Researchers warn that humanity has crossed almost every frontier that made our planet safe and fair.
In a new study, an international team of forty scientists focused on determining the limits of the planet’s life support systems. The results were underwhelming—humanity had crossed nearly all permitted Earth System Boundaries (ESB), which made life on the planet safe, he wrote. daily Mail.
Researchers have found that social and economic systems based on unsustainable resource extraction and consumption lead to rapid changes that undermine these systems, and push the Earth toward inevitable destabilization.

During the study, scientists analyzed the climate, the planet’s biodiversity, fresh water and various types of soil, water and air pollution. The team has identified safe and just boundaries that govern the planet, protect other species, minimize significant harm to humans, and support overall human development.
The results indicate that the maximum permissible limit was not violated in only one category – aerosol pollutants. Scientists note that climate change today has crossed the 1°C threshold, but the safe line of 1.5°C above the pre-industrial average global temperature remains intact.
According to the study’s lead author, Professor Johan Rockström of the Potsdam Institute for Climate Impact Research, the team’s findings are very worrying as significant “social impacts” are already being felt. The researcher also pointed out that in the five domains analyzed, many boundaries have already been violated at the global and local levels.
Simply put, if the transition does not occur in time, the most likely scenario is tipping points and widespread impacts on human well-being. Researchers note that it is extremely important for humanity to prevent such a development of events if we really want a secure future for ourselves and future generations.
In 2015, United Nations member states agreed to unite to limit global temperature rise to 1.5°C and protect biodiversity in 30% of land, sea and freshwater. Researchers have now come to the conclusion that we are a long way from these goals — in fact, humanity is not even on track to achieve them.
Earth Commission researchers believe we won’t be able to get any closer to these goals without a global shift. Moreover, these shifts must be of a systemic nature and be related to the economic, technological and political factors of land degradation.
According to study co-author Professor Joyet Gupta from the University of Amsterdam, fairness is key to survival and to avoid crossing all acceptable boundaries. At least that’s the conclusion the team reached, and the researchers now note: “This is not a political choice, but something necessary to achieve planetary stability.” This is evidenced by a series of environmental assessments.
