...waste our life-line. According to "Why Conserve Water?" (n.d.) “Only about ten percent of waste water is disposed of properly”. We do not have an endless supply of water. We need to learn to conserve our water now for the future; we have as much water on Earth now as we did when it was created. Limnologists (freshwater scientist) they help us to understand what is going on in the water, like if it is clean enough for consumption, and this depends on what types of organisms can live there. Elder (n.d.) “Each type of living organism has a “preference” or “limits” of water quality. Water quality is measured by analyzing the non-living, or abiotic factors. Some of these factors are pH, temperature, dissolved oxygen, total dissolved solids, turbidity, and stream flow.” When you think about the impact humans...

...fences were destroyed, Caroola Farm has come a long way in restoring and rehabilitating the land so that it can be used for agricultural purposes, through the use of sustainable practises. At the Home Farm, the emphasis in rehabilitation work is their specific focus on rehydrating the landscape through sustainable practises. This land is then used by Mulloon Institute to further research which methods are the most effective. 2.0 Background Land is Australia’s greatest asset, though increasing human activity is resulting in soil loss at a greater rate than nature’s ability to replace it. This process is known as land degradation, which refers to the decline in quality of the land. Land degradation is a current geographical issue, because it affects agricultural and pastoral activities. It causes the decline in the quality of the land which negatively impacts the land’s ability in producing crops, feeding animals and renewing its natural vegetation. However, as land continues to degrade at an...

...ENVIRONMENTAL IMPACT REPORT Mangrove ecosystems play an integral role within the stabilisation of coastal intertidal soil by preventing coastal erosion through their complex network of roots (“Teaching about Mangroves, 2013”). Scientifically they are defined as an assemblage of unique tropical plants which are able to survive within variable flooding conditions and withstand high salinity concentration. They do so by a selective combination of structural adaptations such as salt excretion upon leaves, and filtering of absorbed nutrients (“Encyclopaedia of Earth, 2013”). The most healthy and abundant mangrove communities occur in tropical and subtropical areas, between 30o N and 30O S latitude (“Encyclopaedia of Earth, 2013”). An example of a mangrove community presents itself within the Moreton Bay Mangrove community located within South-East Queensland, Australia. The community possesses 8 mangroves species but is predominantly dominated by Avicennia marina (Grey Mangroves) and Aegiceras corniculatum (Black Mangrove) (“Moreton Bay Mangrove, 2013”). The Moreton Bay community provides vital protection and food source for various marine and terrestrial species including wading birds, shrimps and crabs. Structurally it is comprised of coastal environments consisting of numerous river estuaries that extend seaward (“Moreton Bay Mangrove Species, 2013”). 1. BIOTIC INTERACTIONS IN THIS MANGROVE COMMUNITY The biotic interactions...

...What is dissolved oxygen? Dissolved oxygen alludes to the level of free oxygen not bonded to any existing molecule in the water or other liquid substances. It is an important parameter in assessing water quality because of its influence on the organisms living within a body of water. In limnology (lakes studies), dissolved oxygen is a crucial factor second only to water itself. A dissolved oxygen level that is too high or too low can harm aquatic life and affect water quality. Non-compound oxygen, or free oxygen (O2), is oxygen that is not bonded to any other element. Dissolved oxygen is the existence of these free O2 molecules in the water. The molecule of oxygen bonded in a water molecule (H2O) is in a compound and does not count toward dissolved oxygen levels (Rivsbech et al., 1988). Dissolved oxygen from the atmosphere Dissolved oxygen goes into the water through the air or as a byproduct of a plant. From the air, oxygen can slowly diffuse across the water’s surface from the nearby atmosphere, or be assorted in rapidly through aeration, whether natural or man-made. Water aeration can be brought about by wind (creating...

...Comparative examination of different samples of portable water sources of water in Dhaka city was carried out with a view to assess the different sources of water and determine the water quality of the different sources. The sources of water examined are MUM drinking water, NSU drinking water, NSU tap water, distilled water, Pepsi and waste water. Many parameters were taken in consideration to test the water including physical conditions such as smell, color, turbidity and chemical conditions such as pH, DO, E.coli, TDS and NaCl present in the samples. Finally, a comparative analysis was done to assess the water quality of each samples based on the results from the experiment done. INTRODUCTION Importance of Water: With two thirds of the earth's surface covered by water and the human body consisting of 75 percent of it, it is evidently clear that water is one of the prime elements responsible for life on earth. Water circulates through the land just as it does through the human body, transporting, dissolving, replenishing nutrients and organic matter, while carrying away waste material. Further in the body, it regulates the activities of fluids, tissues, cells, lymph, blood and glandular...

