Statement I: Food, firewood, fibre, and medicinal importance are narrowly utilitarian arguments, as they represent direct, quantifiable economic benefits derived from nature. Therefore, stating they are "broadly utilitarian" is incorrect.

Statement II: Ecosystem services (e.g., pollination, oxygen production) are the broadly utilitarian argument, as they represent indirect, essential benefits that are harder to quantify. Therefore, stating they are "narrowly utilitarian" is incorrect.
