Educational audiobook for children that talks about the sixth of the Sustainable Development Goals (SDGs), clean water and sanitation. Water is a very important resource that all living beings depend on. Water sanitation refers to the set of technical and social actions that make safe and accessible water available to everyone in the world. According to data from the United Nations, one out of every three people in the world does not have access to drinking water, and two out of every five do not have a basic facility to wash their hands. Millions of people do not even have access to a toilet. All this makes hygiene conditions in many places quite limited. For these and other reasons, the UN has made clean water and sanitation one of its Sustainable Development Goals. The United Nations aims to achieve universal access to safe drinking water within the next few years. To achieve this, it is essential to reduce pollution and to make water sources more available in every inhabited place on the planet.
