Hard disagree. People care about animals because they have faces that trigger their empathy. Plant life is still life. The destruction of plants to feed people is no more moral than the slaughter of an animal. The cutting of a redwood to make a desk is not moral. Many people also lack any kind of principle and make stuff up as they go. They get angry at killing a butterfly, but they don't care at all about killing a wasp. Likewise, people get upset about a pig, but they don't care about carrots. The carrots lack a face, and the wasp lacks pretty wings.
