Feral goats were introduced by humans to the islands for agricultural reasons have had a huge impact on the ecosystem. Feral goats are dangerous to the environment because they eat everything in sight, destroying many habitats. These goats do not have natural predators, thus their population continues to grow which leads to a decrease in other organisms they prey on. The goats have had a huge impact on a specific species on the island, the Galapagos tortoise. The goats would eat all of the food and resources needed by the tortoises, eventually driving the tortoises towards extinction.
