Global climate change is having a profound impact on biodiversity around the world. This phenomenon creates drastic changes in the ecosystem that threaten the lives of various species. For example, increasing global temperatures affect animal migration and reproductive patterns. Many species that cannot adapt quickly enough will face extinction. Climate change also causes habitat destruction. Rising sea temperatures, due to global warming, cause coral reef bleaching. Coral reefs are ecosystems that are rich in biodiversity and are home to various species of fish. When coral reefs die, many fish species lose their homes and food sources, which impacts the entire food chain. Terrestrial ecosystems are also experiencing significant changes. Changes in rainfall patterns have caused some areas to become drier, while other areas face flooding. As a result, species that depend on certain habitats may not survive. For example, penguins in Antarctica face challenges due to thinning sea ice, which impacts their ability to find food. Climate change collaborates with other factors such as deforestation and unsustainable agricultural patterns, triggering greater threats to biodiversity. For example, clearing tropical rainforests for agricultural land reduces habitat areas for many species. This not only kills existing flora and fauna but also disrupts the natural cycle of the ecosystem. One of the serious impacts of climate change is the increased spread of disease. Higher temperatures allow disease vectors, such as mosquitoes, to spread to previously unexposed areas. This could threaten animal species and even humans with an increase in zoonotic diseases. Furthermore, species isolated on islands or small habitats are particularly vulnerable to climate change. With little room to move around, their ability to adapt to their new home is severely limited. Therefore, the reduction of genetic diversity is a serious threat. As a preventive measure, the need for sustainable landscape management and the establishment of conservation areas is very urgent. Conservation focuses not only on protecting threatened species but also strengthening the ecosystem as a whole. Finally, global awareness of the importance of dealing with climate change requires collaboration between governments, researchers and society. Through environmental initiatives aimed at reducing carbon emissions and promoting sustainability, potential negative impacts on biodiversity can be minimized. Thus, joint efforts are needed to protect and maintain our biodiversity amidst the challenges of global climate change.
