In Canada, the record heat of the past few weeks, when temperatures reached 50 degrees, also caused serious damage to marine animals. According to scientists from British Colombia University, more than a billion marine species have died, boiled in water in the heat.
Using infrared cameras, temperatures were measured, recording levels above 50 ° C along the coast. While mussels can regenerate over the course of two years, starfish and clams live for decades and reproduce more slowly.
The mass death of crustaceans also has serious consequences on water quality because mussels and clams help filter the sea. Mussels, clams, sea snails and starfish rotted in the shallow water. All this has contributed to making the air unbreathable due to the bad smell.
Christopher Harley, of the University of British Columbia, said: "The shore doesn't usually creak when you walk on it. But there were so many empty mussel shells that you couldn't help but step on dead animals as you walked."
Chinese Mine is driving guinea chimpanzees to extinction
A gigantic iron mine in Guinea threatens to permanently extinguish the chimpanzee, already at risk of extinction, being on the IUCN red list. Building the necessary infrastructure would cost many animal lives and the destruction of a habitat that is now small and essential for the small number of chimps left.
The unexploited iron mine, the largest in the world, is located in the Simandou mountains, and is now owned by China, despite being in Guinea. The deposits contain more than 8.6 billion tons of iron ore with an average mineral content of 65%.
According to the IUCN, in 2016 the population of western chimpanzees decreased by 80% from 1990 to 2014. It is therefore one step away from extinction in the wild. The entire area of Guinea is home to nearly two-thirds of the remaining 52,800 western chimpanzees estimated to be in the wild,.
According to a Reuters analysis of satellite images provided by Planet Labs, extensive tunnel work has been underway for several months. An image from June 28 shows two main construction areas at either end of the tunnel, connected by a new access road through the mountains.
To carry out the construction of the infrastructure, the Chinese must blow up a railway tunnel in what is the habitat for a species of chimpanzee in danger of extinction. Unbelievable but true: it would seem that the permissions would be given.
