Lecture by Dr Katherine Richardson at the Molecular Frontiers Symposium "On Human Origins and the Future of Humanity", at Lund University April 18-19, 2024. The symposium was co-organized with Lund University and the Royal Physiographic Society of Lund.
ABSTRACT:
The climate and biodiversity witness that our societies cannot continue to flourish unless we actively manage our relationship with the Earth and its resources. Such management requires guardrails to identify how much perturbation of critical Earth system processes is “too much”. The planetary boundaries framework, first introduced in 2009, and since twice updated, identifies science-based limits for human perturbation of Earth system processes. The most recent update shows that 6 of 9 boundaries are transgressed and that transgression is increasing. It also shows, however, that human perturbation of the ozone layer - a boundary transgressed or nearly transgressed in the 1900s - is now in back within a “safe operating space”. The framework and how it can be used for management of the Human-Earth relationship are presented here.
