The International Day for Biological Diversity day will be marked on May 22 (Monday) across the globe including Pakistan to raise awareness about preserving endangered habitats. A wide range of events are organised globally to increase the understanding of the important role of biodiversity in our future. Celebrations are organized by: the Secretariat of the Convention on Biological Diversity, which forms part of the United Nations Environmental Programme; many national governments; and a range of non-governmental organizations. Various activities ,are conducted including translating booklets, leaflets and other educational resources into local languages, dissemination of information on biodiversity via schools, colleges, universities, newspapers, radio and television, exhibitions and seminars for students, professionals and the general public, showings of movies on environmental issues, and presentations of programs to preserve endangered species or habitats. Moreover, plantation drives are also arranged for preventing soil erosion. Other events such as competitions for children and youth to take photographs or create artwork centered on the annual theme of the day. In 1992, state and government leaders agreed on a strategy for sustainable development at the United Nations Conference on Environment and Development, also known as “The Earth Summit”, in Rio de Janeiro, Brazil. Sustainable development is a way to meet the needs of people all over the world and ensuring that planet earth remains healthy and viable for future generations. One of the most important agreements reached during the Earth Summit was the Convention on Biological Diversity. The Convention on Biological Diversity came into force on December 29, 1993, and each anniversary of this date was designated the International Day for Biological Diversity. From 2001 onwards, the date of this celebration was moved to May 22 due to the number of holidays that fell in late December. On this date in 1992, the text of the Convention on Biological Diversity was adopted at a United Nations at a conference in Nairobi, Kenya. Each year, the International Day for Biodiversity focuses on a particular theme. Recently, the themes have been: Biodiversity and Poverty Alleviation (2003); Biodiversity: Food, Water and Health for All (2004); Biodiversity: Life Insurance for our Changing World (2005); Protect Biodiversity in Drylands (2006); and Biodiversity and Climate Change (2007); and Biodiversity and Agriculture (2008). The International Day for Biological Diversity is part of a series of activities to focus attention on the Convention on Biological Diversity. The symbol of this convention is a stylized image of a twig or branch with three green leaves. Depending on the background, the leaves may be just outlines or green blocks. Each year a piece of artwork is commissioned to reflect the theme. Details of the artwork are used as symbols for different aspects of the day.
