Hi i need to know the conjugations of these verbs based on wether the sentence is indicative or subjunctive
1. tendremos que conservar agua anque (haber) suficiente.
2. las especies en peligro de extincion normalmente mejoran sus numeros tan pronto como nosotros (hacer) algo para protegerlas.
3. a menos que (ahorrar) agua, tendremos problemas de sequia

The answers are:

Explanation:

As you may know, the subjunctive mood is to talk about things that are possible but not certain, whereas the indicative mood is the opposite (certainity). Thus, the three sentences are subjunctive as they express desire and possiblity, but it's not a fact, as not all of us will save water or do something to protect the danger species.

On the other hand, "haya" is the present for of "haber" for talking about something, in this case "agua" "Hagamos" is -we do-, as it is indeed talking about "nosotros"- we. And finally, same happens with number three, talking about us.
