The impact of global warming on biodiversity is an increasingly pressing issue in the 21st century. With increasing global temperatures, various ecosystems are starting to experience significant changes. One of the main impacts is habitat change. Natural habitats, such as forests, coral reefs and grasslands, are experiencing disruption due to environmental quality degradation. Rising temperatures also result in shifts in species distribution areas. Many species of flora and fauna are forced to move to colder areas, such as towards the mountains or to the north. However, not all species are able to adapt or migrate, especially endemic species that can only be found in certain locations. Loss of home is a serious threat, especially for endangered species. Climate change also has an impact on more extreme weather patterns. Natural disasters such as floods, droughts and storms can destroy habitats and affect food chains. For example, floods can wipe out fish populations in rivers, while drought reduces food availability for herbivores. Interactions between species are disrupted, which can trigger a decrease in the number of predators or prey. A balanced food chain is essential for a healthy ecosystem. When a few species are disturbed, the entire ecosystem can be threatened. An example that often occurs is the loss of top predators that play a major role in controlling the populations of other species. A collapse in the population of this species could lead to an explosion in the numbers of other animals, impacting plant and soil health. In addition, global warming impacts genetic diversity. As habitats change and flora/fauna become increasingly threatened, genetic variation within species is reduced. A decrease in genetic diversity leads to a lack of species’ ability to adapt to new environmental conditions. Species with low genetic diversity are more vulnerable to disease and climate change. Loss of biodiversity not only impacts the environment, but also human health. Healthy ecosystems contribute to the provision of essential resources such as food, water, and medicinal ingredients. For example, forests function as water filters, and a decline in forest quality can threaten the availability of clean water. Likewise, without forests, we lose many plant species that have potential as medicines for various diseases. So, the impact of global warming on biodiversity is a complex issue and has far-reaching implications. Efforts to mitigate climate change and preserve biodiversity need to be carried out simultaneously to protect the environment and human welfare. Educating the public about the importance of biodiversity and the actions that can be taken to conserve it is also very important. Through better knowledge, society can contribute to efforts to face the challenges caused by global warming.
