Pretty much everyone should have at least 30 days of emergency supplies. Natural disasters occur in virtually every corner of the world. The "Prepper" term is only derogatory to morons who expect someone else to come and save them after a natural disaster. I live in hurricane country, I used to live in Earthquake country. Suffice it to say, I have lived through major earthquakes (1989 East SF Bay), several scary wildfires, and a couple of hurricanes. We have gone over two weeks without power and had roads blocked by fallen trees. If you don't prepare for an unexpected event, you are going to be very unhappy when it actually happens.
