The correct answer to this open question is the following.
If the question refers to the Westward Expansion from 1807 to 1912, that made thousands of pioneers to cross the Oregon Trail, then some possible consequences of the rapid settlement of Oregon would be the occupation of lands to be used as farms and get people new opportunities to make a decent living growing crops. The rapid settlement was notorious by 1840. Oregon lands "promised" fertile soil. That is why people from the Mississippi Valley decide to move to Oregon. Mane Eastern farmers decided to better move to Oregon instead than New Mexico or California, thinking that the land in Oregon was more fertile to farmland. People had to cross the above mentioned Oregon Trail, knowing that the trip would not be easy.
