"In 1992, 1,700 scientists warned that human beings and the natural world were
“on a collision course”. Seventeen years later, scientists described planetary
boundaries within which humans and other life could have a “safe space to
operate”. These are environmental thresholds, such as the amount of carbon
dioxide in the atmosphere and changes in land use.
Crossing such boundaries was considered a risk that would cause environmental
changes so profound, they genuinely posed an existential threat to humanity.
This grave reality is what our major research paper, published today,
confronts.
In what may be the most comprehensive evaluation of the environmental state of
play in Australia, we show major and iconic ecosystems are collapsing across
the continent and into Antarctica. These systems sustain life, and evidence of
their demise shows we’re exceeding planetary boundaries."
