Usage tips
Separable verb
'Entgegenwirken' (to counteract) is a separable verb. In main clauses, the prefix 'entgegen' comes at the end of the sentence. In subordinate clauses and in the infinitive with 'zu', the verb stays together.
EXAMPLE
Die Regierung wirkt der Krise mit neuen Maßnahmen entgegen.
The government is counteracting the crisis with new measures.
Dative construction
This verb is always used with the dative. You counteract 'etwas' (something) or 'jemandem' (someone). The thing you are working against is in the dative.
EXAMPLE
Wir müssen dem Klimawandel aktiv entgegenwirken.
We must actively counteract climate change.
Word structure
The word consists of the preposition 'entgegen' (against/toward) and the verb 'wirken' (to have an effect). So it literally means to exert an effect against something.
EXAMPLE
Um der Müdigkeit entgegenzuwirken, trank er einen starken Kaffee.
To counteract his tiredness, he drank a strong coffee.

entgegenwirken vs unterstützen
to support
'unterstützen' and 'entgegenwirken' are clear opposites here. When you support something, you help an idea, a plan, or a development and want it to become stronger or succeed. When you counteract something, you actively work against it so that a development becomes weaker or does not happen. So 'unterstützen' fits agreement and help. 'entgegenwirken' fits especially when you want to stop or reduce a negative effect.
entgegenwirken
Die Schule startet ein Projekt, das Gewalt auf dem Pausenhof entgegenwirkt.
The school is starting a project that counteracts violence in the playground.
unterstützen
Wir unterstützen den Vorschlag, weil er die Zusammenarbeit im Team verbessert.
We support the proposal because it improves teamwork.
