You assemble a huge team of herpetologists and veterinarians to travel throughout Florida, looking for infected snakes and treating them with a common veterinary fungicide. The humanpower required to seek out snakes across the state makes this an expensive and time-consuming intervention, and even after all that hard work, you estimate that you were only able to treat 30% of infected snakes. You can do this intervention again later if you have enough resources. In NetLogo, click the “treat-infected-snakes” button a single time, which should cause many of the red dots to turn green temporarily. Next, advance 6 weeks/ticks and subtract $200,000 from your budget. Also add 1 charisma point, because people are really happy to see that sick snakes are being cured in their communities!
