Final answer:
Gaylord Perry did not contribute to the cause of environmental protection; instead, he was a key figure in the LGBTQ rights movement, and his activism focused on equality and civil rights rather than environmental issues.
Step-by-step explanation:
Gaylord Perry did not directly contribute to the cause of environmental protection; rather, he was a prominent figure in the LGBTQ rights movement. His efforts were primarily focused on fighting against discriminatory policies, supporting victims of a tragic fire in a New Orleans gay bar, and participating in LGBTQ advocacy events, such as the National March on Washington. While Perry's contributions were significant to civil rights, it appears there may be some confusion between his activism and environmental protection efforts, which are two distinct areas.
The provided information highlights significant environmental efforts by politicians and activists, such as the creation of the Environmental Protection Agency (EPA) under President Nixon and the Sierra Club's protests against improper actions by the Department of the Interior, but does not mention any direct contribution by Perry to environmental causes.
