Buy directly from farmers. Encourage community groups to start microenterprise vegetable gardens. If you live in an area subject to very cold weather in the winter, you must have a way to provide heating and cooking in case of a disaster that interrupts your regular supplies of natural gas and electricity. Flames produce carbon monoxide, which can kill you. Pregnant women and children are at special risk of carbon monoxide poisoning.
Fuels are flammable liquids or gases.
Handle with care and competence. You can learn how to do this, if you don't already have this knowledge and experience. Don't use charcoal inside for heating or cooking. Be ready to help a church or community group or neighborhood to set up emergency heated shelters to help those who don't have back-up systems in an emergency. Consider making your own home available to neighbors or others who may need a warm place in the event of a winter emergency.
