What purpose is served by mentioning specific plants like Carnation and Dandelion?

Mentioning specific plants such as Carnation and Dandelion serves to illustrate human bias against certain organisms, which helps to reveal societal perceptions of individual species. By focusing on well-known plants, the discussion can highlight how some plants are valued for their beauty or utility, like Carnations in floral arrangements, while others, like Dandelions, are often considered weeds despite their benefits. This contrast showcases a broader theme of how humans prioritize certain plants over others based on subjective criteria—such as aesthetics or cultural significance—rather than objective ecological importance. This critical examination encourages readers to think about the implications of such biases and reconsider their attitudes toward various forms of plant life.
