Balance the Ecosystem

Introduction

🌊 Loch Emergent is in your hands. This mountain lake has Fish, Algae, Nutrients, and Water Quality locked in a delicate balance — reinforcing feedback loops that can sustain life or spiral into collapse.

Set the Fishing Rate and run a 20-year simulation. Keep the fish alive without triggering an algae bloom.

🔄 Balancing Loop

Natural Control: Fish Eat Algae

When fish are healthy, they graze algae. Less algae means cleaner water. Cleaner water supports more fish. The ecosystem self-regulates.

Fish ↑ → Algae ↓ → Water ↑ → Fish ↑

🔁 Reinforcing Loop

Eutrophication Cascade: Algae Blooms

If fish decline, algae blooms. Algae degrades water quality. Poor water kills more fish. The same loop — now running in reverse — amplifies collapse.

Fish ↓ → Algae ↑ → Water ↓ → Fish ↓↓
