Essays on Marine Ecosystem

Introduction

Climate change is among the significant factors impacting ecological diversity on a worldwide scale. The growth of industries and the increasing human population globally have resulted in a rise in the volume of greenhouse gasses, which scientists have argued are the greatest contributors to the menace. The Florida Keys is one of the ecological treasures of the U.S. that continues to be impacted negatively by climate change and anthropogenic activities. This ecological treasure, which is located at the tip of the state of Florida, comprises about 1,700 islands that stretch for more than 200 miles to the west ...

Introduction In business operations, the supply chain refers to a company’s networks with other businesses or entities. The relationship between a business and other businesses or entities within the supply chain enable the former to facilitate operations and deliver products or services to end users (Lambert 2008, p. 164). Consequently, the relationship between a business and other businesses or entities follow a sequence or order in the supply chain that begins during the procurement and production of goods or products and services until their distribution and consumption by end users (Oliveira & Gimeno 2014, p. 149). Hence, the supply chain is one ...

Introduction

Is the fish population close to extinction? This could be addressed by taking a look at the present trend in the marine and aquatic population. The marine and aquatic habitat house more population and species than the terrestrial. The researches have proved, and made it obvious by the fact that water bodies take up 70 percent of the earth surface. Fishes are the most common species in the aquatic and marine habitat. There are various types of fishes, and each species is important in the food chain. In fact, the depletion of one species can create incredible consequence and effect ...

Introduction In an article for 9 News, the columnist Usher discussed response from various sectors to the Western Australian government’s policy on shark culling. In 2013, the WA government announced its implementation of shark culling as a policy due to increasingly alarming safety issues. Shark culling involves the use of drum lines to bait and capture sharks. Since then, many tiger sharks were captured and killed. Various sectors, particularly environmental activists such as Sea Shepherd expressed opposition against the WA government’s shark culling policy citing issues about its legality. The issue was brought to the WA Supreme ...

Navy Sonar Testing Vs. Marine Life

Sonar is an artificial form of echolocation, which involves the use of sound navigation and ranging techniques for the propagation of sound underwater. This technology is used for navigating, communicating or detecting objects that are under or above the water surface. Specialized sea creatures such as whales and dolphins have the ability to use sound reflected from waves for sensing and locating distant objects or prey, this is called echolocation. Bats also use the same technique to navigate in the dark. Humans also use echolocation through sonar technology in ships and submarines to avoid icebergs, locate ...

Causation of Climate Change

The world’s climate system is composed of five elements that include hydrosphere, lithosphere, atmosphere, cry sphere, and biosphere. It varies naturally with time and is dependent on the incoming and outgoing energy which determine the optimal balance of the earth’s energy. These determinants constitute factors that cause climate variation that result in either warmer or colder states. This result into a phenomenon referred to as climate change. This is a condition, in which, the earth experiences adjustments in its weather that occurs over a period. This essay provides a detailed analysis of the causes, characteristics, and the impacts of climate change ...

There are many limiting factors in a marine ecosystem. These limiting factors interact in many ways to form different features and also affect the marine ecosystem. This paper analyzes the relationship between the temperature of the region and rate of evapotranspiration, the upwelling of water and the speed of wind, the ocean currents and the climate experienced, and nature of rocks and type of features formed. The temperature of the surrounding region in an ocean is very important. When temperature is high, the evaporation from the surface of the ocean would be high (NSIDC, n.d). In addition, high temperature ...

Wind is a major limiting factor in the marine ecosystem. Wind affects waves, dune system, sediment transportation, currents, and weather. Wind has profound effects on the waves. As wind move over the surface of the oceans, the abrasions between the wind and the water surfaces lead to formation of waves. The speed of wind also affects the size of the waves formed. When the speed of the wind is very high, the abrasion between the wind and the surface of the water increases leading to huge waves. In the event that the speed of the wind is low, the waves ...

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 ...

Introduction

A scientific study was conducted to evaluate the effects of crude oil on different nitrifying prokaryotes. The researchers utilized ammonia-oxidizing bacteria and archaea to develop a bioassay. The study evaluated the ecological responses of these two groups of microorganisms on marine oil spills. Researchers found inhibition of nitrite production in all tested ammonia-oxidizing micro-organisms. The paper highlights the impact of crude oil spills on the environment. The paper also demonstrates the effects of phytoremediation to treat the oil spills. Many scientific studies had been conducted to evaluate the effects of phytoremediation (Using Nitrosopumilus maritimus and Nitrosococcus oceani) for crude oil ...

The term pollution in the simplest and most basic meaning refers to the condition, situation and circumstance where harmful and toxic materials and substances find their way to the environment thereby making human life inhabitable and unhealthy. In the recent history and empirical evidence has confirmed that human activities have contributed to pollution to the environment and in effect exposing the human race to danger and threats. They hazardous human activities are evident in the most developed nation in the planet, whereby the industrial refuse are deposited to water bodies. With the above background in mind, marine or water ...

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 ...

Environmental Studies

The term Global warming is used to illustrate a gradual rise in the average temperature of atmosphere and oceans of the earth. Aykut Emre Bozdogan has considered global warming as a change, which is undyingly modifying the climate of Earth 1. Global warming is affecting and will continue to affect lives. The present scorching and burning weather us not merely the nature’s act, neither the progressively volatile and unpredictable weather that is causing havoc in several parts of the world around the globe. The human beings are the cause of global warming and as a result all the living beings are ...

Introduction

Throughout the life of a human being on earth, there is an interaction between each individual and the environment. Each one of us during his lifetime leaves a mark on the globe. There is a variety of ways of how human beings can interact with the Earth. These ways may be of a positive or a negative effect depending on their overall outcome (Paul et al 2011). Therefore, Human footprint can be defined as the measure of human impact on the environment.

How Human Footprint Affects the World Ecology

Following social and economic development, human beings end up consuming very large numbers of a wide range of natural resources from the Ecological ...

Introduction

Whales pose as important components of the world’s marine ecosystem (NRDC, n.d.). Those stand among the most fascinating mammals; they manifest intelligence akin to that of human intellectual capacity such as linguistic communication, with their distinctive nervous system features credited for such (D’Amato and Chopra, 2010, p.1). Nevertheless, whales face threats to their existence due to incessant hunting activities. While the International Whaling Commission (IWC) sought to ban whaling activities in 1986, countries such as Japan and Iceland have refused to abide due to their own reasons (NRDC, n.d.). Japan ...
