This table shows how fresh water is distributed across Earth's surface. How does the table help identify the importance of water conservation?

• It shows that we need to increase the other sources of fresh water.

• It shows that the most important task is conserving surface water.

• It shows that most fresh water is not easily available for use.

• It shows that ice caps and glaciers help to conserve water.
