The concept of 'environmental carrying capacity' has long been central to ecological studies, yet its application to human societies remains contentious. Traditional models assume a linear relationship between population size and resource depletion, but recent research suggests that technological innovation and social adaptation can temporarily raise this threshold. However, such adjustments often lead to a 'rebound effect,' where increased efficiency encourages greater consumption, ultimately accelerating resource exhaustion. This paradox highlights the limitations of purely quantitative approaches in predicting sustainability. Instead, scholars argue for a qualitative framework that incorporates cultural values, institutional flexibility, and ethical considerations. Without such interdisciplinary integration, policy measures based solely on carrying capacity estimates may inadvertently exacerbate the very crises they aim to prevent.
❓ According to the passage, what is the main criticism of traditional carrying capacity models?
A. A. They ignore the role of technological innovation in increasing resource efficiency.
B. B. They fail to account for the potential of social adaptation to permanently solve resource scarcity.
C. C. They rely on quantitative methods that cannot capture the complex dynamics between efficiency and consumption.
D. D. They overestimate the impact of cultural values on environmental sustainability.
✅ 正确答案
C. They rely on quantitative methods that cannot capture the complex dynamics between efficiency and consumption.
