Appendix I: Letters of support

Letter of support from scientific experts

We've asked scientists to write letters of support to substantiate our scientific decisions in this methodology. Specifically:

• Biodiversity scientists. Biologists and specialists in entomology, herpetology, ornithologists, marine science, primatology, and apex predators.

• Advocates. Organizations with a long track record in preserving species. There are fantastic foundations across the globe with the influence and track record to comment intelligently.

• Indigenous groups and advocates. Anthropologists, sociologists, ethicists, linguists, and ethnologists who truly understand the lifestyle, needs, and business practices of Indigenous groups and are capable of advocating for them on a global stage.

Letters are included before in order of submission.
