Eating meat is not cruel or unethical; it is a natural part of the cycle of life. Vegetarians mistakenly elevate the value of animal life over plant life. Research shows that plants respond electrochemically to threats and may feel fear, [98] so vegetarians are also causing harm every time they kill and eat a plant. Every organism on earth dies or is killed, at some point, so others organisms can live. There is nothing wrong with this cycle; it is how nature works.