...from rainfall and stormwater runoff. The quality and quantity of stormwater is affected by all the alterations to the land--mining, agriculture, roadways, urban development, and the activities of people within a watershed. Watersheds are usually separated from other watersheds by naturally elevated areas. | Why are watersheds important?Watersheds are important because the surface water features and stormwater runoff within a watershed ultimately drain to other bodies of water. It is essential to consider these downstream impacts when developing and implementing water quality protection and restoration actions. Everything upstream ends up downstream. We need to remember that we all live downstream and that our everyday activities can affect downstream waters. | Watershed ManagementManagement of the environment has been primarily focussed on specific issues such as air, land, and water. Most efforts have resulted in decreasing pollutant emissions to air and water, improved landfills, remediation of waste sites and contaminated groundwater, protection of rare and endangered species, design of best management practices to control water and contaminant runoff, and much more. What is still a continuing problem for our waters are nonpoint source pollution and habitat degradation. These are the problems that are responsible for most of the water quality use impairments throughout. These are typically complex problems that are difficult...

...and supplies, economic, social, and political characteristics which make it a unique and challenging natural resource to manage. Water resources refer to the supply of groundwater and surface water in a given area. Water resources may also reference the current or potential value of the resource to the community and the environment. The maximum rate that water is potentially available for human use and management is often considered the best measure of the total water resources of a given region. With two thirds of the earth's surface covered by water and the human body consisting of 75 percent of it, it is evidently clear that water is one of the prime elements responsible for life on earth. Water circulates through the land just as it does through the human body, transporting, dissolving, replenishing nutrients and organic matter, while carrying away waste material. Further in the body, it regulates the activities of fluids, tissues, cells, lymph, blood and glandular secretions. An average adult body contains 42 litres of water and with just a small loss of 2.7 litres he or she can suffer from dehydration, displaying symptoms of irritability, fatigue, nervousness, dizziness, weakness, headaches and consequently reach a state of pathology.

...Environment and Earth Sciences at Duke University for funding my research. -2- ABSTRACT In the United Arab Emirates, Dubai is building three colossal artificial islands— each in the shape of a palm tree—in the Arabian Gulf. This has prompted several other Gulf countries to construct artificial islands. To determine the impacts of the first of these Palm Islands, The Palm Jumeirah, I traveled to Dubai and interviewed governmental agencies, environmental groups, and the developer’s environmental scientists. I analyzed the island’s impacts on marine wildlife as well as the developer’s mitigation efforts and the developer’s compliance with the relevant environmental laws. The Palm Jumeirah has buried and asphyxiated wildlife, increased turbidity, and changed the alongshore sediment transport. It has also created habitat along its rocky breakwater and within its lagoons. The developer has implemented several environmental mitigation measures, and has generally adhered to the Equator Principles. However, the developer missed a few important opportunities to mitigate. Also, due to political pressure and legal loopholes the developer has been...

For portable/emergency water purification, see portable water purification. For industrial water purification, see deionized water. For distilled water, see distilled water. For the treatment of sewage see sewage treatment Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids and gases from contaminated water. The goal is to produce water fit for a specific purpose. Most water is purified for human consumption (drinking water), but water purification may also be designed for a variety of other purposes, including meeting the requirements of medical, pharmacological, chemical and industrial applications. In general the methods used include physical processes such as filtration,sedimentation, and distillation, biological processes such as slow sand filters or biologically active carbon, chemical processes such as flocculation and chlorination and the use of electromagnetic radiation such as ultraviolet light. The purification process of water may reduce the concentration of particulate matter including suspended particles, parasites, bacteria,algae, viruses, fungi; and a range of dissolved and particulate material derived from the surfaces that water may have made contact with after falling as rain. The standards for drinking water quality are typically...

UNIT ONE: ORIGIN AND CONCEPTS OF ENTREPRENEUR AND ENTREPRENEURSHIP Objectives: At the end of this unit students should be able to; Compare and contrast the various definitions of Entrepreneur and Entrepreneurship. 1.2. Differentiate between Entrepreneur and Entrepreneurship. List five contributions to the study of Entrepreneurship. Introduction Businesses are any undertaking created for the purpose of creating utility. Utility is simply the satisfaction derived from consuming certain goods and services. Businesses are created by a special kind of labour which is also referred to as the entrepreneur. Entrepreneur is regarded as a special kind of labour because not all labour possesses entrepreneurial abilities which enable them to start a business from the scratch. Thus, entrepreneurship is simply the establishment of a new business or business enterprise or venture. This Unit looks at the development of the concept of entrepreneurship and the various ways in which this concept can be defined. Quick Review questions I.
