Figure 7.35: Humans have caused many extinctions by introducing species to new places.
For example, many of New Zealand’s birds have adapted to nesting on the ground. This was
possible because there were no land mammals in New Zealand until Europeans arrived and
brought cats, fox and other predators with them. Several of New Zealand’s ground nesting
birds, such as this flightless kiwi, are now extinct or threatened because of these predators.
