International Human Solidarity Day 2025; December 20th.

FORUM: “A call for unity and action.” International Human Solidarity Day 2025. Solidarity is the principle that recognizes our common humanity and the interconnectedness of our destinies. It highlights the need for collective effort, cooperation, and mutual understanding to solve complex challenges such as poverty, hunger, climate change, and conflict. This day serves as an opportunity to celebrate achievements made through solidarity and to recommit to building a more just and equitable world. To promote human solidarity, it is important to actively engage in your community, and get involved in different activities and events. This means helping out and supporting causes that help people who are in need. By doing this, we can bring people from different backgrounds together and help them understand each other better. It’s also important to support local projects that help address homelessness, education, and health. In this way, we show compassion for our community members, making sure every individual is cared for. Follow the conversations with the hashtags: #SolidarityDay, #20December, #HumanSolidarityDay, #TheWorldWeWant, #PromotingSolidarity, #LeaveNoOneBehind.

Our planet is under strain like never before: Temperatures are rising, biodiversity is collapsing, and nearly every person on Earth breathes unsafe air.

Yet there is hope.

Now is the time to invest in resilience, commit to justice, and remember what we are fighting for.

Sustainability is the bedrock on which all our other ambitions rest. Peace, prosperity, equality — none of these exist without a planet to exist on.

Now is the time for courage and creativity.

We must rapidly scale solutions on a range of challenges — from water management and climate resilience, to mining metals and the environmental footprint of Artificial Intelligence.

With the tide turning in favor of renewables, and the help of the next generation, transformation is within reach. We must transform broken systems, unite policy with science, and share solutions with all.

Now is the time set humanity on a path to protect our only home, for generations to come.

United Nations Secretary-General.
