The theme of International Peace Day for this year is "Climate Action for Peace".The theme draws attention to the importance of combatting climate change as a way to protect and promote peace throughout the world.
Climate change causes clear threats to international peace and security. Natural disasters displace three times as many people as conflicts, forcing millions to leave their homes and seek safety elsewhere. The salinization of water and crops is endangering food security, and the impact on public health is escalating. The growing tensions over resources and mass movements of people are affecting every country on every continent.
