Warm-up Quick Quiz: On the scrap of paper, answer the following question…What is the difference between water availability and water sustainability?
Remember???WATER AVAILABILITY– How easy
it is for people to access water in a particular area
The average distance that women in developing countries walk to collect water per day is four miles and the average weight that women carry on their heads is approximately 44 pounds.
Remember???WATER SUSTAINABILITY– The use
of water now that ensures that there will be enough usable water for future generations.
