Other than having a source of drinking water, shelter is your top priority in most survival emergencies. Severe weather conditions can kill within a few hours if you don’t have some type of shelter to defend you from the elements. Luckily, there are a wide array of techniques and materials (wherever you may be) for escaping the elements. Additionally, under "normal" conditions, it is helpful to learn techniques for heating, cooling, cleaning and filtering your indoor environment.
