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 - more than half the world’s tropical forests have been destroyed since the 1960s[3].
- Ocean acidification - more CO2 in the atmosphere means more acidity in the oceans.
- Ozone depletion
- Microplastics via overconsumption.
- the nitrogen cycle
- the phosphorus cycle
These issues combined are accelerating us towards collapse.
