We submit that the safe operating space of the planetary boundary of novel entities is exceeded since annual production and releases are increasing at a pace that outstrips the global capacity for assessment and monitoring. The novel entities boundary in the planetary boundaries framework refers to entities that are novel in a geological sense and that could have large-scale impacts that threaten the integrity of Earth system processes. We review the scientific literature relevant to quantifying the boundary for novel entities and highlight plastic pollution as a particular aspect of high concern. An impact pathway from production of novel entities to impacts on Earth system processes is presented.

There has been a 50-fold increase in the production of chemicals since 1950. This is projected to triple again by 2050

Humans have amazing strengths, but also significant weaknesses. Chief among them, perhaps, is our collective difficulty in grasping the mathematical consequences of exponential growth. Alternative energy technologies have trouble preserving expectations. Human psychology and political/economic institutions turn a technically difficult predicament into a nearly hopeless trap. We are lamentably ill-equipped to appreciate the abnormality of our time and assess a more accurate picture of what long-term “normal” must look like.
