The International Day of Biological Diversity (IDB) is celebrated annually on May 22 around the globe by United Nations. The theme for IDB 2017 is “Biodiversity and sustainable Tourism”. It aims on the opportunity to raise awareness of the important contribution of sustainable tourism both to economic growth and to the conservation of biodiversity. The United Nations in the year 2000 adopted a proposal to proclaim May 22 the International Day for Biological Diversity.
