With Antarctica becoming an increasingly popular tourist destination, people are asking how the presence of humans affects this isolated and pristine ecosystem. Research has been conducted in Antarctica to specifically find out how humans are affecting penguins. This research involved observing penguin behaviour and collecting blood samples from the animals. From this, scientists were able to analyse the behaviour of penguins when they come into contact with humans, as well as measure there stress levels physiologically.
