Climate change is having a significant impact on global biodiversity, affecting the ecosystems, species and ecosystem services that support life on the planet. One of the main impacts is habitat change. An increase in global temperature causes a shift in the distribution area of species. For example, species in cold regions such as the arctic are moving northward or to higher altitudes, resulting in loss of natural habitat. Apart from that, climate shifts also trigger changes in the timing of natural phenomena. For example, the flowering season of plants and bird migration are disrupted. This can disrupt symbiotic relationships between species, such as pollination, impacting plant reproductive patterns and food availability for animals. Disrupted pollination can cause a decline in certain plant populations, which affects other species in the food web. Biodiversity is also threatened by the increasing frequency and intensity of natural disasters due to climate change. Floods, droughts and storms affect ecosystem stability. Additionally, ocean warming causes coral reef bleaching, threatening marine species that depend on coral as habitat. About 25% of marine species depend on coral reefs, and this loss could change entire marine ecosystems. Climate change is fueling invasive species, which can impact local biodiversity. These species are often more adaptive to new conditions and are able to outcompete native species in competition, causing a decline in local species populations. This reduction in biodiversity results in the ecosystem’s vulnerability to disease and further environmental change. In addition, climate change is exacerbating the issue of natural resource exhaustion. Biodiversity loss directly affects important ecosystem services, such as providing clean water, pollination, and plant resistance to pests and disease. With the loss of species, the ecosystem’s ability to recover from disturbances is reduced, creating a negative feedback cycle that can lead to ecosystem collapse. From an economic point of view, impacts on biodiversity affect sectors such as agriculture, fisheries and tourism. Instability of global food markets can occur due to reduced crop yields and threaten food security. In the tourism industry, especially in valuable ecosystems such as national parks, loss of biodiversity can reduce attractiveness to tourists and impact local incomes. Mitigation and adaptation actions are important to reduce the impacts of climate change. Habitat conservation, reducing greenhouse gas emissions, and implementing sustainable agricultural practices are examples of steps that can be taken. Awareness of the importance of biodiversity and its role in the health of the earth is very necessary. Global efforts such as international agreements are also being developed to safeguard and protect threatened species and habitats. Thus, understanding the impact of climate change on biodiversity is key to finding effective solutions. Combining scientific research and real action can help protect our biodiversity and ensure the survival of life on earth.
