Intellifive - THE DOMINO EFFECT    The domino effect is a chain reaction that occurs when a small change causes a similar change nearby, which then will cause another similar change, and so on in linear sequence. This effect is an analogy to the row of dominoes, if you hit one, all will fall down one by one. Apart from having significant usage in Mathematics, Physics and economics, the domino effect also has an important usage in environment. Take food chain for example-if a specie dies, the species depending on it will die and so on.
