Do we live in the era of Earth´s sixth mass extinction? Estimates of current biodiversity changes. Current biodiversity crisis is often compared to the live mass extinction in geological history. Here I review the evidence concerning current global extinction, showing that its extent is so far much smaller than was in the case of the live big extinction events. However, global extinction rate is currently quite high, so that if the rate remains the same, the magnitude of the sixth global mass extinction could be reached within next several hundreds years. The topics are now much more vulnerable to animal and plant extinction than is the temperate zone.
