Global environmental issues have become a major concern for the international community, along with the increasing impact of climate change, decline in biodiversity and pollution. In responding to this challenge, every country in the world has an important role and responsibility. Collective action is needed to address these issues effectively. One of the most pressing issues is climate change caused by greenhouse gas emissions. Developing countries, which are often most affected by the impacts of climate change, continue to struggle to increase adaptive capacity. Through international cooperation, for example, within the framework of the Paris Agreement, countries can support each other in reducing emissions and developing renewable energy. On the other hand, the biodiversity crisis requires action to restore habitats and protect threatened species. Countries need to develop policies that encourage sustainability in the use of natural resources. Conservation programs that prioritize local community participation have proven effective in ensuring ecosystem sustainability. Pollution is another problem that requires serious attention. Plastic waste, air pollution and dangerous chemicals affect human health as well as the environment. Countries must work together to regulate waste and create clean technologies that help reduce negative impacts on the environment. The role of international organizations such as the UN is critical in coordinating global efforts, facilitating dialogue between countries, and providing funding for environmental projects. Through programs such as the UN Environment Program (UNEP), it is hoped that awareness of environmental issues can be increased. In the context of individual responsibility, awareness of the world community is also crucial. People can contribute through sustainable living practices, such as reducing plastic use, saving energy, and adopting an environmentally friendly lifestyle. Education about the importance of the environment needs to be promoted to encourage behavior change. The role of the private sector is also no less important. Businesses must integrate sustainability principles in their business models. Corporate Social Responsibility (CSR) is one way to show a company’s commitment to environmental issues. By investing in green technology, companies not only reduce negative impacts but also create new opportunities. Collaboration between governments, non-governmental organizations, the private sector and civil society is key in resolving global environmental issues. Through the right policies, technological innovation and collective awareness, the world can move towards a more sustainable future.
