For this reason, the author of the text to which the question is referring states that "Alcatraz Island is more suitable for an indigenous reserve," because that island does not have the minimum resources for the indigenous population to be able to live with the basics of comfort. For this reason, to survive, the indigenous population would be forced to submit to the wishes of the white man.
