Global warming has become an important issue in the modern era, affecting various aspects of life on Earth, especially biodiversity. Drastic changes in global temperature have a significant impact on ecosystems. Flora and fauna face serious threats due to climate change. This can lead to declines in species numbers, loss of habitat, and shifts in migration patterns. Changes in temperature have a direct impact on natural habitats. For example, tropical forests, which are home to many species, are threatened by rising temperatures and changing rainfall patterns. As a result, species that depend on certain conditions may have difficulty surviving. Plants, for example, often cannot adapt quickly to climate change and can become extinct. In addition, global warming causes polar ice to melt and sea levels to rise. This impacts coastal ecosystems, affecting species such as turtles and seabirds that depend on these habitats. Under these conditions, the number of nesting sites decreases, threatening the survival of the species. Mangroves are also at high risk, as they not only serve as habitat, but also as coastline protection. Changes in temperature also disrupt animal migration patterns. Many migratory species, such as birds and fish, follow temperature and rainfall patterns to find food and breeding sites. However, if they are too late or too early, their mating and survival could be threatened. This creates an imbalance in the ecosystem, which can affect both predators and prey. Increasing extreme weather events, such as floods, droughts and storms, are also contributing to biodiversity loss. Vulnerable ecosystems, such as coral reefs, are very sensitive to rising temperatures and changes in seawater chemistry. Coral reef bleaching is one of the biggest signs of the impact of global warming, which threatens thousands of species that depend on them. Genetic diversity is also threatened by global warming. Geographically isolated species may not have enough genetic variation to adapt to rapid environmental change. This genetic instability causes susceptibility to disease and reduces the species’ ability to survive in the long term. The impact of global warming can also increase competition between species. When new species enter an area due to climate change, they can compete with local species for resources. This can cause a decline in the number of local species, and can even lead to extinction. Biodiversity contributes importantly to the quality of human life, providing resources such as food, medicine, and ecosystem services. With the loss of biodiversity, we will face far-reaching economic and social impacts. Therefore, conservation and protection efforts for threatened ecosystems and species are very important to ensure the preservation of biodiversity in the future. Global warming mitigation measures, such as reducing greenhouse gas emissions and developing renewable energy, are a priority. Protecting natural habitats and implementing sustainable practices in natural resource management are also important for maintaining biodiversity. The world must work together globally to meet this challenge and ensure that biodiversity can survive global warming.
