Water-rich vs Water-poor

In the Environmental Management class, we saw a video about how difficult is for some countries to get clean water, after we were asked to write our conclusions:

The video shows how drinkable water is not available in all the world. A poor girl could only get dirty water from a river, while a man just filled his bottle in the tap. Poor people aren’t able to obtain clean water, which is very important to be healthy. This can’t be posible bearing in mind all the resources we have. Is of main importance to stop this, making water available for everyone just as the video shows.
