The northern white rhino will surely be mourned, as would other stalwarts of picture books, documentaries and soft toy collections. But what about species of which of which we are less fond – or perhaps even entirely unaware? Would we grieve for obscure frogs, bothersome beetles or unsightly fungi? Extinction is, after all, inevitable in the natural world – some have even called it the “engine of evolution“. So should extinction matter to us?

There are far more gorillas left in the world than previously thought, according to a landmark new survey, with numbers as much as double earlier estimates.

However, their populations are continuing to fall fast, down 20% in just eight years, leaving them critically endangered. Furthermore, 80% of the remaining gorilla troops do not live in protected areas, leaving them vulnerable to the threats the researchers summarise as “guns, germs and [felled] trees”.

Animals are dying off in the wild at a pace as great as the extinction that wiped out the dinosaurs about 65 million years ago because of human activity and climate change.

Current extinction rates are at least 12 times faster than normal because people kill them for food, money or destroy their habitat, said Anthony Barnosky, a biology professor at the University of California-Berkeley.
