The dodo's habitat was destroyed by human activities, including the introduction of non-native species such as rats and pigs. These introduced species competed with the dodo for food and resources, and they also destroyed the dodo's nesting sites.
Over-hunting
The dodo was also hunted by humans for its meat, feathers, and oil. The dodo was easy to hunt because it was slow-moving and had no natural predators.
Climate change
Climate change may have also played a role in the dodo's extinction. The dodo's habitat was affected by sea level rise and changes in temperature and rainfall. These changes made it difficult for the dodo to find food and survive.
The combination of these factors led to the dodo's extinction by the end of the 17th century.
