In some places, so many animals have been caught from the wild that their local population has started to decrease.
How long till it's the worldwide population?
Being taken from the wild is very traumatic, sometimes it damages an animal's mental health.
Because they are so intelligent, it is thought that, like us, dolphins can suffer from depression.
They stop vocalizing, swim in circles constantly, can become aggressive, and may even harm themselves.
I am not an expert, but I leave you with this, the choice cetaceans (whales, dolphins and porpoises) don't have.
Would you give up a free life with friends, family, and the choice to swim wherever you want, to live in a concrete tank, many times smaller than your original home?
Think about it!"
