<u>Answer</u>: Sustainable development
<u>Explanation</u> :
The concept of sustainable development is based on the ideas of sustainable forest management and is derived from the Brundtland Report (1987).

Lakes, rivers, water vapor, and ice sheets are all examples of sources of freshwater. I hope your sister gets a good grade!
