Chemical fertilizers not only create potential health hazards, they also destroy earthworms, which are highly beneficial to soil. For this reason alone the use of chemical fertilizers should be avoided. The castings earthworms leave behind are much richer than the soil they ingest, thus making a garden rich in earthworms much more fertile than a garden without them.

Summarize Argument
Chemical fertilizers should be avoided. They destroy earthworms, which are good for the soil. Earthworms make the soil richer when they ingest and digest it, making gardens with earthworms more fertile.

Identify Conclusion
The conclusion is the author’s warning: “the use of chemical fertilizers should be avoided.”

A
Earthworms are highly beneficial to soil.
This is support for why chemical fertilizers should be avoided, because they destroy those earthworms.
B
Chemical fertilizers destroy earthworms.
This is support for why chemical fertilizers should be avoided because earthworms have significant benefits. Destroying them causes loss of those benefits.
C
The castings that earthworms leave behind are much richer than the soil they ingest.
This is support that explains why earthworms are beneficial to soil. That in turn supports why earthworm-destroying chemical fertilizers should be avoided.
D
The use of chemical fertilizers should be avoided.
This matches the conclusion verbatim. The argument is dedicated to demonstrating why the effects of using these fertilizers are negative and that they should be avoided.
E
A garden rich in earthworms is much more fertile than a garden that is devoid of earthworms.
This is support that shows why earthworms are so beneficial. This then supports why earthworm-destroying chemical fertilizers should be avoided.
