Global warming is one of the biggest challenges facing ecosystems and biodiversity throughout the world. The impact it causes is very broad and has the potential to change the balance of ecosystems that have existed for thousands of years. First, changes in global average temperatures result in habitat changes for many species. For example, some animal and plant species are forced to move their habitats to colder areas. This leads to a decline in populations of species that cannot adapt quickly. According to the IPCC report, more than 1 million species are threatened with extinction if the global warming trend continues. Second, melting ice in the Arctic and Antarctic is raising sea levels, which threatens coastal areas. Wetlands and mangrove areas, which are rich in biodiversity, are at risk of being lost due to erosion and flooding. Marine life, including coral reefs, is also affected by rising sea temperatures and water acidification due to CO2 uptake, which causes coral bleaching. Third, global warming contributes to changes in weather patterns that impact ecosystems. Unexpected rainfall can disrupt species’ life cycles, affecting reproduction and food availability. For example, seasonal changes can disrupt the timing of bird migration and plant flowering, thereby affecting interactions between species. Fourth, worsen the spread of pathogenic organisms and pests. With warmer temperatures, many pest and disease species thrive, threatening the existing balance of species. This has a serious impact on the agricultural sector and world food security. Fifth, the impact on genetic diversity is also very significant. With the loss of species, genetic variation that is important for ecosystem resilience is also reduced. Genetic diversity provides the raw materials for the resistance of plants and animals to various diseases and environmental changes. Reducing genetic diversity could result in greater vulnerability to future threats, such as more extreme climate change. Lastly, the interaction between global warming and human activities is exacerbating the situation. Deforestation and urbanization increase greenhouse gas emissions and worsen the impact of global warming. Unsustainable natural resource exploitation practices, such as excessive mining and fishing, threaten remaining species and habitats. To prevent further negative impacts of global warming on biodiversity, immediate action is needed in the conservation and sustainable management of natural resources. This includes habitat protection, ecosystem rehabilitation, and increasing public awareness of the importance of maintaining biodiversity. Collaborative efforts at local and global levels are essential in maintaining ecosystem balance for a better future.
