Aquatic ecosystem

strategies/methods have been implemented to reduce these negative impacts?” INTRODUCTION: Stretching over 3000km along Australia’s eastern coastline, the Great Barrier is a national and global treasure which is classified as the world’s largest reef ecosystem. The Great Barrier Reef is a world heritage area, comprising the Great Barrier Reef Region in addition to Queensland internal waters and islands within its boundaries (see figure 1). The area is currently managed as a Commonwealth Marine…

The Susquehanna River is home for many: animals, fish and people alike. It is also a key contributor to the Chesapeake Bay, being the largest tributary within the watershed. The pollution of the Susquehanna directly impacts the health of the bay. To understand the importance of the river to the bay, it is necessary to understand what is causing pollution and what solutions can be introduced to lessen the negative impacts. Pennsylvania is a large participant in rural farming as well as urban…

Humans use resources without thinking of the consequence that it might or will bring. Although renewable resources are continuously being produced by the earth, everything eventually has its limits. For example, Global warming is a major issue in today’s society, ice is melting and the ozone hole is expanding due to pollution caused by our population. Our societies actions are starting chain reactions without accepting the we are the producers. The population is not aware of the damage we are…

Introduction Western Port Bay is a coastal region located in the south of Victoria which opens up into the Bass Strait. It is one of the most biologically diverse areas in the state, being home to x amount of species of flora and fauna. Westernport Bay has a coastal climate, with high rainfall and mild temperatures when compared with the rest of Victoria. The purpose of this fieldwork investigation was to explore the social, economic and environmental impacts of climate change on Westernport…

whales from toothed whales. Whaling is definitely affecting the world's ecosystems. It has decimated the great whale population, especially in the southern hemisphere. The whales are vital to the food chain, stabilizing the food flow and maintaining a healthy ocean so the rapidly decreasing number of whales are going to have major effects on the ocean's ecosystem. Whales are considered to be "cetaceans which means various aquatic life chiefly marine…

Throughout my entire life I have been involved with agriculture. My father is a corn and hay farmer with a few cherry orchards; my grandpa raises beef cattle which we should show at the County fair every year, and now my husband is a Dairy Farmer. I felt like my knowledge relating to issues in Animal Agriculture was pretty broad coming into this class, but as the term has progressed I’ve noticed that I was pretty bias to a lot of issues, as well as having limited knowledge on certain subjects.…

in maintaining the essential biological and ecological balance. There has been increasing amount and the various kinds of waste products which originates from expanding technology but with not much knowledge about how these might react with the ecosystem and disrupt our well being. Types of Pollution Observed in Marine Pollution: o Acidification – Oceans act as natural Carbon Sinks. They absorb CO2 from atmosphere. As…

have been recorded for many years and the rate of stickleback caught in the 1990's is double what is being caught now. Mating occurs in early spring and summer for these fish and it starts with the male building a hollow nest with seaweeds or aquatic plants. After much cajoling by the male, the female lays her eggs in the nest and the male takes over parental duties, guarding the fertilized eggs and fanning them with his fins to provide them with oxygen. This is essential to the survival…

In recent years, global warming has been receiving a great deal of media attention around the world due to its substantial impacts on human life. Although the idea of coexistence between climate change and humans appears reasonable, this cannot be viewed as the ultimate approach to combat climate change. There are a variety of reasons why the coexistence is fraught with pitfalls. First, climate change, according to many environmental activists, is largely shaped by human-caused geoengineering…

The crayfish need an “internal or external canister filter” in their fish tanks to provide the prime environment for growth (Pierce n.d.). A canister filter continuously cleans the water within the tank to maintain the ecosystem for the crayfish. An internal canister filter hangs inside on the glass tank, while an external canister filter hangs outside on the glass tank. These canister filters are the best option for a fish tank because, without them “20-30% of the water” in the fish tank would…
