8 Essential Tips from 'Arctic,' the Best Survival Movie in Years

Use Snow For Various Medical Purposes

  • Ice is good for numbing pain, but avoid it when it’s so cold that frostbite can set in in record time.
  • As the film Arctic shows, snow can be used to plug wounds preventing hemorrhage as it induces vasoconstriction. It can still cause frostbite but it might be better than the alternative.

Why foods go bad

Most foods spoil because of the growth of microbes. Preserving food is an attempt to limit microbial growth. Food can be preserved by drying, salting, chilling, or storing in air-tight containers.

  • Drying is the most effective because microbial growth is inhibited.
  • Salting is effective because it removes moisture, creating an environment where microbes cannot survive.
  • Sugar coating can prevent bacterial cells from functioning correctly.
  • Storing in air-tight containers is less effective because there are probably a lot of microbes on the food before you put it in the container. Some microbes are anaerobic, meaning they don't need oxygen.
Food preservatives

Preservatives are used in foods to extend their shelf lives. One of McDonald's Big Mac in Iceland is an example of a long-lasting processed food. It has been on display since 2009, in a glass box. Preservatives that has been discontinued by McDonald's are:

  • calcium propionate that prevents mold growth on bread.
  • sorbic acid that also inhibits mold from cheese
  • sodium benzoate, which inhibits the growth of bacteria in the Big Mac special sauce.
