Derzeit ist Menschheit gerade dabei, aufgrund ihres übermäßigen Ressourcenverbrauchs die Grenzen der Tragfähigkeit des Planeten Erde zu überschreiten. 2009 haben 30 internationale Expertinnen und Experten von den neun Prozessen (eigentlich zehn, aber da der Phosphor- und Stickstoffzyklus miteinander verzahnt sind, zählen sie als ein Prozess), die für die Stabilität des Systems Erde relevant sind, vier identifiziert, die die planetarische Grenzen erreicht – Phosphorzyklus – oder sogar überschritten haben – Verlustrate der biologischen Vielfalt (terrestrisch und marin), Klimawandel und Stickstoffkreislauf (Johan Rockström et al.: A safe operating space for humanity, Nature 461, 24 September 2009)
