A groundbreaking UN report has warned that overconsumption and unsustainable farming are driving intertwined crises in nature and climate, with ecosystems like coral reefs facing extinction within decades. The assessment, prepared over three years and endorsed by nearly 150 governments, underscores the profound relationship between biodiversity loss, global warming, and threats to essential resources like water, food, and health.
Fast-warming oceans, pollution, and overfishing have placed coral reefs—the world’s most endangered ecosystems—on the brink of collapse. Scientists project their potential disappearance within 10 to 50 years, a catastrophic outcome affecting a billion people reliant on reefs for food, storm protection, and tourism.
Economic and environmental trade-offs often remain ignored, with the report estimating annual unaccounted costs from fossil fuels, farming, and fisheries at $25 trillion—equivalent to a quarter of global GDP. Despite nature underpinning over half of the global economy, governments spend $7 trillion annually on harmful subsidies compared to $200 billion on biodiversity conservation.
Unsustainable farming emerges as a key contributor to biodiversity loss, greenhouse gas emissions, and land and water pollution. Overconsumption of red and processed meat has been flagged as a major driver, with one-third of food produced globally wasted while 800 million people go hungry.
The report highlights practical solutions, emphasizing the need for integrated approaches. Community-managed marine areas have boosted local incomes and biodiversity, while sustainable practices like flooding rice fields in California have improved air quality and restored habitats. Addressing these interconnected crises holistically is essential to avoid exacerbating one problem while solving another.
