Why Don't Scavengers Get Sick?

The video explores how decomposers and scavengers interact with toxins and microbes in their environment. It highlights the strategies scavengers use to avoid disease, such as quality control in meal selection and microbial combat techniques. The video also discusses the immune system adaptations of scavengers and draws parallels to human vaccination practices, suggesting that humans might learn from these natural processes.
