Read the excerpt from E. O. Wilson’s “The Environmental Ethic.” Why should we care? What difference does it make if some species are extinguished, if even half of all the species on earth disappear? Let me count the ways. New sources of scientific information will be lost. Vast potential biological wealth will be destroyed. Still undeveloped medicines, crops, pharmaceuticals, timber, fibers, pulp, soil-restoring vegetation, petroleum substitutes, and other products and amenities will never come to light. It is fashionable in some quarters to wave aside the small and obscure, the bugs and weeds, forgetting that an obscure moth from Latin America saved Australia’s pastureland from overgrowth by cactus, that the rosy periwinkle provided the cure for Hodgkin’s disease and childhood lymphocytic leukemia, that the bark of the Pacific yew offers hope for victims of ovarian and breast cancer, that a chemical from the saliva of leeches dissolves blood clots during surgery, and so on down a roster already grown long and illustrious despite the limited research addressed to it.

Which techniques does Wilson use in this excerpt to convey important information to his readers?

B.

Wilson uses metaphors that appeal to a wide range of the reader’s senses.

answer:   a good wench, give it me.

iago

good girl, give it to me.

emilia

what will you do with ’t, that you have been so earnest

325to have me filch it?

emilia

and what are you going to do with it? why did you want it so much that you begged me to steal it?

iago

  why, what is that to you?

iago

what’s it to you?

emilia

if it be not for some purpose of import,

give ’t me again. poor lady, she’ll run mad

when she shall lack it.

emilia

if you don’t need it for some important reason, then give it back to me. poor lady, she’ll go crazy when she sees it’s missing.

iago

be not acknown on ’t,

330i have use for it. go, leave me.

iago

don’t admit to knowing anything about it. i need it. now go, leave me.

exit emilia

emilia exits.

i will in cassio’s lodging lose this napkin

and let him find it. trifles light as air

are to the jealous confirmations strong

as proofs of holy writ. this may do something.

335the moor already changes with my poison.

dangerous conceits are in their natures poisons

which at the first are scarce found to distaste,

but with a little act upon the blood

burn like the mines of sulfur.

i’ll leave this handkerchief at cassio’s house and let him find it.to a jealous man, a meaningless little thing like this looks like absolute proof. this handkerchief may be useful to me. the moor’s mind has already become infected with my poisonous suggestions. ideas can be like poisons. at first they hardly even taste bad, but once they get into your blood they start burning like hot lava.

enter othello

othello enters.

    i did say so.

340look, where he comes. not poppy nor mandragora

nor all the drowsy syrups of the world,

shall ever medicine thee to that sweet sleep

which thou owedst yesterday.

here he comes. no drugs or sleeping pills will ever give you the restful sleep that you had last night.

othello

    ha! ha! false to me?

othello

argh! she’s cheating on me?

iago

why, how now, general? no more of that.

iago

oh, general, , no more of that!
