It has been reported that about 2.2 billion people in the world do not have access to safe water, and about 4.2 billion people also do not, to safely managed toilets. There still are many countries in the world that do not have infrastructure facilities and systems. For example, many people use untreated waste water from home and factories as drinking water in developing countries. Such untreated water has a negative impact on the health for children. And there are many cases of ill-equipped toilets set in the outside without privacy and electricity. It causes the dangerous situation for women and children to be subjected to violence.
What can we do now for that? For example, to stop using the water while you are lathering up the soap would be the first important step we can take, to conserve water on a daily life. A small care of action for the people in addition to myself could be a power to save the world.
