How do humans affect the survival of penguins?

Answer 1

One way in which humans affect the survival of penguins is by altering its habitat. Pollution of oceans is one way humans affect the penguins' survival. Another way is by over-fishing the oceans. Penguins are seabirds and eat fish. Global warming is melting the ice that Antarctic penguins need to roost and breed. In more temperate areas, such as Australia's southern shores where Little Penguins live, introduced species such as dogs and feral cats affect the penguins' nesting sites, killing these small and defenceless birds on land.
