The Dredging And The Effects Of Erosing At Port Phillip Bay

I hope that I highlighted how critical the Chesapeake Bay is today, and I hope that you agree with me. The Chesapeake Bay is considerably one of the largest resources here in Maryland that benefits not only our beautiful world of wildlife, but our education, economy, and health. Without the Chesapeake, millions of jobs would be lost, millions of gallons of drinking water, and millions of species could face extinction. The Chesapeake Bay

The 2014 Great Barrier Reef outlook report identifies ports as a moderate to major threat to the Great Barrier Reef, and outlines the impacts port activity has, including dredging and dumping of waste, increased risk of oil and chemical spills, and diminished aesthetic values. It also links problems with ports with shipping issues impacting the reef.

Human activities pose a threat to Seagrass beds because of boating, stepping on the seagrass, which damage the root system, dredging, pollution and construction practices.

In order to help save the Bay some changes need to be made, human activity must change, the Bays health needs to become a higher priority and the steps that could be taken to restore the health of the Bay need to be discussed.

Pollution contributes majorly in harming the Australian aquatic ecosystems. Simple examples include throwing rubbish on the streets. As soon as rubbish is left on the ground, it goes to the ocean thought the sewage system and rain. These days, many plastic materials are used and thrown out. Unfortunately, species assume these rubbish as food chocking themselves until they die. Many species are effected this way. Other global pollution impacts include oil spillage. Oil are common these days and which is used as a vital resource. It is common to see oil floating on the surface of oceans. These resources soon effect the ecosystem by polluting habitats of many

With the algae growing so close to the edge or shoreline they are constantly taking in the run-off or whatever may be on the shoreline. This makes it very bad for not just the algae but also the the water and species living down under. A lot of this pollution may come from the big city plants. Their disposals might just be fed right into the Chesapeake Bay and they probably do not care. This is a big problem all over the world, not just the Chesapeake Bay. (Decline of Submerged Plants in the Chesapeake Bay) Another reason to why there is such a decline in not just algae but other grasses is that the warming trend over the last 20 years, global warming. By the looks of it, the warming trend is not going to stop, so this may be a problem to deal with for a longer time. Natural diseases is another way the decline in algae and other grass plants is happening. Mostly dead organisms is the reason for these natural diseases. Once you get a bunch of bacteria and fungi, you will hope to get rid of the algae or grasses because it will most likely just end up making the Bay worse, and turning away species. The number of hurricanes the Chesapeake Bay takes does not help the cause. Hurricanes are affecting the salinity of the Bay. The salinity affects the growth and the amount that grows in a plant as well. (Decline of Submerged Plants in the Chesapeake Bay) The pollution can fall down into the water and you may find pollutants in the sediment. The sediment is home to many species. It can be very protective to large predators and large predators can possibly hide in there while they wait for an attack. Ways the pollutants are getting down there is carelessness by the fisherman and the people in charge of it to take

Also crabbing which is much like fishing, but the crabs take a major hit every year causes a decrease from taking to many of the species at one time. In fact, it is technically illegal to take a certain percentage of females, however this is rarely enforced as pollution is put into the bay Graczyk, et al (2006) found that salinity levels in the water can cause oyster filtration and energy to change dramatically. Over harvesting isn’t the only cause for the oysters decreasing population. The oysters are also affected by watermen who visit each week for recreational and business purposes. Many oysters are silted over due to mid-Atlantic farms, growing cities and the oyster reefs being destroyed by their dredges (Strickland, 2009). The reefs were not just beneficial to the oysters they are a part of the bays life cycle. The oyster reefs also supply homes for small fish and other small sea creatures (Strickland,

The Raritan Bay has over 200 years of waste and chemicals polluting its water to this day! The water that comes through the Raritan Bay is not safe to fish, swim, drink, or

In this project we had to pick an environmental issue in our area and research it. In this project I chose coastal erosion because it was the most common environmental issue. This is a problem because coastal erosion causes many people to lose their home and jobs that live on the coast and if this continues all of louisiana will be under water then nobody will have anywhere to live in Louisiana. This an issue not in just in Louisiana but on most every coastline in the world.

