Sustainable Population Australia
Sustainable Population Australia (SPA) (formerly Australians for an Ecologically Sustainable Population) is an Australian special advocacy group, founded in Canberra in 1988, that seeks to establish an "ecologically sustainable" human population. SPA claims that it is an "ecological group dedicated to preserving species' habitats globally and in Australia from the degradation caused by human population growth", and that it "works on many fronts to encourage informed public debate about how Australia and the world can achieve an ecologically sustainable population".
SPA argues that population growth exacerbates Australia's water shortage and adds to greenhouse gas emissions.
SPA also seeks to highlight what it claims are the negative economic effects of population growth, such as increased housing costs, lower wages and living standards, and opposes the current historically high level of immigration to Australia.
