The Decline Of Biodiversity In Australia

Biodiversity describes the variety of different types of life found on Earth. It is extent of the variety of organisms present in different ecosystems. This can denote to genetic variation, ecosystem, variation, or species disparity (number of species) inside an area, biome, or planet.

Biodiversity creates an interconnected system where each part builds off of one another to create a functional ecosystem. For example, a small insect such as a bee is critical for survival of many other species because it pollinates so many plants. Currently, the population of bees is dramatically decreasing due to anthropogenic actions such as using harmful pesticides. If the population of bees go extinct, so many species would follow because they would not get pollinated. This is problematic because humans do not have the time or the funds to replicate the vital work of the bee.

So we will talk about biodiversity first. Biodiversity is a group of different living organisms from around the world in one community. And biodiversity helps the biosphere because they can produce better and help other plants and humans in need. Some plants and trees have different characteristics regarding to their species.

Petropoulos et al, (2015) state that ecosystems depend on a balance of each of its biotic factors such as wildlife and abiotic factors to exist and Australian outback ecosystems are no exception. For this reason, amongst others, conservation programs are run which work to protect some vulnerable and many endangered species of wildlife in Australia (Clayton et al,. 2014). Clayton et al, (2014) describe that some conservation programs work on conserving a species’ environment such as protecting surrounding plants and trees from deforestation while others work on illegalising

Australia was once one of the healthiest and wealthiest single megadiverse country in the world. Unfortunately, it is now facing serious environmental problems which will affect the future generations.

Biodiversity is the variety of spices within plants and animals in the environment, it is an indicator of ecosystem health.

The entire Australian marine jurisdictional area, including offshore and sub-Antarctic islands, is considered in this paper. Most records, however, come from the Exclusive Economic Zone (EEZ) around the continent of Australia itself. The counts of species have been obtained from four primary databases (the Australian Faunal Directory, Codes for Australian Aquatic Biota, Online Zoological Collections of Australian Museums, and the Australian node of the Ocean Biogeographic Information System), but even these are an underestimate of described species. In addition, some partially completed databases for particular taxonomic groups, and specialized databases (for introduced and threatened species) have been used. Experts also provided estimates of the number of known species not yet in the major databases. For only some groups could we obtain an (expert opinion) estimate of undiscovered species.

Crikey! What an amazing sight! Known as one of the world’s natural seven wonders “lives” the Great Barrier Reef. Extending like a pulled piece of taffy along the Eastern coastline of Australia, this reef, discerned as the largest biotic structure on the planet. In short, the Great Barrier Reef’s biodiversity has supported thousands of habitats and species, while exuding beauteousness unfathomable by most, bringing millions of tourists annually. Unfortunately, among all of this wonderment lurks destruction and demise by, not only the hands of humans, but pollution, industry, climate change and the ever-mighty grasp of Mother Nature.

To begin, biodiversity is vital in Australia as various plant and animal species depend on each other for survival. This prey and predator cycle helps to maintain the balance of the ecosystem. If multiple sources were suddenly wiped out, there would be serious repercussions. Food webs would be severely affected and various ecosystems would be thrown out of balance.

Biodiversity is the variability of the earth’s species, the genes they contain, the ecosystems in which they live, and the ecosystem processes, such as energy flow and nutrient cycling that sustain all life. (Miller & Spoolman, 2009. pg. 50) It involves many of the levels of organization of life, including genetic diversity species diversity, ecological diversity, and functional diversity. Biodiversity makes up the structure of the ecosystems and habitats that support essential living resources, including wildlife, fisheries and forests. It assists in providing for basic human needs such as food, shelter, and medicine. It composes ecosystems that maintain oxygen in the air, enrich the soil, purify the water, protect against flood and

Loss of Biodiversity will affect the life cycle of several species which depend on each other for survival. This dependence determines the survival of species and the change of our environment. Exploiting the biodiverse species to extinction will result in desertification, rise in carbon dioxide in the atmosphere, increased pollution, increased droughts, increase in loss of items that we derive from nature for our own survival such as honey, fruits, vegetables, medicines etc. The greed to exploit will result in our ultimate extinction If a sustainable solution isn’t provided to prevent loss of biodiversity. If we continue the path we are on without taking steps to balance the equation the planet will

The complexity of life on Earth requires a complex system of interactions to ensure the sustainability of life. The driving force of this system of interactions is biodiversity. McGrath of the National Wildlife Federation provides a clear definition of this concept. Biodiversity is simply the variety in biological systems (McGarth). Although this definition seems to imply variation in organisms, the concept describes something more complex. Biodiversity specifically refers to the variety in three areas of biology: species, genetics, and ecosystems (McGrath). Therefore, biodiversity can be defined as the diversity and interactions that exist in species, genetics, and ecosystems. In this essay, I will illustrate that biodiversity is fundamental to the sustainability of life on Earth as the complex network of biological interactions ultimately benefits individual organisms and I will describe one current threat to biodiversity.

Biodiversity has extreme fundamental value to a healthy life and ecosystem. It is the framework upon which we rely for our needs and well-being. It provides us with food resources, such as fruits and grains, as well as meat, fish, and milk products. Humans are dependent on biodiversity for cultural, economic and environmental stability. For example, farmers rely on bees to pollinate their crops, which allows for a greater supply of food and work. The economic value of biodiversity stems from its production of many everyday essentials such as food supplies, medicine, and raw materials. A healthy ecosystem can provide us with a source of clean water, fresh food, and clean air (Value of Biodiversity). A healthy ecosystem can also withstand disasters and recover sooner. These are

on productivity, it is important to remember that all ecosystems are different. Ecosystems in different biomes could react differently than the way the ecosystem did in this experiment. It would be beneficial if more experiments like this were conducted throughout different types of habitats.

Franck and Brownstone define biological diversity as 'the variety and variability of living organisms and the biological communities in which they live' (36). Decades of progress in both the scientific and political arenas have advanced environmental legislation to protect biodiversity at not only the ecosystem level, but for specific species and genetic material as well. Research has shown the importance of every organism and their role in the global ecosystem, and legislation has gradually matured to protect not only species which may become endangered, but the habitats they need to survive as well. Growing consciousness surrounding environmental issues has enabled these protections to be
