state of the planet


Here is a powerful article from Nature to kick-start a decade of science-led world-saving. The diagram reproduced below shows nine planetary systems: climate change; rate of biodiversity loss (terrestrial and marine); interference with the nitrogen and phosphorus cycles; stratospheric ozone depletion; ocean acidification; global freshwater use; change in land use; chemical pollution; and atmospheric aerosol loading. Safe thresholds for each system are indicated by the green ring and the current state of each system is illustrated by the size of the red wedge. As you can see, we have already exceeded the safe thresholds for biodiversity loss, the nitrogen cycle and climate change.

So there you have it: A concise and heavily evidenced review of the state of the planet in one of the most prestigious journals. Everyone should have to read this. Ignorance is a crime.
