"Despite its importance, marine biodiversity — the theme of this year's International Day for Biological Diversity — has not fared well at human hands. Commercial over-exploitation of the world’s fish stocks is severe. Many species have been hunted to fractions of their original populations"
UN Secretary-General Ban Ki-moon (2012)
Water & Biodiversity
The 2013 theme (Water and Biodiversity) was chosen to coincide with the United Nations designation of 2013 as the International Year of Water Cooperation. The theme speaks to the important role of biodiversity and ecosystems in providing for water security, and therefore for sustainable development.
The United Nations General Assembly, by its resolution 55/201 of 20 December 2000, proclaimed 22 May as The International Day for Biological Diversity, to increase understanding and awareness of biodiversity issues. The date designated for the day was chosen to commemorate the adoption of the text of the Convention on 22 May 1992 by the Nairobi Final Act of the Conference for the Adoption of the Agreed Text of the Convention on Biological Diversity.
The day was first created by the Second Committee of the UN General Assembly in late 1993, and the UN General Assembly, by its resolution 49/119 of 19 December 1994, designated December 29th (the date of entry into force of the Convention of Biological Diversity) the International Day for Biological Diversity. However, it was difficult for many countries to plan and carry out suitable celebrations for the date of 29 December, given the number of holidays that coincide around that time of year.
