Answer:
The rate of extinction is faster than the rate of formation of species on earth today.
Step-by-step explanation:
The rate of extinction is the number of specie extinct divided by the time while rate of formation is the number of new specie formed divided by time.
In today's earth, the environmental conditions are not suitable for the formation of new specie from the old specie.
But the changing environment is causing extinction pf many species.
Hence in comparison, rate of extinction is faster than the rate of formation of species.
