When we hear the word parasite, we almost always associate it with disease and with something that should be eliminated. Although that is partially true, the story of these organisms has another side worth knowing. Parasites have adopted such a successful way of life that they are everywhere. In this article, we explain how they perform crucial roles within ecosystems: 1) they regulate host populations, 2) they facilitate food webs, and 3) they reveal information about environmental health that is invisible to the naked eye. Recognizing their value means looking at nature with a more curious eye —one that appreciates that all living beings, even the most uncomfortable ones, are part of biodiversity. So next time you think parasites should be eradicated, remember: every coin has two sides. And they also have their good side.
