"the americans supported the indian removal act because the colonies wanted their lands. they were tired of constantly crossing boundaries with the indians' hunting grounds and such. americans also considered indians to be savages. they constantly fought with each other. so the indian removal act forced indians to move west, this being known as the trail of tears. thousands of indians died on this journey."
Before the panama canal people from East coast of America who wanted to go to Asia had to either sail around south America which took months or sail towards Asia and go around Africa which took even longer. The panama canal was a short cut right in the middle of central America which cut navigation time in half. Hope I helped. :)
