What % of the population lives within 100Km of the coast?

What are recreational vehicles?
the development and physical growth of towns and cities, including residential areas, as people move to these locations
What is Urbanisation?
The impacts of technology on the environment are caused by the production or disposal of the technology itself.
What is Indirect Impact
• tourism
• fee-for-service recreational activities
• forestry
• farming and agriculture
• the production of energy
• mining
• game hunting
• development and urbanisation.
What are Economic activies?
• conservation covenants
• following minimal impact guidelines and codes of conduct
• revegetation, rehabilitation and restoration programs
• implementing a whole-farm plan, such as regenerative farming
• disposing of waste appropriately, such as using recycling and green waste bins
What are community-based environmental actions?
increased motor vehicle exhaust emissions, which can lead to further pollution of the environment over a period of time• more land development and urbanisation, as more people are potentially attracted to the area due to increased access.
What are the Indirect Impacts of Transport?
natural or semi-natural systems (e.g. parks, wetlands, green roofs, trees or rain gardens) designed to provide ecosystem services and benefits to urban communities
What is green infrastructure?
introduction of weed species
• fire scars, depletion of firewood and damage to vegetation due to campfires
• soil compaction and erosion due to repeated treading and tent pitching, and walking on fragile soil types compared to rocky ground
• pollution from inappropriate toileting and rubbish-disposal methods
• wildlife dependency on humans due to feeding fauna
• disruption of wildlife due to domestic animals and increased noise levels
• decreased biodiversity levels due to habitat loss
What are negative impacts due to recreational activites?
the preservation, protection, management or restoration of the natural environment, inclusive of ecosystems, vegetation, wildlife and natural resources, such as soil and water
What is conservation?
Australian Wildlife Conservancy
Bush Heritage Australia
Nature Conservancy
Tasmanian Land Conservancy
Trust for Nature
What are examples of CONSERVATION ORGANISATIONS?
air quality, greenhouse gas emission, ozone depletion, water quality, use of natural resources and production of noise.
What are the impacts of technology manufacturing?
the rapid expansion of the geographic extent of cities and towns, often characterised by low-density residential housing and increased reliance on private vehicles for transportation
What is Urban Sprawl?
The Australian government’s central environmental polic
What is the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act)
Positive impacts as a result of conservation activities include:
preservation of sensitive vegetation
protection of areas
reduction in areas of erosion,
smaller and more centralised impacts from human waste
rehabilitation and revegetation
disease control
a reduction in human waste,
reintroduction of species
What are positive impacts of Conservation?
a system of farming principles and practices that seeks to rehabilitate and enhance the entire ecosystem of the farm by placing a heavy premium on soil health, with attention also paid to water management, fertiliser use, carbon sequestration and more
What is regenerative farming?
•contributing to atmospheric pollution
• reducing the need to burn timber.
What are the direct impacts of Fuel stoves
Loss of habitat
• Increased pollution
• Increased surface temperature
• Increased energy consumption
• Water management
