11 Threats to the Environment

12 Climate Change What is climate change? What is climate change? “long-term changes in climate, including average temperature and rainfall” (www.climatechange.gov.au/climate-change.aspx) Since the beginning of the 20 th Century, Australia has an increase of 0.8 degrees C in average temperatures Since the beginning of the 20 th Century, Australia has an increase of 0.8 degrees C in average temperatures The Kyoto Protocol The Kyoto Protocol Australia's carbon dioxide emissions per capita are among the highest in the world Australia's carbon dioxide emissions per capita are among the highest in the world

13 Land Clearing Farming Farming Agriculture Agriculture The major use of land in Australia – 60% or 454 million hectares The major use of land in Australia – 60% or 454 million hectares Livestock (cattle and sheep) Livestock (cattle and sheep) Mining Mining 0.02% of the land 0.02% of the land Logging Logging Urbanisation Urbanisation Over 80% of Australians live in urban centres within 50km of the coast and these areas make up only about 1% of the total land mass of Australia. Over 80% of Australians live in urban centres within 50km of the coast and these areas make up only about 1% of the total land mass of Australia.

14 Drought Water use Water use ¾ water used by agricultural and pastoral sectors (Markus 2009:21) ¾ water used by agricultural and pastoral sectors (Markus 2009:21) The world’s driest continent The world’s driest continent 2/3rds of the country is arid or semi-arid and only partly habitable due to the lack of permanent water 2/3rds of the country is arid or semi-arid and only partly habitable due to the lack of permanent water Climate and annual rainfall are highly variable Climate and annual rainfall are highly variable Only 6% of Australia’s land is classed as arable Only 6% of Australia’s land is classed as arable

15 Population Currently 22.7 million Currently 22.7 million Expect 30 million by 2050 (Markus 2009:18) Expect 30 million by 2050 (Markus 2009:18) Urbanisation (high density in coastal cities) Urbanisation (high density in coastal cities)

16 Consequences Pollution Pollution Soil Salinity Soil Salinity 17 million hectares in Australia will be at risk of serious dryland salinity problems by 2050 (National Land and Resources Audit) 17 million hectares in Australia will be at risk of serious dryland salinity problems by 2050 (National Land and Resources Audit) Loss of Biodiversity and Loss of Habitat Loss of Biodiversity and Loss of Habitat Species Extinction Species Extinction Since European arrival 220 years ago: Since European arrival 220 years ago: 104 plant and animal species = extinct. 104 plant and animal species = extinct. 88 = currently critically endangered 88 = currently critically endangered 1502 = endangered, vulnerable or conservation dependent (Markus 2009:27) = endangered, vulnerable or conservation dependent (Markus 2009:27).
