1. The current species extinction rates are far lower than those in previous episodes.
2. The present species extinction rates are 100 to 1000 times faster than in the pre-human times.
3. The present net species extinction rate is zero.
4. The current species extinction rate is nearly 10 times faster than in previous episodes.
