"consecuencias" in english means: "impact", "effects" and "consequences"
In english, deppending on the context you use one of those words, but in spanish you only have to say "consecuencias" as a general word. But if you want to do a more specific translation, you could translate:
effect/s=efecto/s
consequence/s=consecuencia/s
impact=impacto (this is mostly used for talking about environment)
