the killer whales are extraordinary animals endowed with great sensitivity and emotional fragility. To date, these majestic creatures are exploited by humans for the entertainment and recreation of many people in water parks, forgetting the true nature of these animals. The orcas forced to live in water parks living a life that is not harmonious and happy: they are fed inadequately and for the sole purpose of listening to the instructors, real handfuls of fish thrown into their jaws as if they were filling a garbage bag ; the chlorine with which they are in constant contact, creates real wounds on their corroded skin; the tanks in which not one but many killer whales are forced to live at the same time are shallow and for this reason the killer whales often remain uncovered and under the heat of the sun that drives them totally crazy, making them aggressive and consequently dangerous for the 'man. Can you imagine the torture they go through to get this far? how can they feel? Furthermore, the killer whales living in the parks are artificially fertilized and therefore the young separated from their mothers very early and this causes the mothers to fall into a real depression. On average, the maximum age at which these free and "captive" mammals reach is 70 years for males and even 100 for females, while those forced to live in tanks reach adolescence. We must stop this abuse, we do not need to enslave nature and creatures so precious for our leisure or ego, the human being cannot and must not be a black hole that sins of selfishness and presumption.
