  1. Sometimes, one species going extinct can spark a chain reaction that spreads throughout the ecosystem; for example, if one species of bee goes extinct, all of the flowers that it pollinates will begin to die out, as well. If another species uses those flowers as its primary food source, it could also be affected. In essence, any disruptions in the food chain can have massive repercussions down the line.
