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.

Intervention A People reached 100,000 Meals per person 1 Time horizon Chicken meals replaced 30% Fish meals replaced 15% Repeat rate 60% Evidence note Evidence source URL

Intervention B People reached 100,000 Meals per person 1 Time horizon Chicken meals replaced 30% Fish meals replaced 15% Repeat rate 35% Evidence note Evidence source URL

Each intervention has its own reach and replacement mix. Chicken and fish shares within each plan must total no more than 100%. Repeat rate is the share of replaced meals that remains replaced.

Intervention A evidence

No custom evidence attached.

Intervention B evidence

No custom evidence attached.

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.
