According to Tom Brown, the basic plan for survival is in the order of shelter (including clothing), water, fire, and food. Cody Lundin writes about the "Rule of 3s"; this relates to human survival without basics: three minutes without air, three hours without shelter, three days without water, or three weeks without food.
Inhumans
Even without using the Terrigen Mist, the Kree modifications, combined with centuries of selective breeding, have given all Inhumans certain advantages. Their average lifespan is 150 years and an Inhuman in good physical condition possesses strength, reaction time, speed, and endurance greater than the finest of human athletes. Karnak and other normal Inhumans who are in excellent physical shape can lift one ton and are physically slightly superior to the peak of normal human physical achievement. Exposure to the Terrigen Mist can both enhance and in some cases reduce these physical capabilities. Most Inhumans are used to living in a pollution-free, germ-free environment and have difficulty tolerating Earth's current level of air and water pollution for any length of time.
