Global drought has a significant impact on biodiversity around the world. As rainfall decreases and temperatures increase, ecosystems experience dramatic changes that can threaten certain species and alter the ecological landscape. One of the main impacts of drought is a decrease in water availability. Plant species, such as rice and corn that are highly dependent on water, are experiencing reduced production, which in turn affects the herbivore and carnivore species that depend on them. In drought-affected areas, many animal species must migrate or adapt to new conditions, leaving them vulnerable to extinction if new habitats are unable to support them. For example, animals living in the desert may adapt by decreasing their activity during the day, but species that cannot adapt quickly will face higher risks. Then, the impact of the drought was also visible in areas affected by forest fires. With a lack of water, vegetation becomes more flammable, which can destroy habitat for many species. Fires trigger changes in species composition, where some species can bounce back more quickly than others, leading to ecosystem homogeneity. Drought can also increase the spread of disease. Some pathogens and pests thrive in drought conditions, threatening trees and crops and causing a decline in the number of species in an area. As a result, there is a decrease in interactions between species, which are important in maintaining ecosystem balance. The socio-economic impact of drought should not be ignored either. When natural resources become depleted, local communities dependent on agriculture and fishing are forced to seek alternative sources of livelihood, often causing further damage to the environment. Meanwhile, endemic species that are highly dependent on certain ecosystems are particularly threatened by changes in the landscape. Biodiversity reduction is not only a local problem but also a global one. When one species goes extinct, its ultimate impact can extend far beyond that species. For example, the loss of pollinating insects due to climate change results in a decline in crop production, resulting in food shortages for humans. Protecting biodiversity in the future requires a collaborative approach. Efficient management of water resources and implementation of sustainable agricultural practices are essential. Investments in research on threatened species and the development of conservation strategies can help maintain biodiversity. Global awareness and data-driven action are needed to face the challenges posed by drought. Natural resources must be managed in a way that ensures the sustainability of the ecosystem. Biodiversity is the foundation for environmental health and human well-being, and appropriate action must be taken to protect it from the negative impacts of global drought.
