Cycles. Six letters, two syllables,
one word. Yet, this word is a significant one, as I believe it is the most
important word in chapter five of Silent Spring. This word, although small sums
up Carson’s
argument in chapter five fully and clearly.
In chapter five, Carson goes into the complexity of the soil
and its different relationships. Low and behold, these relationships happen to
be in cycles. For example, there is the relationship between the soil and the
earthworms. The earthworms feed on the enriched soil, they aerate it by digging
holes and bring the good soil to the top, help nitrate it for smaller
organisms, and their excrement helps enrich the soil again. Every organism therefore has its place and
purpose. Thanks to DDT and other insecticides, these perfect, cyclical
relationships have been disrupted or broken. Studies have shown that “BHC,
aldrin, lindane, heptachlor and DDD all prevented nitrogen-fixing bacteria from
forming the necessary root nodules on leguminous plants”. (pg 57) Cycles could
not be more important in this chapter because they are the clock that nature
runs on, as Carson
shows. Even her structure in this chapter was a cycle. She goes from writing about
how the soil is the basis of life and is constantly changing, to the small
bacterial organisms that effect the soil , then the larger ones like earthworms
and how the insecticides are affecting them and then to the human race and how we are being
affected by the soil’s destruction. Carson
even gives a great example of how a company that makes baby foods got into
financial woes because they refused to use food from pesticide treated land and
couldn’t find any. Instead of coming back to the beginning of the cycle with
the soil being left alone, Carson shows
what it is like when the soil is destroyed, showing the plight of Hops growers
in Idaho , where Heptachlor destroyed their soil and therefore their crops. By structuring
her chapter like this, Carson
shows the effects of this broken soil cycle.
The circle of life, it’s a path
unwinding. (Thank you Lion King!) That’s exactly what Carson stylistically shows in her writing in chapter
five. A perfect example of this is when she says “The soil exists in state of constant
change, taking part in cycles that have no beginning and no end” pg 53). In doing
that she creates almost a visual of this cycle and something that people can understand
and relate to. Its almost as if she has a reverence for the cycle, even pointing
out that pointing out the soil supports the
earths “living green mantle” and that’s because its constantly changing. She
remains with this tone throughout the chapter. So in chapter five… cycles.. they’re
important.
