Marisa Miller is adding her name to the list of celebrities and well-known voices boycotting SeaWorld. The 36-year-old model, who is pregnant with her second child, posed discreetly naked and motherly in a small bathtub with a message reading: ‘SeaWorld: Separating Babies and Mothers Since 1970. 

“… Orcas at SeaWorld spend their lives in tiny concrete tanks that, to them, are the size of a bathtub,” Miller detailed, referencing her ad campaign. “Because of their confinement, they can only float listlessly, swim in circles and attack one another until they die — usually far short of their natural life expectancy — from injuries, pneumonia or other captivity-related causes. At least 36 orcas have died at SeaWorld — and not one of them from old age.”

SeaWorld’s stock price has lost its luster, although Goldman has issued a buy signal. In the year ended Dec. 31, 2013, sales rose an anemic 2.6% and per-share earnings fell by 33.7%. In 2014, its sales fell by 5.6%, and per-share earnings slid 3.4% to $0.57 per share as fewer people frequented its parks, writes TIME. Last quarter, revenue fell 2.7%. 

SeaWorld shares are down 32% in the last 12 months, prompting SeaWorld to launch a national $10 million ad campaign that includes TV, print and digital messaging. 

Most recently, Jane Goodall, the respected scientist who has devoted her life to working with primates, told The Huffington post that SeaWorld ‘should be closed down.’
