The Australian Environment
 Very large continent: 7.6 million km2
 Diverse environment
 Endemic flora and fauna
 85% flowering plants, 84% mammals, 45% birds, and
89% fish
 Australia has the greatest number of reptiles of any
country:
 755 species
 Driest habitable continent on earth
Australian
Fauna
Monotremes
- egg laying
mammals
Echidna
Threats to the Environment
Climate Change
 What is climate change?
“long-term changes in climate, including average
temperature and rainfall”
(http://www.climatechange.gov.au/climatechange.aspx)
 Since the beginning of the 20th Century, Australia
has an increase of 0.8 degrees C in average
temperatures
 The Kyoto Protocol
 Australia's carbon dioxide emissions per capita are
among the highest in the world
Land Clearing
 Farming
 Agriculture
 The major use of land in Australia – 60% or 454 million hectares
 Livestock (cattle and sheep)
 Mining
 0.02% of the land
 Logging
 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.
Drought
 Water use
 ¾ water used by agricultural and pastoral sectors
(Markus 2009:21)
 The world’s driest continent
 Two thirds 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
 Only 6% of Australia’s land is classed as arable
Population
 Currently 22 million
 Expect 30 million by 2050
 Urbanisation (high density in coastal cities)
Consequences
 Pollution
 Soil Salinity
 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
 Species Extinction
 Since European arrival 220 years ago, 104 plant and
animal species have become extinct. 88 are currently
critically endangered, and 1502 listed as endangered,
vulnerable or conservation dependent (Markus
2009:27).
Exercise
 Form groups based on the topic you have
chosen
 Discuss this topic, in the context of the
Australian Environment, in your group
 You will be asked to present your ideas
back to the class based on,
 Why your topic is the most important,
and
 How it should be protected
Ways of Protecting the
Environment
 Legislation
 Conservation
 E.g., protected areas
 Local and Global Initiatives
 E.g., indigenous knowledge

 What to bring:
 Lunch is provided, but you may wish to
bring snacks.
 We will be outdoors all day. You MUST
