📖 Reading Passage

The concept of 'environmental carrying capacity' has long been central to ecological theory, yet its application to human societies remains contentious. Unlike wildlife populations, which are constrained by biological limits, human societies can manipulate their environment through technology and trade. However, this capacity for modification does not eliminate resource scarcity; rather, it shifts the burden to global systems. Recent studies suggest that while local carrying capacities can be exceeded through imports, the planet's finite resources impose an ultimate ceiling. Consequently, some scholars argue that sustainable development must reconcile economic growth with ecological boundaries, a challenge complicated by unequal consumption patterns across nations. This perspective implies that technological optimism alone is insufficient, demanding a reassessment of societal values and international cooperation.
