Natural disasters seem to happen frequently. The environment is changing which is resulting in more frequent weather-related natural disasters. When these things occur, entire villages, cities or geographical regions can be affected. Entire populations of dozens, hundreds, or thousands, of people will require shelter. It is the following days, weeks, or even months that it will take for life to get back to normal after a disaster. During that time, to protect a person from the effects of exposure to the elements, shelter is critical to survival and recovery.
