Two reports worth noting and posting:
Romy Zyngier: Australia has overshot three planetary boundaries based on how we use land (The Conversation, 6 June 2022) notes that: For the first time, we have taken the planetary boundaries framework – which can be hard to visualise on a global scale – and applied it 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.
And Warren Cornwall: How much land is needed to stop the biodiversity crisis? (Anthropocene, 8 June 2022) reports that: Environmentalists have been lobbying world leaders to commit to protecting 30% of Earth’s land for biodiversity at an international conference scheduled for later this year. That number, daunting as it seems, might not be high enough. Nearly half of the planet’s lands would need some kind of conservation to help ensure the survival of roughly 35,000 animal species, according to new research, including land occupied by around a quarter of all people.
