Middle age growth is decreasing, leaving a growing youth age group. There could be potential problems between the elderly and the youth. Water is essential. No one can survive without it. For millions of the world's poorest people fetching water for their daily needs means a long walk, often to a polluted source.
Poor sanitation makes a bad situation worse.
The cost is an untold amount of preventable illnesses and millions of premature deaths. 10 million children will die unnecessarily this year from illnesses which can be averted by basic improvements to the water supplies and sanitation. More than 2 million children died as a result of armed conflicts in the past decade, in part because of landmines. Some landmines have been designed as small, bright, and colorful butterfly looking plastic toys. They are very cheap and can be spread over large areas by aircraft.
