Since nuclear weapons testing began on 16 July 1945, nearly 2,000 have taken place. The history of nuclear testing is one of suffering, with victims often from the most vulnerable communities of the world. Devastating consequences are not confined by international borders and they encompass impacts on the environment, health, food security and economic development. On 2 December 2009, the 64th session of the UN General Assembly declared 29 August the International Day against Nuclear Tests. It is our hope that one day all nuclear weapons will be eliminated. Until then, there is a need to observe this International Day as the world works towards promoting peace and security.
