The Murray-Darling Basin is facing many environmental, social and economic factors that affect the life around the basin. The Murray Darling Basin is facing many environmental issues that are caused by humans. The farmers near the MDB use fertilisers that run into the water when it rains and pollutes the water. The pollution from the fertilisers cause algae blooms to form. Another way that humans have affected the environment is through the use of irrigation for crops. The use of irrigation…

Discussion: Mudboils cause structural failures since they are suspensions of gravel, clay, silt and fine sand creating an unstable surface. Since the beginning of persistent mudboil activity in the 1970’s, natural landscapes and engineered features have become subject to land-subsidence as mudoils continually deteriorate the areas in their path (Tresohlavy 2003, pp. 27). Petroleum pipeline rerouting, telephone cable burials, and the collapse of bridges have demonstrated the true capabilities of…

THE DIMENSIONS OF POLLUTIONS AND RESOURCES DEPLETION. ABSTRACT In this topic we will look at the dimensions of pollution and resources depletion. For pollution we will get to know the definition of pollution. Rather than that, we will know each types of pollution and each definition of this. Then we will look further into the cause, effect and solution for each pollution in this topic. Lastly we will discuss about the resources depletion effect occur by human activity. INTRODUCTION Environmental…

Agriculture covers thirty-eight percent of Earth’s land surface, but the land has continually been turned into cropland as the world’s population steadily increases (Brennan, Withgott pg. 225). Food is a necessity to human survival, however, agriculture, specifically industrial agriculture has caused multiple environmental impacts. Compared to the other land uses, agriculture causes the most harm to the planet due to the use of inorganic fertilizers, machinery, irrigation, pesticides,…

Freshwater management has been of major concern in New Zealand, particularly during the last two decades. There has been consistent decline in water quality and quantity in Canterbury during this time. Consequently, work has been made to improving the way water resources are managed. This report will discuss the consent conditions for the Lincoln University Dairy and Research Farms, consent number CRC143396, and how the consent is monitored. The Resource Management Act (1991), the Dairying Clean…

they discussed the basics of what a watershed is, who came up with this concept and why, that watersheds are everywhere, and activities that can harm watersheds. A watershed is a unit of land where all the water eventually drains, whether above the surface or below, to a common place or point that is downslope. This common place can be the junction with a larger stream or river, a lake, or reservoir, or an ocean. This water starts off as precipitation and some is lost to evaporation and…

This passage uses a lot of numerical data to clearly point out some possible influences that may be caused by the project. (e.g. “Development of the athletic complex will disturb approximately 68.5 acres and create 8.29 acres of new impervious surface.”). There is a bullet point list in this passage, which makes the modifications of the project on existing structures more straightforward and clear to readers. 3. A) I think section 11.a.ii is a fairly effectively written passage. The passage…

Problem Statement Industries are generated waste water, which contain dyes and pigments in waste water. Characteristically high in colour and organic content (Grag, et al., 2004). Dyes are widely used in industries such as textile, rubber, paper, plastic, and cosmetic. There are many of dyes exist in industries and one of them is methyl red and through nano zerovalent iron removal of dyes from waste water. Dye industry effluents constitute one of the most problematic wastewaters to be treated…

Point source: Built in or settled pollutant discharge facilities. In other words, single and identifiable source of pollution. For example, industrial wastes or certain chemicals such as mercury can be discharged from industrial discharge pipes to rivers or lakes. Waste disposal pipes can be another example. Non-point source: Release of potential pollutants from a range of activities without a single or definite source. Agricultural facilities can be considered as non-point sources. Stormwater…

The water quality of the UHS creek was found to have excellent water quality. There are other creeks, however, that have poor water quality. One way humans negatively affect water quality is by fertilizers and pesticide runoff, mainly used by farmers. Fertilizers and pesticides that drain into a river increases the amount of nitrate and phosphate considerably. This leads to a massive amount of algae growth, known as eutrophication. When the algae die, they are broken down by the bacteria which…
