Debate Kit: Should Marine Mammals Be Held in Amusement Parks?

Free Debate Kit: Exploring the Use of Marine Mammals for Entertainment
A hot topic in classrooms and among the public is whether marine mammals should be imprisoned for entertainment. Here at PETA, we campaign for animal rights and understand that animals are not ours to use for entertainment. We know that many schools assign debates on current issues to help students improve their speaking and writing skills, practice research, and explore multiple perspectives on controversial or complex topics. This student debate kit provides a variety of resources to support the argument that marine mammals shouldn’t be imprisoned for entertainment.
Resolved: Marine Mammals Should NOT Be Imprisoned for Entertainment.

Affirmative Argument
Marine mammals are highly intelligent, sensitive, and social beings, and they suffer greatly when used for entertainment. The chlorine and copper sulfate used to keep tanks clean have caused dolphins’ skin to peel off and may cause them to go blind. Many marine mammals suffer from peptic ulcers, often leading to death, because of frustration resulting from their unnatural lives. Imprisoning animals for entertainment also tears families apart. In their natural habitat, orcas often spend their entire lives with their mothers and siblings and live in large, socially complex groups.
Although the aquarium industry claims to exist purely for education and conservation, the message these facilities really send is that it’s acceptable to keep animals imprisoned for entertainment in cramped conditions, far from their natural homes, where they’re depressed, lonely, and at the mercy of humans. Marine mammal conservation is achieved by abolishing whaling, cleaning up our oceans, ending driftnet fishing, and prohibiting live captures, not by forcing cetaceans to swim in repetitive circles for human entertainment.
There are countless ways to inform the public and cultivate respect for animals without imprisoning marine mammals. It’s time to focus on teaching visitors how to protect marine life rather than harming it.

- Note: Following years of campaigning by PETA and fellow animal rights activists, along with the help of philanthropist and Indianapolis Colts owner Jim Irsay, on March 30, 2023, the Miami Seaquarium announced plans to release the long-suffering orca Lolita to a sea sanctuary off the coast of Washington state. Unfortunately, this move came too late. She died in August 2023 after spending more than five decades imprisoned at the Miami Seaquarium in the smallest, bleakest orca tank in the world, deprived of any semblance of a natural life.

Anticipate Counterarguments and Prepare Rebuttals
Analyze aquarium and marine park websites to identify their stated reasons for keeping marine mammals imprisoned. Investigate how much money these organizations generate through ticket sales and other activities, and think critically about their motivations. Also, examine which other entities benefit from keeping marine mammals in captivity (e.g., aquarium suppliers, food vendors, scientists who study only captive animals). Create a list of common statements made by parties who advocate for the continued imprisonment of marine mammals. The information provided in the links within this document can be used to respond to counterarguments.
