In the framework dedicated to the Days designated by the United Nations to raise more awareness concerning our planet it is to be included the World Toilet Day linked to Sustainable sanitation and climate change. This Day comes on the 19^th of November and it is aimed at raising awareness about the 3.6 billion people living without access to safely managed sanitation.

World Toilet Day and Sustainable Sanitation deserve a particular attention, it is all about taking action to tackle with the global sanitation crisis which is more serious than it seems, and also is about to achieve Sustainable Development Goal 6: water and sanitation for all by 2030. Sustainable sanitation, clean water are essential to help protect and maintain our health security, moreover they contribute to stop the spread of infectious diseases such as for example COVID-19, cholera and typhoid. Sustainable sanitation is a sanitation system which effectively captures and manages (safe disposal) human waste in a safe manner not harming the environment.

To have a sustainable sanitation system can help to fight climate change too. Noteworthy a sustainable sanitation system allows to make productive use of waste, moreover it can also contribute to safely boost agriculture and even reduce emissions. What is more, climate change is accelerating and floods, droughts and rising sea levels are threatening sanitation systems. Events such as floods, can contaminate wells used for drinking water, and even they might damage unconventional toilets spreading human waste into communities (or into food crops) causing deadly and chronic diseases. Thus it is absolutely necessary planning and having sustainable sanitation systems to help preventing such consequences.
