Since the mid-20th century, humanity has witnessed an unprecedented transformation in how we inhabit and use the planet. This phenomenon, known as the "Great Acceleration", marked the beginning of the Anthropocene, an era where humans became the primary force shaping the Earth.

Between 1950 and 2010, the global population tripled, the world’s GDP grew sevenfold, and the consumption of resources like freshwater, energy, and fertilizers soared exponentially. At the same time, events such as greenhouse gas accumulation, ocean acidification, and biodiversity loss have reached critical levels, threatening ecological balance.

Will Steffen, one of the leading researchers on these dynamics, emphasized that “In a single lifetime, humanity has become a planetary-scale geological force.” This transition not only highlights our biological and geological influence but also assigns us a unique responsibility for the planet’s future.

The use of fossil fuels, intensive agriculture, and industrial development has improved quality of life for millions, but it has come at an enormous environmental cost. In 2020, the total mass of human-made objects (buildings, infrastructure, and manufactured goods) surpassed, for the first time, the mass of natural biomass (animals, plants, and soil). This striking figure underscores humanity’s colossal impact on global ecosystems.The degradation of the biosphere is undeniable: half of the world’s animal species are at risk of extinction, a direct result of habitat destruction and the overexploitation of resources.

The choices made in the coming decades will shape the planet’s destiny. Continuing with the current model leads to a high-risk zone for Earth’s systems. Alternatively, a global commitment to reducing emissions, adopting regenerative economic models, and protecting biodiversity could spark a "great reversal," restoring the planet to a safe operating space.

Every action, whether individual or collective, serves as a lever for change. Investing in biodiversity, promoting sustainable technological solutions, and embracing more responsible daily practices are not just necessary—they are achievable.

Now is the time to act with responsibility and vision, to rethink our impact and build more resilient systems. The choice is ours, and the time to decide is now.
