The increased migration and increased population that the United States saw during (any) era are examples of "<span>c. demographic and environmental changes," since these have to do mainly with population distribution. </span>
Northern places like Canada were colonized by France. The mid part was at first colonized by the Dutch but then the colonies were taken by the British. The central American part, including South America and the Carribean was mostly controlled by the Spanish.
