Public disagreement with this opinion is generally dismissed as expression of vested interests, for example from the coal industry.

Australia is a major exporter and consumer of coal, the combustion of which liberates CO 2. Consequently, in Australia was the eighth highest emitter of CO 2 gases per capita in the world liberating Conservation in Australia is an issue of state and federal policy.

Australia is one of the most biologically diverse countries in the world, with a large portion of species endemic to Australia.

Preserving this wealth of biodiversity is important for future generations. A key conservation issue is the preservation of biodiversity, especially by protecting the remaining rainforests.

The destruction of habitat by human activities, including land clearing, remains the major cause of biodiversity loss in Australia.

The importance of the Australian rainforests to the conservation movement is very high. Australia is the only western country to have large areas of rainforest intact.

Forests provide timber, drugs, and food and should be managed to maximize the possible uses. Currently, there are a number of environmental movements and campaigners advocating for action on saving the environment, one such campaign is the Big Switch.

Land management issues including clearance of native vegetation, reafforestation of once-cleared areas, control of exotic weeds and pests, expansion of dryland salinity, and changed fire regimes.

Intensification of resource use in sectors such as forestry, fisheries, and agriculture are widely reported to contribute to biodiversity loss in Australia.

Coastal and marine environments also have reduced biodiversity from reduced water quality caused by pollution and sediments arising from human settlements and agriculture.

In central New South Wales where there are large plains of grassland, problems have risen from—unusual to say—lack of land clearing. The Daintree Rainforest , a tropical rainforest near Daintree, Queensland covering around square kilometres, is threatened by logging, development, mining and the effects of the high tourist numbers.

There are some government programs in Australia which are the opposite of conservation such as killing wildlife ; an example of this is shark culling , which currently occurs in New South Wales and Queensland.

Over a hundred species of fauna are currently under serious threat of extinction. Australia has a poor record of conservation of native fauna.

The extinction of Australian megafauna is attributed to the arrival of humans and since European settlement, 23 birds, 4 frogs, and 27 mammal species are also known to have become extinct.

One of the notable issues with marine conservation in Australia is the protection of the Great Barrier Reef. The government of Queensland currently kills sharks in the Great Barrier Reef using drum lines , causing damage to the marine ecosystem.

Whaling in Australia took place from colonisation in In Australia terminated whaling and committed to whale protection.

The main varieties hunted were humpback , blue , right and sperm whales. Western Australia culled sharks in , killing dozens of tiger sharks and causing public protest.

From to the present, the government of Queensland has killed sharks on drum lines and shark nets , a process that also kills other animals such as dolphins [23] and dugongs.

New South Wales has a shark net program that kills sharks as well as other marine life. Jessica Morris of Humane Society International calls shark culling a "knee-jerk reaction" and says, "sharks are top order predators that play an important role in the functioning of marine ecosystems.

We need them for healthy oceans. While there have been no oil spill environmental disasters of the scale of the Exxon Valdez in the country, Australia has a large oil industry and there have been several large oil spills [1].

Spills remain a serious threat to the marine environment and Australian coastline. The largest spill to date was the Kirki tanker in which dropped 17, tonnes of oil off the coast of Western Australia.

Premier Anna Bligh described the spill as "worst environmental disaster Queensland has ever seen". A serious issue to the Australian marine environment is the dumping of rubbish from ships.

There have been a number of cases, [28] particularly involving the navy of Australian and other countries polluting Australian waters including the dumping of chemical warfare agents.

Recently documented cases include the aircraft carrier USS Ronald Reagan in which was found to be dumping rubbish off the shores of Moreton Island.

Introduced plants that have caused widespread problems are lantana and the prickly pear bush. The introduction and spread of animals such as the cane toad or rabbit can disrupt the existing balances between populations and develop into environmental problems.

The introduction of cattle into Australia and to a lesser extent the dingo , are other examples of species that have changed the landscape.

In some cases the introduction of new species can lead to plagues and the extinction of endemic species. The introduced species red fox has single-handedly caused the extinction of several species.

Tasmania takes the threat of red fox introduction so seriously that it has a government sponsored taskforce to prevent fox populations from taking hold on the island.

Clearcutting of old growth forests is continuing in parts of Australia. This often involves the destruction of natural ecosystems and the replacement with monoculture plantations.

In the prehistory of Australia the Indigenous Australians used fire-stick farming which was an early form of land clearing which caused long term changes to the ecology.

With European colonisation land clearing continued on a larger scale for agriculture - particularly for cattle, cotton and wheat production.

Illegal fishing places further pressure on some species, with patagonian toothfish in the Southern Ocean and shark for fins in northern Australian waters being the worst affected.

Introduction of exotic species It is estimated that Australia gains around 20 new pests or diseases each year. Some well-known examples include cane toads, rabbits, willows and, more recently, black striped mussels and red fire ants.

Historically, feral cats, foxes and rabbits have been a cause of local extinctions and significant reductions in range for native species through a combination of habitat modification and predation.

They are a major ongoing problem. Weeds are an equally significant pressure on ecosystems, with more than 2, species of introduced plants now thriving in the wild in Australia.

They have invaded every part of the landscape - bushland, rangelands, coasts, rainforests, deserts and farms.

Ballast water from shipping has been responsible for introducing more than species, and possibly as many as species, into Australian waters. Modelling predictions estimate that each year almost 19, tonnes of phosphorus and , tonnes of nitrogen are discharged to rivers flowing to the coast.

Stubby Cooler sind eine der besten australischen Erfindungen.

