The letter also addresses SeaWorld's claim that they no longer capture orcas in the wild, citing instances where the park has retained rescued animals that could have been released back into the wild. They also note that SeaWorld's "conservation value" is very low:
SeaWorld's rescue and rehabilitation efforts have been struggling to keep up with the incredible efforts of dozens of highly qualified organizations across the country for many years. SeaWorld Entertainment claims $1.5 billion a year in revenue, yet they have spent only $9 million on conservation in the last decade. This translates to only 0.0006 of the company's net revenue being funneled back into research and conservation annually. For every hundred dollars made by the park, less than 1 cent is given back to research benefiting wildlife. Furthermore, most of its rescue work is with animals that are not profitable as performers in its shows. SeaWorld has never released an orca back into the wild.
The letter ends by saying the recent attention to the park is just part of a "growing shift" in public awareness about animals at SeaWorld, and demands that the park "adapt to an informed public."
