Carbon chauvinism

Carbon chauvinism is when people believe that only life forms with carbon-based biology - like animals and plants - are important, and don't pay attention to other forms of life that are not carbon-based. For example, not paying attention to bacteria and microbes which do not have carbon, but can still be important for our planet. It's like saying that because humans are important, only things like humans are important, and not paying attention to other life forms.
