Blackfish

Blackfish is a power documentary that exposes the condition of orcas in SeaWorld. Orca were once hunted and captured by humans. Being separated from its family and natural habitat the orcas got lonely, frustrated, confused as they were kept in confined isolated tanks. They are forced to swim and perform tricks for tourists enjoyment. Even though they are  treated well by their trainers, living in a confined space physically and mentally affected them as they got bully by other orca, became sad, lonely and even killed humans. These orca should not be living in tanks of water, they should be the ocean where they can freely roam around and be with their family. I recommend you guys watch this documentary. You should be able to watch it on Netflix.
