On the 20th of December in 2021 it’s International Human Solidarity Day. The United Nations (UN) had acknowledged solidarity as a fundamental and universal value in 2005. This international day is a reminder for how important it is to deal with global issues and challenges together. Acting as a unity is the right way to reach the global development targets. The Secretary-General of the UN marked solidarity as a necessity to fix the problems of the complex world we live in. The global world should feel like a family that acts together and reaches its goals. Individuals should aid one another and feel as a community. Solidarity is a basic to do so and this is what International Human Solidarity Day expresses.
