The ethical concerns surrounding marine parks, exemplified by facilities like SeaWorld, center on the welfare of the animals held in captivity. These concerns arise from the considerable difference between the natural environment of marine mammals and the artificial environments provided in these parks. Orcas, dolphins, and other marine creatures are accustomed to vast oceanic ranges and complex social structures, which are often impossible to replicate adequately within a controlled environment.
Maintaining these animals in captivity can lead to detrimental physical and psychological effects. The limited space often results in abnormal behaviors, such as repetitive swimming patterns, self-harm, and increased aggression. Historically, high mortality rates and compromised immune systems have been documented in captive marine mammals, further fueling the debate about the appropriateness of keeping such animals in artificial settings. Public awareness has shifted significantly over time, emphasizing the intrinsic value of these animals and questioning the justification for their confinement for entertainment purposes.
