Putting a Human Face on Biodiversity
By Stephen Leahy
May 21 (Tierramérica) – Biodiversity is what sustains life on Earth, but we are on the verge of the sixth mass extinction of species in the planet’s history, Ahmed Djoghlaf, executive secretary of the Convention on Biological Diversity, told Tierramérica.
On the eve of World Biodiversity Day, May 22, Djoghlaf underscored that climate change is creating conditions to which plant and animal life cannot react to quickly enough. In turn, the loss of species will aggravate global warming, creating a vicious cycle.
TIERRAMÉRICA: What is the link between climate change and biodiversity?
AHMED DJOGHLAF: Species cannot respond fast enough to changing climatic conditions. The warming oceans are having a tremendous impact on coral reefs and plankton, crucial to marine biodiversity. And combined with over-fishing, this means fish stocks will be effectively wiped out by 2048, recent research shows. That will affect the livelihoods of many millions of people.
At the same time, reduction in plankton means the oceans will absorb less carbon dioxide and climate change will worsen. This is also true regarding deforestation: less forest means more carbon in the atmosphere and less biodiversity. Tropical forests contain most of the world’s biodiversity. Brazil, for example, is home to more biodiversity than all G8 countries combined. (Group of Eight wealthiest countries: Britain, Canada, France, Germany, Italy, Japan, Russia and United States).
On May 22 in New York City we will try and put a human face on this by highlighting the impacts of climate change on the world’s 300 million indigenous people. Many indigenous people live with nature but climate change is undermining their traditions, and the natural resources they depend on.
TA: Why should the public be concerned about the decline in biodiversity?
AD: It is the air we breathe, the food we eat, the medicines we depend on. Biodiversity is what sustains life on the Earth. The Millennium Ecosystem Assessment reported last year that two-thirds of ecosystems are in decline. We are on the verge of the sixth mass extinction in the history of the Earth. The current trend is that 30 percent of all known species will vanish before the end of the century.
TA: People are worried about climate change but have little awareness about the biodiversity crisis. What can be done about that?
AD: This April was the warmest April ever in Europe, and people can see and feel that. Declines in biodiversity are not obvious to us. People don’t know that we rely on only 12 different plants for our food, when it used to be more than 7,000. We are not aware that 85 percent of the medicines in the United States come from plants or animals. We need to raise public awareness that we are undermining life on Earth.
