Global climate change has become one of the greatest challenges facing the modern world today. This phenomenon is not only related to increasing global temperatures, but also includes a wide range of impacts on environmental sustainability. One of the main impacts is an increase in the frequency and intensity of extreme weather. Natural disasters such as floods, droughts and tropical storms are increasing, resulting in habitat loss and reduced biodiversity. Rising sea levels also threaten coastal ecosystems, especially in areas that depend on mangrove and coral reef ecosystems. Coral reefs, for example, are particularly vulnerable to warming waters caused by climate change. This disrupts the marine food chain and impacts the fish that are a source of income for millions of people. Climate change also affects the availability of clean water. With snow and ice melting in the mountains, many regions are experiencing profound changes in river flow patterns. Areas that previously depended on clean water from snow are now facing the threat of drought, threatening agriculture and the socio-economic lives of local communities. Plant health is also negatively impacted by climate change. Changes in temperature and rainfall patterns disrupt plant growth cycles, increasing the risk of plant disease. This has implications for global food security, especially in developing countries that have less strong agricultural infrastructure. From a biodiversity aspect, climate change causes species migration, coral bleaching, and many species are threatened with extinction. The natural habitats of many animals and plants are being disrupted, and species that cannot adapt quickly are at risk of extinction. Threatened ecosystems can also disrupt important ecosystem services such as pollination, carbon storage, and waste processing. The global economy is also not immune from the impacts of climate change. The costs of recovering from natural disasters are increasing, placing a burden on governments and the public economy. Agriculture, fishing and tourism sectors that depend on the natural environment face significant risks in the long term. Investments in climate resilience and sustainable management of natural resources are urgently needed to ensure economic and environmental sustainability. The transition to renewable energy sources is an important step to mitigate the impacts of climate change. Renewable energy can reduce greenhouse gas emissions which are the main cause of climate change. Apart from that, education about the importance of biodiversity and environmental conservation also needs to be improved to involve the community in environmental conservation efforts. The impacts of global climate change are complex and interconnected. Therefore, the solutions taken must be holistic, combining technology, public policy and community involvement. Efforts to reduce this impact will be an important foundation in ensuring environmental sustainability for future generations.
