"We used to believe the world’s resources were almost limitless. But as we
spread out across the planet, we consumed more and more of these resources. For
decades, scientists have warned we are approaching the limits of what the
environment can tolerate.
In 2009, the influential Stockholm Resilience Centre first published its
planetary boundaries framework. The idea is simple: outline the global
environmental limits within which humanity could develop and thrive. This
concept has become popular as a way to grasp our impact on nature.
For the first time, we have taken these boundaries – which can be hard to
visualise on a global scale – and applied them to Australia. We found Australia
has already overshot three of these: biodiversity, land-system change and
nitrogen and phosphorus flows. We’re also approaching the boundaries for
freshwater use and climate change.
The nation’s land use is a key contributor to these trends, with natural
systems under increasing pressure as a result of many land management
practices. Luckily, we already know many of the solutions for living within our
limits, such as waste management, conservation and restoration of natural lands
in conjunction with agriculture, and shifts in food production."
