International Day for Biological Diversity is celebrated worldwide on May 22 to further our understanding of biodiversity issues. This year, the International Day for Biological Diversity highlights ‘Forest Biodiversity’ to complement the International Year of Forests 2011, declared by the UN General Assembly. The International Year of Forests gives us an opportunity to renew our awareness of the state of the world’s forests, and to realize their role in greening the environment, sustaining life, and providing for people’s needs and wellbeing.
