Scientists Warn Humanity Exceeds Planetary Limits
\n———————————
\nFlinders University researchers warn that human population growth and consumption have pushed Earth beyond its long-term capacity, risking climate, food, and social stability.<\/p>\n
Published in Environmental Research Letters, the study analyzes over 200 years of global population data and ecological trends. Lead author Professor Corey Bradshaw and colleagues, including the late Paul Ehrlich, conclude that current population and resource use exceed sustainable levels, creating mounting environmental pressures.<\/p>\n
The research identifies a \u201cnegative demographic phase\u201d since the 1960s, when population growth rates declined even as total numbers continued rising. Humanity now relies heavily on fossil fuels and overexploited resources to support about 8.3 billion people, whereas the study estimates a truly sustainable global population of roughly 2.5 billion under ecological limits and adequate living standards.<\/p>\n
Population size is strongly linked to rising global temperatures, increasing carbon emissions, and biodiversity loss, often exceeding the environmental impact of per capita consumption. Bradshaw emphasizes that both population growth and patterns of resource use are driving long-term planetary stress.<\/p>\n
The study projects global population could peak between 11.7 and 12.4 billion by the late 2060s or 2070s if trends continue, intensifying food and water insecurity, inequality, and environmental degradation.<\/p>\n
While the report does not predict immediate collapse, it calls for urgent reforms in energy, land, and food management. Smaller populations and lower consumption, the researchers argue, can create better outcomes for humans and ecosystems alike.<\/p>\n","protected":false},"excerpt":{"rendered":"
