The issue of debating the change of public space usage, such as demolishing a skating park for an arboretum, fundamentally involves allocating scarce resources. In economics, the term "scarcity" refers to the limited availability of resources that are in demand. Public spaces are finite, and the decision to repurpose these spaces for different uses reflects the need to allocate them in a way that serves the interests and needs of the community.

When considering transforming a skating park into an arboretum, policymakers and stakeholders must weigh the benefits of each option, evaluate how public interests align with the proposed changes, and consider the long-term implications of that allocation. This encompasses understanding the opportunity costs involved, as choosing one resource use (the arboretum) means forgoing the benefits that another use (the skating park) would provide.

The other choices do not accurately capture this scenario. Eliminating scarce resources would imply removing them entirely, which doesn't apply here. Maximizing resources typically suggests increasing production or efficiency rather than making choices about usage. Locating scarce resources focuses more on finding their presence rather than deciding how to best utilize them, which is the crux of the problem stated.
