Stratospheric ozone depletion
The stratospheric ozone layer in the atmosphere filters out ultraviolet radiation from the sun. A depletion of the ozone could increase the cases of skin cancer in humans, and both terrestrial and marine systems may be harmed. So far, this is the one boundary where humanity managed to solve the matter after exceeding its tipping point.
Atmospheric aerosol loading
Human activity increases the aerosol loading by releasing pollutants into the atmosphere. The World Health Organization estimates that due to this aerosol pollution, over 4 million people die on a yearly basis. In highly polluted areas, changes in climate systems have already been observed.
During the academic year 2022-2023, the New Energy Academy will elaborate on the nine planetary boundaries. Inspired by the documentary ‘Breaking Boundaries’ from Sir David Attenborough and Johan Rockström, the New Energy Academy brings you more insights about sustainability and shows you what is needed to become a sustainable and nature-inclusive society. You can find the documentary on Netflix.
