"TV shows and movies may have hyped up the zombie apocalypse, making many people dream up different survival tactics if the catastrophe hits. However, there are real life situations that could take place that would call for these tactics. Survival food is one of the most important things to have ready in case of such situations. Rice is a good source of carbohydrates and can keep for up to 10 years, provided that it's stored in a dry place. Beans and canned meat are excellent protein sources that could last up to 3 years. Having the necessary equipment to open cans and cook food is also vital. Emergency situations like earthquakes, hurricanes, tornadoes, and even war can leave a person without the basic comforts for a long period of time. Knowing what gear is necessary to have in order to survive could make the difference."
