    If the ozone layer is destroyed, most living things on the earth will disappear.

    Good evening teachers! Could you please help me with those sentences:

    1) If the ozone layer is destroyed, most living things on the earth will disappear.
    2) If the ozone layer were destroyed, most living things on the earth would disappear.

    I personally think that two of them are correct. Because the conditional 1 prefers to something that may happen in the future, it is correct. It is correct or incorrect in the second sentence because it is unreal at present but in the future, it will probably take place. Which one is correct or two of them?

    I agree.
    I'm not a teacher. I speak American English. I've tutored writing at the University of Southern Maine and have done a good deal of copy editing and writing, occasionally for publication.

    The second sentence refers to an imaginary present -it isn't true- or an unlikely future. If you want to say that something will probably take place, use the first conditional.
