The most striking similarity between these two explorers was their ruthless nature towards the natives they encountered on their various journeys. Both men wanted to extract as many resources as possible from the conquered peoples.
The effects on their health was that widespread epidemics of viruses broke out like smallpox, tuberculosis, and typhus.
