In the 1850s, Thomas Austin released approximately twenty-four rabbits from Europe into the Australian countryside. By 1900, tens of millions of rabbits were found all over the Australian continent. The warm Australian climate, abundant farmland, and crops provided the perfect habitat for the rabbits. The rabbits caused extensive damage to all vegetation, and the lack of plants increased soil erosion. Why were the rabbits so successful? 

• the rabbits competed with local herbivores for food
• the rabbits did not have natural predators
• erosion of soil benefited the rabbits
• diseases helped decrease rabbit populations
