Negative Effects Of Urban Development On The Environment And Natural Habitat Of The Beach

After the dredging in 2009 occurred effects from the procedure were seen within just two weeks, all being negative. Some longterm effects include loss of beaches and marine life. Portsea beach for example is no longer a beach and now the government is spending millions of dollars in sandbags to attempt to stop the beach from degrading even more. Erosion is slowly destroying the coast and

The Cronulla beach environment features a variety of issues that are both physical and human related; the most prominent issues are erosion, inappropriate development and also pollution. However despite the many issues present at Cronulla, there are a variety of coastal management strategies being administered in order to combat these problems that have a potentiating threat on the beach biome. The predominant strategies used to counter these problems are Seabee walls, Seawalls, and also signage, bins and fences; and these five solutions each have advantages and disadvantages, which ultimately prove whether or not, the strategy itself is successful.

The aim of this report is to investigate Long Reef and Collaroy Beach’s coastal management.

The Effects of Human Activity on Coastal Landforms Human activities add another layer of complexity to the natural processes of coastal lands and materials. These activities may have direct or indirect effects on our changing coastlines. They may effect sources of new sediment to the coast and the movement of sediment within the coastal environment. Sediment starvation caused by river and coastal management is one effect of human activities on the coast. For some coastal regions, such as the Pacific coast, a large part of their sediment is supplied by rivers.

Types of human activity that affect the Bay's health. Humans either do not see or do not care about the pollution they send into the water. As humans build more factories close to the water or send more waste out of their homes it goes into the Bay causing many problems for the ecosystem. "waste from people's homes, stores, and offices is also treated and discharged into the Bay and its rivers. " (Chesapeake Bay Ecosystem) People do not understand the effects of pollution the Chesapeake Bay Ecosystem says that people believe the water where the pollution is going will dilute the pollution and won’t be as bad. Humans do no understand the problems pollution will cause. The population of the Blue Crabs in the Bay was below average for over 10 years. From 1998 until 2009 the crab ecosystem was so unhealthy they were unable to live and reproduce.

The Year 10 geography field trip was an insightful experience into the workings and functioning of metropolitan coastlines here in South Australia. The day consisted of visiting various beaches in Adelaide that were influenced by some form of hard or soft engineering techniques that changed the natural processes of the beaches. What was evident from this trip was how much these beaches have been changed to an extent where it is unlikely that they will ever go back to the way they were prior to human settlement.

period of time have increased the size of the beach. Enviromental organisations have tried there best to limit the amount of man made deveoplment on coastal lads and many schools

Ocean pollution is such a broad topic, and one that has many facets to it. As a group, we found it to be a very intriguing topic that it relevant to our everyday lives. As New Jersey residents, we have all spent time at the Jersey shore. We have all enjoyed the small and big beach towns, the sand, and of course

The topic I have chosen for the assignment is the human impacts that are placed on the beaches and coast of Warrnambool, namely areas around the Merri Island Sanctuary. This also incorporates locations including Stingray bay, the breakwater, Shelly beach and Middle Island.

To begin, there are many types of human activities affecting the health of Chesapeake Bay. Residential developments have replaced wetlands, forests and meadows, taking away habitats of the native wildlife. Overuse of natural resources has caused the degradation of foods necessary for wildlife in the ecosystem. Intensive hunting practices have caused the extinction of several species in the area. Soil damage as a result of fertilization has contaminated nearby water supplies, causing damage in the Bay. Point-source pollution as a result of industrial businesses has also

As humanity continues to prosper agriculturally, industrially, and in population, companies, as well as local communities, have obsessively used the Ocean to toss their waste without consequences. The formation of dead zones has been intensified by the increase runoff of fertilizers and the burning of fossil fuels. Enhanced primary production causes algae to bloom at a constant rate creating a layer near the surface. This layer acts as a roof to vegetation below resulting in a lack of oxygen which organisms use to live. According to Robert Diaz and Rutger Rosenberg, “Dead zones have now been reported from more than 400 systems, affecting a total area of more than 245,000 square kilometers, and are probably a key stressor on marine ecosystems.” Specifically, the Chesapeake Bay has been polluted to the point where areas have now been uninhabitable to marine life. Although waste disposal is a difficult issue to solve, polluting bodies of water endangers the marine life, environment, and health of organisms.

Since they were built in the early 20th century, there has been a steady increase in beach erosion. In the 1970s, the government issued a project to replenish the beaches by replacing the sand that had been eroded away over time (Fox). In the 1940s seawalls and groins and even some small jetties were built to protect the properties on the beach. By the time new sand was brought to the beach in 1991 to replenish what was eroded, there was hardly anything left. A lot of the seawalls and groins were buried in order to form the new beaches. The cost of this over the years is well into the millions and although replenishing the beaches with sand is helpful now, it is hardly a long term solution (Fox). There are even implications now as they add more sand. The gradual slope of the beaches before erosion and the replenishment of sand is no longer. The adding of sand from other places to these beaches in mass quantities means that the sand forms steep drops into the ocean in relatively shallow water. This can be dangerous for kids and adults alike who are not careful when in the water

While developing the coastline, may seem economically appealing, it is important to consider the fact that development takes away from California’s environmental value and appeal. Writing letters and putting political pressure on the CCC, as well as state legislators is one of the best ways to motivate policymakers to work to preserve the coastline that makes California iconic. In addition, there are also several organizations, such as Surfrider Foundation, that work hard on local issues, such as beach access and coastal preservation that need your support

I live less than a mile from the San Francisco Bay and Estuary (SFBay). I wrote about this bay’s environmental issues in the Unit #1 Learning Journal assignment and have decided to use this opportunity to elaborate on two specific environmental issues challenging the SFBay.

Cities are having to close more and more beaches. Why you might ask it is because of harmful marine organisms. There are tools that make sure the seafood people eat is not
