Earth's Safe Operating Space for Humanity Exceeded, Scientists Warn

A new study warns that human activity has crossed six out of nine planetary "boundaries" crucial for maintaining Earth's stability and livability. These boundaries include biosphere integrity, climate change, freshwater changes, ocean acidification, stratospheric ozone depletion, atmospheric aerosol loading, land system change, introduction of novel entities, and biogeochemical flows. The study emphasizes the need to reduce pressure on these boundaries to prevent irreversible changes and harm to the planet. The researchers stress that focusing solely on climate change is not enough; the biodiversity crisis must also be addressed to ensure a sustainable future.
