So what's the big deal? Why should Christians care about the subjugation of Shamu?
The Bible tells us that mankind is special and above all other creation because we were made in the image of God. It is important to accept that with this uniqueness comes responsibility.
In the garden, mankind was given the charge to be stewards of God's creation (Genesis 1:26-28). This charge has sometimes been misinterpreted as permission to subjugate creation. God's intention was for us to care for His creatures with love, just as He does.
In the Old Testament, there are many examples of God's expectation of how we should treat animals (Leviticus 25:6-7, Deuteronomy 5:14, Deuteronomy 22:10, Exodus 23:5, Deuteronomy 25:4, Proverbs 27:23).
In the New Testament, Jesus used God's love for animals to demonstrate how great His love is for mankind (Matthew 6:25-27, Luke 12:6-7).
The problem with keeping orcas in captivity is that they are highly intelligent, emotionally sensitive, and social animals.
In the wild, orcas swim over one hundred miles a day to forage, hunt, play, and socialize. Family is a very important aspect of an orca's life. Unlike humans, some orcas stay with their family for their entire lives.
