Introduction: Source & Availability
3. Introduction to human use of the water cycle: How does our school affect the water cycle?
Think about how our school: the students, teachers and staff use it; the physical campus modifies it. 1. Dams
2. Urbanization 3. Pollution 4. Irrigation 5. Groundwater depletion 6. Deforestation Task: Make a mind map to show how we use water in HK and how we disrupt the water cycle.

6. Case Study
Task 1:
Make a table with 3 columns. Column 1: Identify each of the regions on the map and Column 2: The associated water sources that are in trouble. Column 3: Discuss why they are in trouble. Task 2 Choose 1 example of a water system in crisis! You will present your example to the class. Your presentation must be roughly 1 minute long and contain the following:

7. Water Conflict
Where does water conflict stem from?
We need to consider water as a finite resource. It is renewable but not at the speed we are using it. Not only are we consuming it at an unsustainable rate, but we're also contaminating it at an ever increasing rate. Just like an ecosystem might reach it's carrying capacity and competition for resources might dictate the exsistence of a particular species or organism, humans are having to compete for a basic human right.

8. Map of conflict
Task: Annotate the map to show the conflicts.
Read the information on water conflicts on the BBC site. You will then annotate the world map detailing the key causes and impacts of the water conflict in each of the areas.
Important things to note are: causes and impacts (social, economic, environmental), stakeholders
