参考答案: B
本题详细解析:
Natural capital refers to:i 7oa+nh zainni f6)h-f)- je resources found in nature that we can use for goods and services, preferably in a sustainable way. It does not need to increase to be sustainable, however, it just needs to)o6iz-e7ffnn)j+:ai han- h i stay at the same level to produce those goods and services forever.
Options A, C and D combine neatly to form a definition of sustainability: Managing and using resources for human populations so that nature replenishes all the resources that humans have used and that ecosystems become healthy again after the resources have been extracted. This would mean that we could keep using those resources forever as they are not used up.
