And previous studies have found that tourist boots may leave behind dozens of dangerous pathogens. As tourism to Antarctica increases — more than 10,000 people now visit each year — so may the dangers for wildlife.

However, ecologist Norman Ratcliffe said tourism companies are very careful not to pollute the region, and that there is likely some other reason behind Antarctica's sickly penguins.
