Global climate change is having a significant impact on biodiversity throughout the world. One of the main impacts is changes in natural habitat. The increase in global average temperature affects ecosystems, especially in tropical areas that are rich in species. Many species are forced to move to higher altitudes or latitudes in search of more suitable conditions, which are often not available, resulting in population loss and potential extinction. In addition, the increasing frequency and intensity of extreme weather, such as storms, droughts and floods, destroys habitats and affects migration patterns and reproduction of fauna. For example, migratory fish species, such as salmon, are highly dependent on optimal water temperatures. Inappropriate temperatures can disrupt their life cycle, impacting the entire aquatic ecosystem. Climate change is also high frequency, affecting species distribution patterns. Flora and fauna that are unable to adapt quickly will experience extraordinary pressure. Vegetation in boreal forests, for example, is experiencing a reduction in area along with climate change. When key crops fail to survive, the species that depend on them are also threatened. Genetic diversity is threatened by climate change. Species that inhabit limited areas are likely to experience isolation, reducing the genetic pool. Low genetic diversity makes species more susceptible to disease, infection, and environmental changes. Another effect of climate change is an increase in carbon dioxide (CO2) concentrations, which accelerates the acidification process of the oceans. This has serious consequences for shelled organisms, such as corals and molluscs. Damage to coral reefs will have implications for marine biodiversity, because reefs are home to various species of fish and marine animals. Rising temperatures also affect interactions between species, such as predators and prey. Changes in plant growth times can cause timing mismatches between predators and prey, potentially disrupting the food chain. When these interactions are disrupted, ecosystems can become unbalanced, accelerating species decline. Human activities further exacerbate the impacts of climate change. Habitat destruction, pollution, and urbanization reduce the resilience of ecosystems, making them more vulnerable to climate stress. Therefore, habitat protection and restoration is essential to maintain biodiversity. International collaboration is also needed to face the challenges of climate change. Developing inclusive adaptation and mitigation strategies can help protect species and habitats. An ecosystem-based approach, which respects the interdependence between species, must be part of policies to maintain biodiversity amidst ongoing climate change.
