📖 Reading Passage

The concept of 'environmental carrying capacity' has long been central to ecological theory, yet its application to human societies remains contentious. Unlike non-human populations, which are typically limited by resource availability and predation, human communities can expand their carrying capacity through technological innovation, trade, and social organization. However, this adaptive capacity is not infinite. Recent studies suggest that even advanced societies face thresholds beyond which further growth leads to systemic breakdown, such as resource depletion or social unrest. The debate hinges on whether technological progress can outpace the escalating demands of a growing population, or whether inherent biophysical limits will eventually constrain human development. This question is not merely academic; it has profound implications for policy-making, particularly in areas of sustainable development and global resource management.
