The question asks for what Helmut Haberl and colleagues have compiled data on as a measure of how human population growth impacts Earth's natural resources and ecosystem services. The only option that fits this description is C, which refers to human use of Earth's net primary productivity (NPP). NPP is defined as the amount of plant material that's available as food for other organisms in an ecosystem, and humans have been shown to use a significant portion of the NPP globally through activities such as agriculture, forestry, and fishing. This depletion of NPP can have negative impacts on ecosystem services such as carbon storage, nutrient cycling, and water retention, making it a useful measure for assessing human impacts on natural resources and ecosystem services.
