Planetary Boundaries

We are rapidly heading towards crisis:

Global temperatures - since records began in 1880, nineteen of the twenty hottest years have occured since 2000^[1].
Biodiversity loss - there has been a 68% average decline in the population sizes of mammals, birds, amphibians, reptiles, and fish between 1970 and 2016^[2].
Deforestation via over farming and agriculture.
Ocean acidification
Ozone depletion
Microplastics via overconsumption.
the nitrogen cycle
the phosphorus cycle

These issues combined are accelerating us towards collapse.
