Is it possible to do without metals in everyday life? Imagine that they suddenly disappeared - no cars, no trains, no machine tools, no ordinary knife and screwdriver! And if metals disappeared altogether, our planet itself would be gone: its iron core would be replaced by a void. The magnetic field that creates the core would disappear, and there would be no one to protect us from cosmic radiation. And without metals, humans wouldn't live a second without them. Without calcium, teeth and bones would crumble into powder, without iron, the blood would stop carrying oxygen around the body, and without magnesium, plants would stop releasing this oxygen. Of course, in a small book can not tell all about the metals and their features. But it is clear: modern man cannot do without knowledge about metals!
