The “alarming” rate at which species are being lost could have a severe effect on humanity, conservationists warned today. Targets set eight years ago by governments to reduce biodiversity loss by 2010 have not been met, experts confirmed at a UN meeting in Nairobi, Kenya.
The third Global Biodiversity Outlook report said loss of wildlife and habitats could harm food sources and industry, and exacerbate climate change through rising emissions.
Achim Steiner, the executive director of the United Nations Environment Programme (UNEP), said: “Humanity has fabricated the illusion that somehow we can get by without biodiversity or that it is somehow peripheral to our contemporary world: the truth is we need it more than ever on a planet of 6 billion [people], heading to over 9 billion by 2050. Business as usual is no longer an option if we are to avoid irreversible damage to the life-support systems of our planet.”

Sinking deltas threaten millions of lives

Most of the world’s major river deltas are sinking, increasing the flood risk faced by hundreds of millions of people, scientists report.
Damming and diverting rivers means that much less sediment now reaches many delta areas, while extraction of gas and groundwater also lowers the land.
Rivers affected include the Colorado, Nile, Pearl, Rhone and Yangtze.
About half a billion people live in these regions, the researchers note in the journal Nature Geoscience.
They calculate that 85% of major deltas have seen severe flooding in recent years, and that the area of land vulnerable to flooding will increase by about 50% in the next 40 years as land sinks and climate change causes sea levels to rise.
Climate change opens up a Northeast passage in the Arctic

Arctic Northeast Passage
Two German ships set off on Friday on the first commercial journey from Asia to western Europe via the Arctic through the fabled Northeast Passage – a trip made possible by climate change. Niels Stolberg, president and CEO of Bremen-based Beluga Shipping, said the Northern Sea Route will cut thousands of nautical miles off the ships’ journey from South Korea to the Netherlands, reducing fuel consumption and emissions of greenhouse gas.
