The problem starts already earlier:wildlife experts can only estimate the number of species in the world generally!
This is the case because there are simply too many species, and it takes time to documents them; because some areas (ocean bottom for example) are very hard to access and because sometimes it's hard to know whether we're talking about a new species or a variation within the same species.
so if we even don't know how many species there are, it's even harder to know how many are endangered.
One reason why the U.S govt forced the cherokee to give up there land was because the U.S wanted to move west towards califonia because there was gold there during the ''gold rush''.to answer the second question yes the process did kid of help because it created the suburbs for the settlers that moved west over time.
