Final answer:
To better reflect the difficulty of overfishing, the simulation should consider the impact on the marine ecosystem, include social and economic consequences, and simulate the long-term genetic effects of overfishing.
Step-by-step explanation:
The simulation could better reflect the difficulty of overfishing by incorporating the following aspects:
1. Consider the impact of overfishing on the entire marine ecosystem, not just the target species. Overfishing can lead to a radical restructuring of the ecosystem, affecting other species and disrupting food webs.
2. Model the social and economic consequences of overfishing, such as the loss of an inexpensive protein source and the increased cost of living for communities that rely on fisheries.
3. Simulate the long-term genetic effects of overfishing, as selective fishing can lead to genetic changes in life-history traits. This can have profound effects on species and their interactions in the ecosystem.
By incorporating these aspects, the simulation would provide a more comprehensive understanding of the difficulty of overfishing and its consequences.
