METHODS Freshwater ecosystem is also known as aquatic ecosystem that are contrasted with marine ecosystems and high salt content. Freshwater habitats are classified by different factors such as temperature, light, penetration and vegetation. In this assignment, the freshwater ecosystem that was analyzed covered two sites which were the freshwater river at the Gombak Forest Reserve and the Sungai Gombak along the residential area. From both site 1 and site 2, the environmental conditions and invertebrate’s
severity of the increase in agricultural activities, creating concern on freshwater pollution because these activities are inevitable. On one hand, this is an essential detrimental cycle, so it is inevitable. On the other hand, with the advancement of technology and new ways to prevent water pollution , is pollution really inevitable ? “Agricultural activities" refers to the systematic raising of
2005, it was reported that there is “irreversible loss in the diversity of life on earth, with some 10-30% of the mammal, bird and amphibian species threatened with extinction, due to human actions.” (Millennium Ecosystem Assessment, 2005). LESS TALK ABOUT BIODIVERSITY – MORE ABOUT ECOSYSTEM SERVICES IN GENERAL According to the 3rd Global Biodiversity Outlook (GBO-3), (2010), the 5 main causes of biodiversity loss are: 1. Habitat loss and degradation 2. Climate change 3. Excessive nutrient load and
reservoir is built, it is likely to change the natural way of operation of the entire ecosystem around it. River systems are interconnected hence, when a process takes place upstream, it can affect the condition around the downstream. Thus, the construction of a dam can cause significant disturbance to the whole ecosystem of the river. Loss of aquatic biodiversity takes place that hampers the balance of marine ecosystem, both upstream and downstream. Inundation occurs in upstream of the dam which results
Informative essay The Great Barrier Reef, located in the Coral Sea (Queensland, Australia), is the world’s largest living reef ecosystem; it is formed by 2,900 coral individual reefs and covers approximately 344,400 square kilometers, eastwards from the Queensland coast. (Queensland Museum, 2016) It stands out from other reefs not only because of its size, but also because it forms one of the most biologically diverse regions in our planet; it has over 1,500 species of fish, 400 species of coral
population, and a rapidly decreasing glacier mass will lead to severe freshwater shortage in the near future (some places like those surrounding the Himalayas are already facing a crisis of such a shortage, especially in the dry
an abundant and limitless supply of food resources, the destructive impacts of fisheries have now come to light. It is becoming clear from decades of fishery activities that these practices are highly detrimental to the aquatic environment, be it freshwater or marine. Furthermore, fisheries are noticing declines in the abundance and variety of the fish and invertebrates that are harvested. This is not only due to overexploitation but also physical and ecological damage to the fishery environment (NOAA
Research Essay Intro: Constantly individuals take advantage of the world typically unknowingly and unwillingly. On average the common individual has a much larger economic footprint than they would imagine. Additionally, with roughly 7 billion people living on earth the little impacts made each day against the Earth are much more impacting. A large amount of the important issues are the simple things that are done daily that just add up. A significant portion of society doesn’t think twice to
In the past few years, scientist have put the numbers of our ever-growing human population under a magnifying glass. There has been a substantial amount of growth and It 's leading to overpopulation. “Overpopulation is an undesirable condition where the number of existing human population exceeds the carrying capacity of Earth.” (Overpopulation) There are many causes for concern when viewing the numbers and effects because the overall population will suffer shortages of basic needs such as food,
Before we begin to assess the differences and similarities of ecosystems at various levels of health, it is important to understand, firstly, what is meant by ecosystem health, and secondly, what causes a change in ecosystem health. Ecosystem ‘health’ is not judged by the degree of naturalness of a system, but rather on a system’s ability to maintain and renew itself (Bertollo 1998). Ecosystem health has been defined as including the following: homeostasis, the absence of disease, diversity or complexity
