The droughts and increased heat has had negative impacts on local aquatic invertebrates. Aquatic invertebrates are adapted to survive in a particular range of temperature and habitat. But global warming makes it harder to survive. This could lead to the extinction of several species of aquatic invertebrates which in turn would lead to serious consequences of the ecosystem. Many of the aquatic invertebrates are responsible for keeping the ecosystem clean by feeding on litters.
Some ecosystems are considered to be a risk. They may be subject to be both natural stress and human-induced modifications. Discuss the vulnerability and resilience of these” at risk” ecosystems. Introduction Ecosystems in the Murray Darling Basin and the Australian Alps; specifically the Kosciuszko National park, are considered to be at risk due to the management of the land and the environment, traditionally and contemporary. A contribution to ecosystem being at risk is from the natural stress and human-induced modification the environment has experienced through years of management.
Location 3 (low tide mark) has many biotic pressures such as wave action, fluctuations in water temperature and predators. Barnacles have many physical adaptations to cope living in this area. They have a tough, hydrodynamic shell, which allows them to withstand the constant pounding of the waves when the tides are high. The shell is also strong to protect themselves from predators that come across the area. In addition Barnacles secrete a cement.
Another thing with hard engineering, going back to the costs is that not all of the countries in the world can afford to have hard engineering management strategies. An example of a place in the world that would benefit from hard engineering strategies but cannot afford it is Bangladesh. The environment is also at risk when hard engineering strategies are used because it can disturb the ecology of the area that it is built in for example fish and animals may be killed because the hard engineering has destroyed their habitat. Some people say that the disadvantages of hard engineering out weigh the advantages but some think the opposite. The main advantages of hard engineering are that for one: they last a very long time and if built well sometimes even for hundreds of years.
This network can be expanded by the addition of secondary nodes. This way you can achieve scalability. Now the downside to this type of topology is, as multiple segments are connected to the network it now depends heavily on the node. If it fails it affects the entire network. This is also not very easy to maintain and the cost for it are high.
Another physical factor is whether the country has space which stores extra water such as aquifer, as this can be something for a country to use if the main water supply does potentially run out. For example Mexico has a low amount of water stress due to having a large aquifer underground, where as Saudi Arabia has a high water stress level because it has no alternative water supply. Climate change is large physical factor which contributes to the pattern of water stress as it can cause climates to become extreme. For example, in Indonesia climate change has increased the amount of
This complex ecosystem is both an extraordinary geological and ecological feature of Florida and encompasses a historic, social, economic, and environmental significance. The IRL is a network of people, places, and natural resources that are inter-dependent upon each other. Unfortunately, the primary threat to this unique ecosystem comes from human population growth as well as coast-line developers. The storm water and sewage run-offs pose significant pollution problems to the ecosystems survival. Today, scientists, and resource managers are concerned about the future of the lagoon, including declines in quality of the water, loss of habitat, biological diversity, invasive species, diminishing fisheries, and the declining of the ecosystem’s health.
The relentlessness of these effects on the larger economy depends on numerous issues, including the disaster itself, the pretentious area and the volume of national and regional institutions to provide relief and begin efforts to reestablish surroundings. When it came down to it, “Hurricane Katrina’s damage affected not only the U.S. Gulf Coast, but the national and global economy as well” (“The Effect of Natural Disasters on the Economy” 1). The disastrous storm restructured the movement of goods and service, the world prices for energy, food trade, building materials to rebuild what have been damaged, individual spending choices, and company incomes. Therefore, “natural disasters always alter the building blocks of economic productions” (“The Effect of Natural Disasters on the Economy” 1). Personal misfortune through injury or death decrease the size and eminence of work in the labor force.
As Urban and agriculture development is needed to meet the needs of the growing population. Engineers have been forced by the rising population to drain areas of wetlands, to make space for development. In this development the clearing and paving of land the precipitation drainage is prevented as well as the water-table not being replenished. The agriculture development has degraded the quality of the water from elevated nutrients such as Phosphorus. These increases have been traced back to application of fertilizer to fields and processing of agriculture and human waste products.
Runoff Quality of the water flowing from the a\land is critical to the reef’s health. The ones near the mainland are the most damaged because of human activities. The land use activities near the coast increases freshwater runoff and the build up of silt. As more land is eroded by human activities the runoff increases destroying the vegetation. Fertilisers, sewage and pollutants can have direct impact on the coral reefs.
