Answer and Explanation:
Insufficient access to water is a disadvantage that many countries have to face. To allow life to continue news in these countries, it is necessary to create strategies that reduce the difficulties due to the lack of water.
Among these strategies, we can mention water rationing (imposing policies that reduce the use and waste to save water quantity), treatment and reuse of wastewater (it can also be used in agriculture and even in consumption, saving millions of liters of water), desalination of sea water (allows sea water to become drinkable).
Although these strategies are not cheap to implement, the cost-benefit of them is very positive.
