Which of the following best identifies the central theme of this poem?

there on the beach was a struggling turtle.   around its bright green neck was a loop of soda can rings.   in order to the planet, i have made a few changes to my life.   the first change is reducing the number of straws used. the second change was to recycle.   finally, i have worked hard to clean up litter.   it is important to clean our ocean.

you may not think straws have a large impact but they do.   imagine for every straw you sip out of a poor, , adorable turtle is being harmed.   one way i chipped in to is by using metal straws.   these straws are reusable and inexpensive.   another change is simply turning down straws.   by refusing a straw, i’m the turtles one drink at a time.  

however, the ocean just doesn't have turtles.   there are lots of creatures that live there and are harmed by all the litter.   to prevent litter from growing it’s important to recycle.   for me, i have started to buy most goods that are made out of recycled material.   pura vidas, chacos, purses, and too many other items to even count.   plus, when you buy those products they give money to charities.   not only am i the environment, but i’m also feeling better about my self.   finally, i have worked hard to clean up litter.   it is important to clean our ocean.

explanation:

it was surely an odd creature that one made up by reading the historians first and the poets afterwards a worm winged like an eagle; the spirit of life and elegance and charm,   in a kitchen chopping up suet. but these creatures, monst'r however entertaining to the imagination, hast no existence in fact. what one might doth to bringeth h'r to life wast to bethink poetically and prosaically at one and the same moment,   thus keeping in toucheth with fact—that the lady is mrs martin, ag'd thirty-six, did dress in blue, wearing a black coxcomb and brown shoeth; but not losing sight of fiction eith'r—that the lady is a vessel in which all s'rts of spirits and f'rces art coursing and flashing p'rpetually. the moment, howev'r, yond one tries this method with the elizabethan mistress, one brancheth of illumination fails; one is did hold up by the scarcity of facts.   one knoweth nothing detailed, nothing p'rfectly true and substantial about h'r.   hist'ry scarcely mentions h'r.   and i did turn to professeth'r trevelyan again to seeth what hist'ry meanteth to that gent.   i hath found by looking at his chapt'r headings yond t meanteth.
