Barriers to entry in conservation work

Hey y'all! Hope this allowed... Please remove if not.

I run a small conservation education organization working on making conservation careers more accessable through virtual programming and project building.

I am hoping to start a new program soon and Iam looking for some perspectives on what you think the biggest barrier to entry is or was for you to work in conservation/environmental field. What resources, knowledge, experiences do you think were or would have been the most valuable to you?
