More than 80 per cent of Australians live within kilometres of the coast. Human activity continues to exert pressure on marine environments.
Research is continuing into the underlying cause.

Groundwater is vulnerable to climate change and climate variability. Potential climate risks for groundwater include reduced groundwater recharge and supplies, seawater intrusion to coastal aquifers, reduction of freshwater availability on small islands, and increased demand from communities and industries. Supply from surface and groundwater is not the only risk to our water resources. For example, increased extreme weather events, such as bushfires and floods, can affect water quality and water infrastructure.
Increasing temperatures may increase the risk of bacterial contamination in water supplies, blue-green algal outbreaks and acid-sulphate soil issues. Inthe Government released the NWI module: Considering climate change and extreme events in water planning and managementa supporting document to the National Water Initiative Policy Guidelines for Water Planning and Management. The module provides guidance to jurisdictions on how to consider and incorporate possible impacts from climate change and extreme events in water planning and management.

It provides a suite of options for managing climate risks, allowing water planners to develop an approach tailored to their local circumstances such as the type of water resource, and level of demand for water. Natural ecosystems The State of the Environment report found climate change is one of the main pressures on the Australian environment and exacerbates other pressures including land-use change, habitat fragmentation and degradation, and invasive species.
Climate change, particularly rising temperatures, increases the impact of these existing pressures, undermining the resilience of native species. Scientists expect climate change to cause changes to the abundance and geographic range of many species, restrict or alter species movement and interfere with their lifecycles such as the timing of germination.
Ecosystems have a limited capacity to manage these multiple pressures compared to human systems. Rates of climate change, together with other pressures, limit the capacity of species to adapt in situ or migrate to more climatically suitable areas, where such areas exist.
More information Health and wellbeing Human health is linked with environmental factors such as temperature, and air and water quality. The increasing incidence of heatwaves is leading to a greater risk of injury, disease and death. Heatwaves have caused more loss of life than any other natural hazard in Australia over the past years. The increasing frequency and intensity of other extreme weather events poses risks to human health, including injuries, disease and death, and disruption to health services.
Drought has been linked to decreased mental health, particularly in rural communities. The impact of the January heatwave on health and wellbeing in Victoria The duration, frequency and intensity of extreme heat events have increased across large parts of Australia. Temperatures are projected to continue increasing with more extremely hot days and fewer extremely cool days.
Those most at risk during heatwaves include the elderly, children, outdoor workers, Indigenous Australians and those already suffering from chronic disease. The January heatwave resulted in more deaths than normally expected at that time of year in Victoria. More information Disaster risk management The costs of extreme weather events range from environmental impacts and financial costs incurred by governments, businesses and households to impacts on the physical and psychological health of individuals.
Consequently, in Australia was the eighth highest emitter of CO2 gases per capita in the world liberating Most of Australia's demand for electricity depends upon coal-fired thermal generation,  owing to the plentiful indigenous coal supply, limited potential electric generation and political unwillingness to exploit indigenous uranium resources although Australia accounted for the world's second highest production of uranium in [ citation needed ] to fuel a 'carbon neutral' domestic nuclear energy program.
Conservation in Australia 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.
Climate change impact on Australia may be irreversible, five-yearly report says
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.
