-- Awareness Campaign to Promote Biological Diversity --

(Silver Spring, MD and New York, NY) - Discovery Communications and the United Nations announce a partnership to spread awareness of the United Nations global campaign to celebrate the International Year of Biodiversity (IYB). Throughout the year, Discovery will work closely with the Secretariat of the Convention on Biological Diversity (CBD) to increase the understanding of the vital role that biodiversity plays in sustaining life on Earth. To meet the goals of the IYB, Discovery will utilize a wide range of company resources including its education unit, international networks and special programming including LIFE, Discovery Channel's blockbuster BBC co-production.

"Biodiversity is life. Biodiversity is our life. It is critical that governments -- and people around the world -- work with renewed urgency to reduce biodiversity loss. We are pleased that Discovery is supporting the International Year of Biodiversity and helping us to inspire people around the world to take action to safeguard our shared irreplaceable natural wealth," said United Nations Secretary-General Ban Ki-moon.

"During this International Year of Biodiversity, it is important for people to realize that they are connected to nature and have the power to protect it" said Ahmed Djoghlaf, Executive Secretary of the Convention on Biological Diversity. "It is wonderful to have the exceptional experience and talents of the team of Discovery engaged in the International Year of Biodiversity. I want to call on other partners to follow the leadership of Discovery for protecting life on Earth."

"It's fitting that 2010 marks both Discovery's 25th anniversary and the United Nations International Year of Biodiversity. For a quarter century, Discovery has delivered on the original mission of our founder and chairman, John Hendricks, to satisfy curiosity and make a difference. Partnering with the UN builds on this proud tradition and together, we will celebrate our world and remind audiences that we are all stakeholders in our planet's future," said David M. Zaslav, President and CEO of Discovery Communications.

From the makers of PLANET EARTH, the epic television series LIFE is the definitive exploration of our planet's living things and their spectacular, bizarre and fascinating behaviors. Narrated by global media leader and philanthropist Oprah Winfrey, the 11-part natural history series, a BBC and Discovery Channel co-production, begins Sunday, March 21 at 8PM ET/PT on Discovery Channel.
