One of the unexpected benefits of running the fish farm was that Sarah and Gareth found a lot of interesting things inside the fish.
They discovered that some fish had eaten plastic and other debris that had ended up in the lake. They made it a point to clean up the lake and prevent further pollution.
They also found that some fish had ingested smaller fish that had ingested microplastics. It was a stark reminder of the impact that human activities were having on the environment. Sarah and Gareth decided to spread awareness about the dangers of plastic pollution and encourage others to reduce their plastic use.
