Is this "impact" collision or effect or influence? If it is the former, how can you tell the two in many different cases?


ex)Errors and failures typically corrupt all human designs. Indeed, the failure of a single component of your carís engine could force you to call for a tow truck. Similarly, a tiny wiring error in your computerís circuits can mean throwing the whole computer out. Natural systems are different, though. Throughout Earthís history, an estimated 3 million to 100 million species have disappeared, which means that this year somewhere between three and a hundred species will vanish. However, such natural extinctions appear to cause little harm. Over millions of years the ecosystem has developed an amazing insensitivity to errors and failures, surviving even such drastic events as the impact of the Yucatan meteorite, which killed tens of thousands of species.
