A male individual of knobbed hornbill (Rhyticeros cassidix) flying above rainforest near Mount Tangkoko and Duasudara in Bitung, North Sulawesi, Indonesia. Hornbill—vulnerable to hunting due the high value of their meat, casques, and tail feathers—has an important role in forest regeneration and in maintaining large trees density by its capability as a seed-dispersal agent. Moreover, Hornbill is "a true 'carbon superhero' that works silently helping tropical forests to maintain their health integrity (and) to store more carbon, " said founder of the Indonesian Hornbill Conservation Society, Yoki Hadiprakarsa, as quoted in an article on Mongabay._However, the temperature is increasing in Tangkoko forest, a connected area. Thus, due to its dependency on forest and certain types of trees, hornbills are also threatened by climate change. "With trees diminishing, there are no safe places for hornbill pairs to build their nests in large mature trees, " wrote Amanda Hackett in a publication by Wildlife Conservation Society. "When hornbills are lost, the nature of the forest will change over the next few decades and centuries, because those plants that hornbills are feeding on and dispersing will become filtered out, " said Rohit Naniwadekar, a hornbill specialist at the Nature Conservation Foundation in India, as quoted by Carolyn Cowan in an article published on Mongabay. "There would also be knock-on effects on forest carbon storage, " Carolyn added._Many tropical forest areas in the world suffer from global warming: new temperature averages have applied, according to a publication on Phys.Org. The International Union for Conservation of Nature (IUCN) added that it has led to ecological, behavioral, and physiological changes in wildlife species and biodiversity. "In addition to increased rates of disease and degraded habitats, climate change is also causing changes in species themselves, which threaten their survival, " they wrote.
