Every day, newspapers are filled with articles about natural disasters like floods, earthquakes, and hurricanes. These emergencies can occur in every country in the world, so it’s important to be ready for them. There are three important things you should do at home to prepare.
    First, stock up on emergency supplies. You should keep enough food and water for at least three days in your house. Choose food that can be stored for a long time and food that can be eaten without cooking. Canned foods such as soup, fish, meat, and fruit are good choices. You can also store dry foods like crackers and cookies. Be sure to store food that you like and[17]include a few special treats like candy or nuts. In an emergency situation, it’s nice to have something to cheer you up. In addition, think about equipment you might need for the kinds of disasters that happen in your country. You might need blankets, very warm clothes, flashlights, or plastic bags. Think about possible situations, and buy things that would be needed.
    Finally, plan what you will do in case you need to evacuate your home. Decide where you will go. It’s good to arrange a meeting place in advance—such as a relative’s home or a big public building. Also, plan a way to contact other family members if you become separated. Be sure that all family members know the phone number of a contact person in another city.
    People don’t like to think about natural disasters, but a little bit of preparation can save lives. Following these steps will help you be ready for any kind of emergency.
