Climate change is an urgent global problem, having a significant impact on biodiversity. In the context of ecosystems, biodiversity includes the variety of species, genes and ecosystems that exist, playing an important role in the survival of our planet. One of the main impacts of climate change is global warming, caused by increased greenhouse gas emissions. Rising global temperatures are affecting natural habitats, causing geographic shifts for various species. For example, species normally found in cold regions are starting to move towards cooler parts of the Earth. This process disrupts local ecosystems and can have unpredictable consequences. Furthermore, changing weather patterns contribute to seasonal changes, which affect the life cycles of many species. Irregularities in plant flowering times or bird migration seasons can result in disruptions in the food chain. If migratory birds arrive before flowering plants, the availability of food for the birds could be compromised, threatening their survival. Climate change is also triggering an increase in the frequency and intensity of extreme weather phenomena, such as storms, floods and droughts. This is especially dangerous for already vulnerable species, especially those in restricted habitats. For example, increased forest fires as a result of higher temperatures are destroying the habitats of endangered species, such as orangutans in Indonesia and koalas in Australia. Climate change has a negative impact on ocean health. Warming seawater causes acidification, which affects underwater life. Coral reefs, which are the epicenter of marine biodiversity, are experiencing bleaching due to rising temperatures, which can be fatal for thousands of species that depend on them. Changes in habitat and species interactions also arise due to climate change. Invasive species often benefit from changing conditions, potentially displacing native species. For example, non-native fish can populate marine ecosystems and disrupt the existing balance, leading to a decline in local species populations. Human income and dependence on natural resources are also affected. Agriculture, fisheries and forestry are some of the sectors facing challenges due to climate change. If biodiversity is disturbed, the ecosystem that supports human life will also be threatened. Therefore, protecting biodiversity is the key to improving environmental conditions and socio-economic sustainability. Efforts to mitigate climate change are important in maintaining biodiversity. Policies that support renewable energy, emission reduction and conservation are steps that need to be taken. In-depth research into the impacts of climate change on species is also urgently needed to create effective policies. By increasing public awareness and involvement in preserving biodiversity, we are creating a generation that cares more about the environment. This collective awareness will be key in facing the challenges of climate change and protecting biodiversity for future generations.