With European colonisation land clearing continued on a larger scale for agriculture - particularly for cattle, cotton and wheat production. The extinction of 20 different mammals, 9 bird and 97 plant species have been partially attributed to land clearing.

The consequences of land clearing include dryland salinity and soil erosion. These are a major concern to the landcare movement in Australia.

The clearing of native vegetation is controlled by Federal laws indirectly , State law and local planning instruments. The precise details of regulation of vegetation clearing differ according to the location where clearing is proposed.

The protection of waterways in Australia is a major concern for various reasons including habitat and biodiversity, but also due to use of the waterways by humans.

The Murray-Darling Basin is under threat due to irrigation in Australia , causing high levels of salinity which affect agriculture and biodiversity in New South Wales , Victoria and South Australia.

These rivers are also affected by pesticide run-off and drought. Rivers and creeks in urban areas also face environmental issues , particularly pollution.

Water use is a major sustainability issue in Australia. Australia is one of the most urbanised countries in the world.

Many Australian cities have large urban footprints and are characterised by an unsustainable low density urban sprawl. This places demand on infrastructure and services which contributes to the problems of land clearing, pollution, transport related emissions, energy consumption, invasive species, automobile dependency and urban heat islands.

The urban sprawl continues to increase at a rapid rate in most Australian cities, particularly the state capital cities, all of which with the exception of Hobart are metropoleis.

In some centres, such as Sydney and Greater Western Sydney , [47] Greater Melbourne [48] and South East Queensland [49] large metropolitan conurbations threaten to extend for hundreds of kilometres and based on current population growth rates are expected to become megacities in the 21st century.

Most Australian cities population growth is a result of migration in contrast to the Birth rate and fertility rate in Australia , which is contributing to the ongoing trend of urbanisation.

In recent years, some cities have implemented transit-oriented development strategies to curb the urban sprawl. There are also population decentralisation programs at state and federal levels aimed at shifting populations out of the major centres and stemming the drivers to rapid urbanisation.

The Victorian government has run a decentralisation program since the s, having had a ministerial position appointed and ongoing promotional and investment programs for stimulating growth in Regional Victoria.

However policy has swung over the decades, primarily due to local development priorities and agendas and a lack of federal co-ordination to the problem.

Australia does not have restrictions on the dumping of toxic materials that are common in other countries, such as dumping Cathode Ray Tubes which leach heavy metals into water catchments.

Due to the lack of sufficient sites for toxic waste disposal large quantities of toxic waste are trucked between states to remote dumping grounds or exported overseas in ships.

Australia has the largest reserves of uranium in the world and there has been a number of enquiries on uranium mining. The anti-nuclear movement in Australia is actively opposing mining as well as preventing the construction of nuclear power plants.

At least leaks, spills and licence breaches have occurred at the Ranger uranium mine between and The following is a list of controversial development projects due to concerns of environmental effects.

FAO Forestry Paper A number of marine pests have arrived in Australia in the ballast water of cargo ships.

Marine pests include the black-striped mussel Mytilopsis sallei , the Asian mussel , the New Zealand green-lipped mussel , and the European shore crab.

The Northern Pacific seastar in Tasmania , Inverloch , and Port Phillip has caused much localised environmental damage.

Weeds invade natural landscapes, waterways, and agricultural land. Originally, plants were most likely to be considered weeds if they had a direct economic impact, especially on agricultural production.

However, growing environmental consciousness since the s has led to the recognition of environmental weeds; plants which have adverse effects on the natural ecosystem of an area.

The management of invasive species is carried out by individuals, conservation groups, and government agencies. The Australian Quarantine and Inspection Service is responsible for ensuring that no new species with the potential to become invasive species enter Australia.

Several scientific bodies are involved in research for the control of invasive species. The CSIRO has released several successful biological pest control agents and developed chemical agents for pest and weed control.

Rabbit haemorrhagic disease escaped containment from an Australian Government research facility and spread across Australia. Rabbit hemorrhagic disease was subsequently legalised for the control of wild rabbits.

The moth Cactoblastis cactorum was introduced for the control of prickly pear, and the salvinia weevil Cyrtobagous salviniae for the control of aquatic weed Salvinia.

More doubtful biological controls were the cane toad , which was introduced to control the sugar cane destroying cane beetle; instead the cane toad ate anything and everything else—the beetle was not its preferred food source given choice.

The cane toad in Australia has become the biological control that is most infamous for having been a complete failure as well as becoming an environmental nightmare.

Walter Froggatt , and economic entomologist, warned of this likelihood at the time. Another example of a poorly researched introduced biological control is the sap sucking lantana bug Aconophora compressa also from South America that was introduced into Australia in the to eat the lantana.

Unfortunately, the lantana bug also attacks other trees including fiddlewood trees which has caused distress to some gardeners.

The lantana bug had been tested for six years on 62 different plants. Aconophora compressa was the 28th insect introduced to control lantana in about 80 years.

These flies, along with other species of fly and parasitic worm, use the dung as a breeding and feeding ground. Cooperative Research Centres for weed management and pest animal control, have been established by the federal government.

They coordinate research and funding between a number of university and government labs for research into control of invasive species. Non government organisations have also been established to fight invasive species, for example, the Invasive Species Council ISC.

Volunteer groups, such as SPRATS , have also made very significant contributions to fighting invasive species, in their case removing sea spurge from large areas of Tasmanian coastline.

Australian quarantine regulations such as those limiting banana imports from developing economies have been recognised as protectionist trade barriers by economists including Kevin Fox, head of Economics at the Australian School of Business.

The weakening of restrictions on importing raw produce into Australia mandated by the World Trade Organisation Future may pose risks of introducing exotic disease organisms.
