Why did president andrew jackson remove the native americans from the south in the 1830s?

In the beginning of the 1830s, nearly 125,000 Native Americans lived on millions of acres of land in Georgia, Tennessee, Alabama, North Carolina and Florida-land their ancestors and occupied for years. But since the white men settled, they had president Jackson sign the papers of the Indian Removal Act so they could grow cotton on the Indian's land. So while they were growing cotton and living in luxury, the Indians (Cherokees) to a long way to the west while thousands died along the way.
