Pacific Islanders used land bridges, small rafts, and canoes to reach the islands closest to the mainland. To navigate, they use stars and charts made from sticks/shells. In later years, voyaging canoes were developed, it made for smooth sailing. The Pacific Islanders settled in lagoons, so they used outrigger canoes to get around between each island.
After the the Pacific Islanders got settled, and the European colonized the area, there was a rabbit invasion. The reason for the invasion was a man named, Thomas Austin, released 24 rabbits to hunt. The rabbit population kept growing and growing, but they have controlled the problem over the years.
There was a race to develop powerful nuclear weapons. The United States wanted to test these weapons without endangering U.S. citizens. They decided to test them in the Marshall Island, which lies in a Bikini Atoll. After a test, things didn't go so well...as the island was contaminated with radiation. Bikini Islanders were exiled from their homeland and the island isn't suitable for human life.
