Week 4 Spark: Water scarcity on a water world?!
Hi Everyone!
This week we take a close look at water, its importance, it use, and its abuse! To get discussion rolling please consider a brief (2+ paragraph) response to one of the following Spark prompts.
If you notice that a particular question has been well addressed please move to a different question… otherwise this component of discussion can become stale and less useful in preparing you for the exams.
Also please enter a descriptive phrase in the subject line of your post so that people will know which spark prompt you are addressing. Thanks for understanding!
