Okay, Sean, here is my lovely polished two cents, which due to economic difficulties, are worthless (i.e. I haven't done my HSC yet either).
Well seeing as you're using good old Huxley in answering the question, I would sugeest that, as the others rightly say, you give a definition of "In the Wild". Then, I would think it best if you considered what the World State has made of the "Wild". You might think that no, we don't need the "Wild", look what the World State has done without it - scientific developments, no disease - but then you might say, at what cost has all this come at? The loss of individuality, once natural processes like birth and relationships have changed to conform to these new ideas of what is "Wild".
You'd have to make alot of reference to John the Savage, and see how he feels when he sees the World State. Think about the Savage Reservation, which appears to be the ultimate extreme of wild (it allows no restrictions upon people - there is natural elements, birth, disease, children... but this side of "wild" seems to be a pun on Huxley's behalf - as though he is saying that these people are 'wild' in the sense of being crazy but that was just my opinion.)
Use alot of quotes - those from the DHC and Mustapha Mond are particularly good - about how they live without nature. Then refer to the debate between Mond and John; John who believes that the World State is suffering without natural elements against Mustapha Mond who believes that nature and truth and beauty must be repressed.
Story of my life.
