If the oxygen is turned off for five seconds,

 If  the oxygen is lost from the earth for five seconds, then the oxygen will be lost for five seconds. We can all breathe for a minute, but here's not our whole earth. People lying on the beach will burn quickly... because the air-conditioned maliculaor oxygen protects us from the ultraviolet light. By day the sky will turn black and darkness will spread. All metal-made things that are separate will be welded together before they are immediately connected. Because the air-conditioning layer prevents them from connecting. Forty-five percent of the earth is made up of oxygen. As soon as the oxygen disappears, the whole earth becomes a stone, it will be difficult to move on. We will lose 21 percent of the air pressure so our ear pressure will burst. Oxygen helps the concrete to remain frozen on the ground. The concrete is made of oxygen as soon as it disappears.
