Which category does not make good use of the remaining 10% of usable land?

The choice of industrial waste sites for the category that does not make good use of the remaining 10% of usable land is valid for several reasons. Quality land management aims to prioritize land use that is sustainable, beneficial to the community, and conducive to healthy environments.

Industrial waste sites typically involve contaminating processes and materials that can have detrimental effects on both the land and surrounding ecosystems. They require substantial areas to manage waste safely, which can lead to further land degradation and limit other productive uses for the land. This contrasts with agriculture, housing, and commercial development, which generally provide essential services and contribute positively to the economy and community welfare by utilizing land for food production, living spaces, and business operations respectively.

In summary, industrial waste sites do not align with the principles of effective land use that maximize the potential of usable land while minimizing environmental impact. This makes it clear why they are not considered a good use of the remaining usable land compared to the other options.
