Water is essential for life. No living being on planet Earth can survive without it. It is a prerequisite for human health and well-being and for the preservation of the environment.
Water and Biodiversity is the theme for this year’s International Day for Biological Diversity (IDB). The theme was chosen to coincide with the United Nations designation of 2013 as the International Year of Water Cooperation. Focusing on water provides the public with an opportunity to raise awareness about this vital issue, and to increase positive action.
