The Earth’s ongoing nature losses may soon begin to hit national economies, a major UN report has warned.

The third Global Biodiversity Outlook (GBO-3) says that some ecosystems may soon reach “tipping points” where they rapidly become less useful to humanity.

Such tipping points could include rapid dieback of forest, algal takeover of watercourses and mass coral reef death.

Last month, scientists confirmed that governments would not meet their target of curbing biodiversity loss by 2010.

“The news is not good,” said Ahmed Djoglaf, executive secretary of the UN Convention on Biological Diversity (CBD).

“We continue to lose biodiversity at a rate never before seen in history – extinction rates may be up to 1,000 times higher than the historical background rate.”

The global abundance of vertebrates – the group that includes mammals, reptiles, birds, amphibians and fish – fell by about one-third between 1970 and 2006, the UN says. Seeing red

The 2010 target of significantly curbing the global rate of biodiversity loss was agreed at the Johannesburg summit in 2002.

It has been clear for a while that it would not be met.
