1.The moon ________________________. First of all, there is no air. People must have air to live. Second, there is no water. Nobody can live without water. Another problem is the temperature. It is very hot in the sun and very, very cold in the shade. The last problem is food. Nobody can grow plants or raise animals for food without air and water. In short, without special equipment, life on the moon is impossible.
