📖 Reading Passage

The concept of ecosystem services has gained significant traction in environmental policy over the past two decades. These services, which include provisioning resources like food and water, regulating processes such as climate and flood control, and cultural benefits like recreation, are often undervalued in economic markets. This undervaluation stems from their public-good nature, leading to overexploitation and degradation. To address this, researchers have proposed payment for ecosystem services (PES) schemes, where beneficiaries compensate providers for maintaining these services. However, critics argue that PES can commodify nature, potentially undermining intrinsic values and leading to unequal power dynamics. A balanced approach, integrating ecological, economic, and social perspectives, is essential for sustainable management.
