P1. Salmon farming has devastating consequences for wild salmon populations and the ecosystem in which the farming occurs (especially the farming of Atlantic salmon on the Pacific coast).P2. (suppressed premise) We should enact regulations that help prevent environment devastation, especially when entire populations and species are at risk.
C. We should enact regulations on salmon farming (especially the farming of Atlantic salmon on the Pacific coast).
Note: there are multiple ways of reconstructing this. The
important point is that you identify: (i) the conclusion as calling for
regulations, (ii) an explicit premise (or two) citing the negative consequences
of salmon farming, and (iii) an implicit premise which assumes we should
prevent such negative consequences from occurring.
Strictly speaking, the suppressed premise could be left out of the reconstruction.
However, the principle of charity requires that we include it.
