Human beings are currently causing the greatest
mass extinction of species since the extinction of

The rapid disappearance of species was ranked as one of the planet's gravest environmental worries, surpassing pollution, global warming and the thinning of the ozone layer
Extinction happens all the time. Some species have small populations that depend on a particularly narrow range of food, or habitat, and are vulnerable to even small-scale ecological disturbance. Strictly speaking, if the world has fairly even diversity through time, existing species will become extinct about as often as new species evolve. Extinction is the expected fate of species, rather than a rarity.We do require that you submit one of your own papers.
