The biodiversity: relocation of species
This animation shows that over the course of the Earth's climate's history, species have often had to move in order to benefit from the types of living conditions that suited them. It also demonstrates how, for various reasons, it is impossible for some species to continue being displaced: either they are at the maximum extent of their distribution area (such as the polar bear in the Arctic or the ptarmigan in the mountains), or the rate of change has been too rapid and the species in question have been unable to adjust at the same rate. Or again, in the case of the Iberian lynx, the species has already been weakened by other threats.
