ANIMAL IMPACT SIMULATOR

Make the small bodies visible.

Compare two plant-forward interventions with assumptions you can see, change, and take with you.

Set the scenario

These are estimates, not a prediction.

People reached 100,000

Chicken meals replaced 30% Fish meals replaced 15%

Intervention A · repeat rate 60% Intervention B · repeat rate 35%

Repeat rate is the share of replaced meals that remains replaced. Adjust it to test optimistic and cautious cases.

Fishes

Model note: The central estimate uses 1 chicken and 20 fishes per replaced meal as deliberately editable stand-ins. Actual outcomes depend on meal size, species, and substitution.

Follow the evidence

This tool is designed to make assumptions inspectable alongside evidence. Its starting question is informed by Faunalytics’ review of the small-body problem; the per-meal values above are illustrative defaults, not findings from that review.
