This are all situated in the Sydney Olympic Park.The Parramatta River flows through the Homebush Bay and is home to many species of birds and fish. Sydney Olympic Park was in the top 5
Many of the aquatic invertebrates are responsible for keeping the ecosystem clean by feeding on litters. Extinction of theses invertebrates would totally disrupt the balance of the ecosystem. The aim of this study is to bring awareness about the harmful impact global warming has on the local aquatic invertebrates and on the ecosystem at a global scale. The hypothesis for this study is that the biotic diversity of the slow moving water and fast moving water are driven by abiotic factors. To support this hypothesis, three predictions were made.
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.
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.
Firstly, the Everglades are an important ecosystem which reduces flooding and replenish aquifers but human actions are having a huge impact on the landscape. The rapid urban and agricultural development in the area has decreased the size of the wetlands dramatically which affects the organisms found there. This is especially important as it is home to several endangered species. Not only that, but invasive species that threaten existing wildlife by preying on or competing with them. According to Everglades.org, they’ve “contributed to nearly 70 percent of extinctions in the United States” and are the “primary cause of species endangerment.” The water itself is a major cause of decline to the area, firstly because of poor water management leading to water levels being too low or too high at the wrong times has caused a decline in many species.
The original inhabitants of the island, Arawaks (Taino Indians), were treated badly and enslaved by the Spanish and as a result most of them perished from the treatment and the diseases brought to the New World by the Europeans. Many historic sites still remain from the original settlement of Santo Domingo. The Spanish legacy continues in the form of personalismo, the worship of leaders and this is often given as a reason for the difficulty in true democracy taking hold in the country. Dictators, throughout most of its history, have ruled the Dominican Republic. About 60% of the Dominicans are of mixed Caucasian-Black descent, about 35% are black and 5% are white (Pariser, 1998, p. 55).
In South Africa water is used out to its limit, the pollution comes from traffic associated with crude oil transport from the Arabian Gulf which is contaminated from tanks that spill oil. Some ways we pollute the Everglades, is because of some of the stuff that goes down the drains. Most of the stuff goes into a lake, pond, or canal, most these are connected to the ocean and Everglades. We have to watch what we let go down the drains, such as chemicals, and trash. I think if we make a way where trash that goes down a drain can be separated from the water and goes into another drain leading to a dump.
Many tropical birds from South America can be found here. Palms, subtropical woodlands and even citrus trees grow here. The Rio Grande delta (the land at the mouth of the river, where it flows into the ocean) once had an extensive palm forest. The Spanish explorer Alonso Alvarez de Pineda first named the river the Rio de las Palmas, "River of Palms," in 1519. The fertile land along the Rio Grande River has given rise to many farms.
However, those that negatively influence the environment should be controlled at early stages. Cane toad being amongst the invasive species have increased spreading in Australia that have resulted in the adverse results from the intended ones thus calling for the control measures to carried.

Biodiversity may also be reduced if invasive species, such as the zebra mussel or golden algae, are introduced into a waterbody during the drilling process. During the drilling process, wells for drinking water may become polluted with a variety of contaminants, such as methane gas. Here I have a video showing exactly what the drilling is doing to peoples water supply. Gas wells require miles of roads and pipelines to move the natural gas from the drilling site to the market. Construction of these transportation corridors can break up the natural landscape and impact wildlife habitat.
