Abstract

The planetary boundaries framework is a fundamental model designed to identify safe environmental limits for human activities. This framework was first introduced in 2009 by Johan Rockström and his colleagues, identifying nine critical boundaries necessary for maintaining the stability of the Earth and its environment. By September 2023, significant updates to this framework have shown that six out of the nine boundaries are currently at risk and require urgent global action. This research examines the historical development and current status of this framework, including an analysis of the impacts of human activities on planetary boundaries. Reports indicate that climate changes, loss of biodiversity, and unsustainable use of freshwater resources are among the most pressing challenges threatening these boundaries. The focus on integrated governance and understanding the interconnectedness among these boundaries is presented as vital necessities for sustainability and planetary health. Ultimately, this research emphasizes the need for immediate action and offers new suggestions for operational strategies to return to safe ecological conditions.
