Earth's Planetary Boundaries Breached: Humanity's Livability at Risk

A new study published in Science Advances warns that Earth is increasingly becoming uninhabitable for humans as six out of nine planetary boundaries have been breached due to human-caused pollution and destruction of the natural world. These boundaries, which include biosphere integrity, climate change, freshwater changes, land system change, the introduction of novel entities, and biogeochemical flows, determine the fate of the planet. The study indicates that Earth is now well outside the safe operating space for humanity, with failing resilience making it difficult to reach climate goals and bringing the world closer to tipping points.
