Global warming is a phenomenon resulting from increased greenhouse gas emissions, which has a significant impact on biodiversity throughout the world. An increase in the earth’s average temperature can change natural habitats, affect species, and threaten ecosystems. One of the most obvious impacts of global warming is an increase in temperature which causes climate change. These changes trigger shifts in weather patterns, including the frequency and intensity of rain, causing some areas to experience extreme drought while others experience flooding. All of this has an impact on biodiversity. For example, plant species that cannot adapt quickly to changes in temperature face the risk of extinction. Apart from that, global warming also causes melting of polar ice and rising sea levels. Coastal habitats such as coral reefs and river deltas will be threatened, as more land is submerged by sea water. Coral reefs, which are home to thousands of fish and other marine species, are at great risk from warming. Ocean acidification that occurs due to increased CO2 also affects the ability of corals to build structures that support life. Shifting seasonal times also affects biodiversity. Many species depend on warming times and seasons to reproduce. For example, migratory birds may arrive early to find a suitable food source, but if the plants they feed on do not grow at that time, then the birds will lack food. In tropical forests, global warming can encourage invasive species to thrive, outcompeting local species that are slower to adapt. This could reduce the diversity of existing species, pushing some species towards extinction. Today, the Amazon forest and other biome ecosystems are becoming increasingly vulnerable to forest fires and deforestation, which in turn affects their extremely rich biodiversity. The decline in biodiversity is also closely related to human health. Healthy ecosystems provide essential services such as food provision, climate regulation, and pollutant absorption. When certain species disappear, ecosystems can become less stable and more susceptible to disease. Birds, mammals, reptiles and various other biological species are currently at high risk due to global warming. According to a report by the International Union for Conservation of Nature (IUCN), more than 28,000 species are considered threatened with extinction, mostly due to rapid and destructive climate change. Restoring these ecosystems requires collective action involving reducing greenhouse gas emissions and protecting natural habitats. Biodiversity is not only an important aspect of the environment, but also key to human resilience to climate change. With species diversity, ecosystems can more easily adapt to environmental changes. Therefore, preserving biodiversity must be a priority in efforts to mitigate the impacts of global warming. With the right policies and actions, we can ensure the sustainability of biodiversity for future generations.
