More than a century after Rosa Luxemburg posed the alternative “socialism or barbarism?”, the new reality of extractivist capitalism is pushing humanity to the edge of the abyss with a new equation: “Ecosocialism or barbarism?”

Seven of the nine planetary boundaries that condition the existence of our species on Earth have been crossed: climate change, biosphere integrity, land-use change, the freshwater cycle, biogeochemical cycles, new chemical pollutants, and a seventh, ocean acidification, which was exceeded in 2025. In just four years, the Earth has officially crossed four of these nine danger thresholds.

"At a time when humanity’s very survival is at risk, we need a movement that once again offers a hopeful alternative to the rise of the far right and the failures of neoliberalism. That is why we call on all those who defend human dignity and strive for an alternative to destructive capitalism to join us in Brussels from 15 to 17 May 2026 for the 7th International Ecosocialist Encounters."
