See the Australian Greenhouse Office web site for more information about greenhouse gas emissions in Australia. The household sector accounts for almost one fifth of Australia's total greenhouse gas emissions. Experts believe that each hectare of regrowth rangelends is estimated to extract 3 tonnes of carbon dioxide per annum. Therefore, it is estimated that each family would need to own 33 hectares of rangelands to naturally extract enough CO 2 from the atmosphere to neutralise their household emissions. Earth Sanctuaries Ltd currently manages over 90,000 hectares of rangelands in Australia facilitating the growth of thousands of trees, shrubs and grasses for wildlife habitat.
Trees naturally extract greenhouse gases from the atmosphere while providing habitat for wildlife.
The Biodiversity Solution Earth Sanctuaries Ltd offers a solution for conserving biodiversity in each habitat region of Australia. Australia's biodiversity is in decline through habitat destruction, introduced species and land degradation. Earth Sanctuaries are managed to maximise and sustain the biodiversity within the safety of a feral-proof fence. The Earth Sanctuaries Biodiversity Solution would require 100 times the amount of investment of the wildlife solution, and therefore be enought to convert the entire Australian landmass into a gigantic Earth Sanctuary. Earth Sanctuaries has a national blueprint for saving wildlife.
