When were orcas banned?

Could you elaborate on the context surrounding the ban of orcas? Are you referring to a specific country, region, or international organization that implemented such a ban? When exactly was this ban enacted, and what were the reasons behind it? Was there any public outcry or debate surrounding the decision to ban orcas? Additionally, how has this ban impacted the conservation efforts for orcas and their habitats? I'm eager to learn more about this topic and gain a better understanding of the timeline and motivations behind the ban.
