Humans operating in the deep sea, at high altitude, or in space require suits to protect them from the environment. Over the decades they've created a wide variety of suits to solve that problem. 

Due to my laziness in captioning you'll have to guess at each of the suits uses. However, these examples, and the ones that follow the jump, are from the Oobject posts Pressure Suits and Diving Suits, so you can look them up there, as well as see more examples at both links.
