Loss Of Biodiversity In Australia

In this essay, I will be talking about the loss of biodiversity in the southern hemisphere while focusing on Australia and Asia. I'll address what biodiversity is and what constitutes for its loss globally. Next, I'll talk about the increasing decline of biodiversity in Australia as well as Asia and why it's occurring. Then, I'll take a religious approach to the environment and how the loss of biodiversity ties into it. Last, I'll explore how Australia and Asia are trying to combat their loss of biodiversity and what I think we should implement to change it. Biodiversity is the variety of all life forms including animals & plants that can be found either in just one location, or on the whole planet. There are three main factors …show more content…

Australia is home to an estimated 570,000 different species (147,579 described species), giving it more than 5 per cent of the world’s plants and animals. In Australia, more than 1,700 species and ecological communities are known to be threatened and at risk of extinction. There are many causes for this loss of biodiversity in Australia that are shared worldwide as well. Those causes include: habitat loss, degradation, fragmentation, invasive species, unsustainable use and management of natural resources, changes to aquatic environment and water flows, changing fire regimes, and climate change. Due to these, Australia has experienced the largest documented decline in biodiversity of any continent over the past 200 years. Therefore, many animal and plant species have become extinct or are threatened to become extinct if Australia continues to use the environment in the same way. Approximately, more than 50 species of Australian animals have been listed as extinct, including 27 mammal species, 23 bird species, and 4 frog species with 426 animal species (including presumed extinctions) and 1,339 plant species listed as threatened under the EPBC (Environmental Protection and Biodiversity Conservation) Act. Constituting more than a third of Australia's 85 bioregions to have at least 30% of their ecosystems threatened. However, Australia's environment isn't as affected by the causes for the loss of biodiversity as Asia's environment is. Asia covers 14% of the world but contains half of the world's population, with population density eight times higher than the global average and uses about 40% of the total land primary production. Deforestation is the largest influence to Asia's loss of biodiversity but mining, dams, as well as oil and gas development open lands up to further degradation or clearance for
