How does Australia population growth affect the environment?

Thus, population growth means that ways must be found to reduce individual footprints.

How does population growth affect the environment?

Populations and Environmental Issues More people require more resources, which means that as the population increases, the Earth’s resources deplete more rapidly. The result of this depletion is deforestation and loss of biodiversity as humans strip the Earth of resources to accommodate rising population numbers.

Air pollution has drastically increased with the large amount of motor vehicles in use due to a rising population. Solid waste disposables from such a large population puts environmental strain on cities.

How does Australia’s geographical distribution affect the environment?

The geographical distribution of Australia’s population creates distinct regional pressures on the environment. Most of Australia’s population is in the east, south-east and south-west. A large proportion of the population is concentrated in urban areas, notably the capital cities.

How will Australia’s ageing population affect the environment?

Our ageing population will progressively affect the type and number of demands placed on environmental resources ( Di Nunzio 2014, ABS 2015a ).
