The Charter of the United Nations was ratified on October 24, 1945, now celebrated as United Nations Day.
This year’s UN Day focuses on the many challenges posed by the world’s population hitting 7 billion:
On 31 October 2011, the world’s population is expected to reach 7 billion.
A world of 7 billion poses many challenges: in fighting poverty and disease, in securing education and sustainable livelihoods and in mitigating climate change. But this milestone for humanity can also be seen as an opportunity to renew our commitment to work individually and together for a better world.
A campaign spearheaded by the UN Population Fund (UNFPA), called 7 Billion Actions, seeks to inspire change that will make a difference by highlighting positive action by individuals and organizations around the world. You can read their stories or add your own at 7billionactions.org.
