqi troops which damaged the environment and the health of human beings. Oil is major contributor in the GDP of Kuwait as it leads to major revenue and employment. The war on between Iraq and Kuwait brought about major effects to the environment and victims (Baase, 2012). It also brought about constraints against the people involved by creating laws and sanctions. It was an incident where seven hundred and eight wells of oil were destroyed in ...

Introduction

Our knowledge of ocean life is limited to big fishes and salty water. However, with new discoveries it is now evident that ocean life is mainly kept in balance by microorganisms. Billions of micro, nano and singular celled organisms called planktons are the primary producers of the marine fish web. Any living being in order to survive needs energy in the form of food and on earth the sole supplier of energy is the Sun. Be it ocean food chain or terrestrial food chain it always start with the sun. In case of terrestrial chains plants and weeds are ...

Environmental sustainability

Abstract Information Technology has played a major role to reduce carbon emissions. Saudi Arabia and Australia have played a major role through Information Technology to combat the climatic change. Both countries have the potential of new information technologies to reduce carbon emissions. Almost 2% of the global carbon emission is estimated to be from the sector of information and Communication Technology. This is the same as the carbon emitted by the fuel consumed in airline industry. Information Technology has helped to reduce carbon emissions across other sectors as well. These new methods include intelligent systems for cooling data centers, which ...

Plastic particles are in the developing and developed countries becoming an alarming cause of plastic pollution. Theses particles consist of micro-beads, nurdles from cosmetics products as well as the breakdown matters of plastic litter. Nurdles are plastic resin pellet which are intermediary goods used to manufacture plastic products are typically less than 5 mm (0.20 in) in diameter usually find their way to the numerous streams which neighbors the plastics manufacturing factories where they cause plastic pollution which is termed as Mermaid's tears.

For decades, there has not been much investigation or discussion about the plastic bottles and the ...
