Global warming is the phenomenon of increasing the average temperature of the Earth’s surface due to the accumulation of greenhouse gases in the atmosphere. The impact is very broad, especially on biodiversity. Biodiversity encompasses the variety of life that exists on the planet, including species of animals, plants, and microorganisms. One of the main impacts of global warming is habitat change which can lead to a decline in species populations or even extinction. One of the most obvious impacts of global warming is drastic climate change. Rising temperatures can cause shifts in climate zones. For example, animals and plants that normally live in cold areas may lose their habitats, while other species that prefer warm climates will spread northward or to higher altitudes. This creates an ecosystem imbalance that can endanger the survival of native species. In addition, global warming causes a decrease in genetic diversity. Endangered species lose the ability to adapt to environmental changes, increasing the risk of extinction. For example, coral reefs experiencing bleaching due to higher sea temperatures threaten many fish species that depend on them for shelter and food. Changing weather patterns also impact the availability of water resources for many species. Dry seasons or more frequent flooding destroy habitats and can cause migration of certain species that struggle to survive. This also has implications for food chains, where predator species are disrupted when their prey populations decrease. Habitat loss due to deforestation which is often accompanied by rising temperatures makes the situation worse. Tropical forests, which are centers of biodiversity, are increasingly threatened by climate change and human activities. This loss not only affects local flora and fauna but also reduces the ability of forests to absorb carbon dioxide, exacerbating the effects of global warming. Pollution also worsens the impact of global warming. Water and soil contamination from industrial and agricultural waste adds stress to ecosystems, making many species vulnerable to disease. Moreover, if species are unable to adapt quickly to environmental changes caused by global warming, they are likely to decline in numbers or even become extinct. Therefore, to protect biodiversity, it is important to reduce greenhouse gas emissions and preserve natural habitats. Conservation efforts, such as controlling deforestation, restoring ecosystems, and sustainable resource management, must be seriously encouraged. Educating the public about the importance of protecting biodiversity is also an equally important step. As part of the solution, tree planting and protection of natural areas should be encouraged. By preserving biodiversity, we not only protect species, but also ensure the health of ecosystems that support human life. Developing ambitious policies to mitigate climate change and adapt to its impacts is a crucial step for the future of Earth’s biodiversity.