Moreton Bay and Tangalooma is the third largest local government in Australia by population. It covers more then 2000 square kilometres and serving nearly 400,000 residents. The council has more then $4.4 billion worth of assets under management. On March 11th 2009, a container ship in the Pacific Ocean lost over 31 containers overboard, it had leaked approximately 270 tonnes of oil 11km off east of Moreton Bay. Their wasn’t many wildlife that was effect from this oil leak. The animals that were effected was treated, cleaned and then released. In Moreton Bay and Tangalooma over 200 turtles are being reported dead, sick or injured. The debris and plastics in the ocean doesn’t just effect the marine life but it also effects human health. Turtles can be very weak due to their downward facing spines, which causes them to swallow their food easy but cannot bring it back up, which paralyses the turtles gut from digesting their food. Most of the pollution that enter the waterways of Tangalooma and Moreton Bay are being flushed into the Bay’s, which is actually impacting the water quality and health of Moreton Bay and Tangalooma. By more and more pollution entering the water ways of the bay’s it can increase the cause the turbidity, nutrients and algal blooms, which can cause the loss of seagrass and a loss of food sources for the turtles and other marine

The erosion of shorelines is a natural process that can have beneficial or adverse impacts on the creation and maintenance of habitats. Sands and gravels eroded from the shores of coastal bays maintain the beach as a natural barrier between the open water and coastal wetlands. Beaches move back and forth onshore, offshore and along shore with changing wave conditions. The finer-grained silts and clays derived from the erosion of shorelines are sorted and carried as far as the waters of wetlands or tidal flats, where benefits are derived from addition of the new material. However, excessively high sediment loads can smother submerged aquatic vegetation beds, cover shellfish beds and tidal flats, fill in riffle

Australia’s Great Barrier Reef (GBR) is an unparalleled marine ecosystem that holds rank as one of the world’s most valuable natural wonders. The abundance of sea life offers both intrinsic and physical benefits, but unfortunately this extraordinary habitat is now threatened from several different angles. One of the greatest threats to the GBR is the presence of popular shipping routes which surround and penetrate the reef. These ships naturally pollute the GBR, but the severest danger lies in the possibility of wrecks spilling oil or other hazardous cargos. History offers many examples of shipwrecks with outcomes that could have been devastating although there has not yet been a major

In August 14, of 2015, an EPA worker takes a water reading in the Animas River near Durango, Colorado. Once the water was tested, there was an estimate more that 3 million gallons of wastewater in the River. Do you want to know what caused it? An abandon and dormant mine, had a pool of wastewater that had collapsed and went down to the river where we get our fresh water from. Most of the mines from the U.S. have produced 50 billion tons of untreated, unclaimed mining waste on public and private land. Also the ocean is polluted, and estimated 10 percent of the 260 million tons of plastic produced each year-end up in the ocean. The biggest problem that we face today is water pollution, because it affects marine life, reason being, the fishes

When we think about water pollution what comes to mind? have we ever thought about how water pollution affects plants and human life? In this essay i'll talk about in what ways water pollution affects these topics today. Over two thirds of Earth's surface is covered by water less than a third is taken up by land so the condition of the water and how we keep it is pretty important. All living organisms need water to survive on this earth but what happens if the water is no longer clean or usable?

This also isn’t even the only garbage patch there are others all across the Pacific Ocean. Thankfully there are multiple groups that are attempting to help clean up these patches, one of them is called the Ocean Cleanup created by the Dutch. They’ve figure out a way that may work, “...designing a network of extremely long floating barriers that will remain stationary in the water, enabling the ocean to concentrate the plastic using its own currents.”(The Ocean Cleanup)
