* Madagascar and the Indian Ocean were once a place of high plant and animal diversity and population however, in the last 1500 years people have come into this untouched environment impacting these species due to their lack of knowledge on human involvement. 3. Choose five examples from the passage and explain why each would be of interest to conservationist. * About 150 species of birds are only found on these islands
And although they offer financial and technical support, there are still problems on the Northern Beaches coastline. The erosion on Collaroy Beach is one of the worst cases in NSW, and without efficient action the problem will only get worse. In 2002 the Warringah council proposed to build a seawall on the beach. This was met with much criticism from the community, mainly due to the fact that a seawall would destroy the beaches natural beauty, something that no one wants to see. The designs for the sea wall cost roughly $100,000, and to build the wall would cost upwards of $11,000,000, of which 40% would be paid by the homeowners of Collaroy.
Te mangrove ecosystem is dissimilar to the coral reefs in that it is more so on land than the submerged reef further into he water. Mangroves have a lower concentration of Oxygen, more opaque water, and more vegetative biomass than coral reefs. These factors make unintelligent tourists cringe at the idea of keeping these bogs. Wetlands act as a filtration systems for the silt that drifts toward the coast which would otherwise “...clog the coral nutrition tracts and destroy the reef”(Moyers, J.D.). This illustrates the vitality of the re-location of the planned sites of the hotel chains even further
There are no clear answers as to how much humans are exposed to Malathion, it is used in areas where the temperature is hot, and mosquitoes are abundant. To date, no government agencies have reported that Malathion is danger to the environment, or humans; they have however put polices in place to protect how much people are exposed. As of now the risk characteristics of Malathion is low, but that could change if someone with no regard for human life get a hold of a huge quantity. In order to protect Americans, Malathion is registered with the environmental protection agency. The risk of toxic exposure to Malathion is minute, only a small application is used per acre placed on ground.
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.
Unfortunately many of these predators are rare or absent altogether in Pennsylvania and can only be seen in areas least affected by human development. Animals such as the lynx and eagle have not been able to sustain life in the redeveloped landscape that has become Pennsylvania. As this country was colonized by European nations and their animals were introduced into the native ecosystem of our land it disrupted the balance and drove off these species. Humans have become the top of the food chain now and has changed the nature flow of energy somewhat to suit our needs. The effects of human development have polluted the waterways of the state as well, making it difficult for native fish to survive long enough to breed.
An invasive plant is a non-native plant species that has escaped cultivation, is spreading on its own and causing environmental or economic harm. • Non-native Invasive plants can outgrow, replace, and otherwise destroy our native plants. That's because non-native plants usually do not have their natural enemies -- the diseases, insects and other environmental stresses -- that keep them in check in their native ranges. • The destruction and replacement of our native plants has several significant consequences: • Our natural biodiversity is destroyed; • Our native plants can be eliminated; • Our wildlife have evolved to use native plants are not able to make use of non-native plants. As a result, they leave the area or die off; • invasive plants can completely fill the water column or cover the
Africa and Florida’s environment both have issues and damages. The damages of the environment affect the animals that live in the area. Florida is known for its pollution in certain areas and this is what hurts the animals, from ranches and farms polluting the watered area where animals live they die off because of what is thrown in the water. In 1990, Florida Legislature banned drilling. This drilling happened on the coast-line with this happening most drilling comes with oil and with oil in the way of an animal they’ll get covered in it and soon die.
(21 marks) The massive increase in productivity and the technology of modern society’s resources, in more developed countries, have created new risks. Many of these risks involve harm to the environment and its consequences for humanity, such as global warming caused by greenhouse gas emissions from industry. Green crime is seen as a global crime because it is harm done to other species or aspects of the environment such as the air, water supplies, the ocean and the rainforest are increasingly seen as impacting negatively on the quality and future of human life wherever it is in the world. Also, It is carried out by powerful interests particularly TNCs with the corporation of nation states and local wealthy elites which another reason why it is a form of global crime. A more radical approach to green criminology starts from the idea of harm rather than criminal law.
The sedimentary salt concentrates because of lack of freash ocean swell water. (Morey-Gaines,1980 pp.213,217-220). So, there is too much of the bacteria that plankton eat, and nothing to eat the plankton. So as they die, they release a terrible odor. The water quality is so poor, fish and sea mammals rarely come into the harbor.
