The total global population is about . billion.
What percentage of the worlds population does
not have access to a reliable source of fresh, clean
water? What will be an ideal response?
Question 2Compare the information in Table to the predictions you made about
global water reservoirs in Table in Warm-up .. Which reservoirs did you
overestimate and which did you underestimate? What will be an ideal response?
Question 3Using the data in Table , calculate what percentage of the worlds potable
water (freshwater that is fit to drink) is directly accessible in surface
reservoirs such as freshwater lakes and rivers. What will be an ideal response?
