Global warming is a very urgent environmental problem and has a significant impact on biodiversity throughout the world. The increase in the earth’s average temperature caused by greenhouse gas emissions results in drastic climate change. These impacts can be observed in various ecosystems, affecting plant and animal species and their habitats. Global temperature changes directly affect the migration patterns of various species. Many animals, especially birds and fish, are forced to move to colder areas to survive. This phenomenon can disrupt the balance of the ecosystem and give rise to invasive species that threaten local species. For example, the movement of fish populations can affect the fisheries sector, which has an impact on the economy of coastal communities. Apart from temperature changes, global warming also causes an increase in the frequency and intensity of extreme weather phenomena such as storms, floods and droughts. These events can destroy the natural habitats that many species need to survive. Forests burning due to increasingly frequent forest fires, for example, harm biodiversity by destroying the homes of many flora and fauna. Not only that, global warming accelerates the melting process of polar ice. This has the potential to eliminate habitat for ice-dependent species, such as polar bears and penguins. Data shows that declining sea ice levels in the Arctic have resulted in declines in species populations as a result of difficulties finding food and shelter. Climate change also affects the water cycle and the availability of clean water. Increased evaporation processes and changes in rainfall can result in droughts in some areas and flooding in others, endangering freshwater habitats. Species that depend on clean water environments, such as salmon and amphibians, are particularly affected by this situation. This condition also has an impact on agriculture and global food sustainability. Climate change can affect agricultural output, and when natural resources are disrupted, conflicts between people can arise that worsen social and economic conditions. This instability has the potential to increase threats to wild species that encounter human habitats. Coral ecosystems, which are very rich in biodiversity, are also threatened by global warming. Rising sea temperatures and increased water acidity cause coral bleaching, which leads to habitat destruction for hundreds of fish species. If not treated quickly, this damage will make the coral ecosystem even more vulnerable. Not only is it a direct impact, global warming also creates additional pressure on species that are already threatened with extinction. With decreasing habitat and changing environmental conditions, the chances of survival are becoming increasingly slim. Therefore, conservation efforts must be doubled to protect critical species. Addressing the impact of global warming on biodiversity requires collaborative action from governments, scientists and society. Habitat protection policies, ecosystem restoration, and environmental education initiatives must be promoted so that future generations can inherit a balanced ecosystem. Efforts to reduce greenhouse gas emissions are also an important step to mitigate further impacts on biodiversity.
