Capitalized:
* As a proper noun: When referring to a specific academic program or department, capitalize it. For example: "I am a student in the Environmental Humanities program at my university."
* As part of a title: When it's part of a title, follow general capitalization rules for titles. For example: "The Environmental Humanities and Climate Change"
Not capitalized:
* As a general term: When referring to the field of study in general, don't capitalize it. For example: "Environmental humanities explores the intersection of nature and culture."
In doubt? If you're unsure, it's generally safer to err on the side of not capitalizing unless it's clearly a proper noun or part of a title.
