Which type of seal or sea lion is more likely to become extinct: the Australian sea lion or the northern fur seal? In one or two sentences, explain your reasoning. (2 points)

The Australian sea lion is more likely to become extinct compared to the northern fur seal. This is because the Australian sea lion has a smaller population size and is more vulnerable to human activities such as fishing and habitat destruction. Additionally, the northern fur seal has an overall larger population size and is not as geographically isolated as the Australian sea lion.
