Fish are Friends, not Food

Fish are sentient beings with a very complex nervous system and behaviors. They are the most common pets but the most exploited animals as well. They are “harvested” by the billions without any concern for their pain and suffering, or the destruction of their habitat.

Please visit Fish Smarts: Why Fish Are More Than Just Streams of Protein.

Fish are creations of God, who glorify Him/Her by their existence. When we don’t allow them to express their God-given instincts we are going against their life purpose, which like ours, is to be able live our full potential. After all, fish value their lives as much as we value ours.
