States try to limit nuclear tests not only because they are harmful to the environment, but also because these tests mean that new nuclear weapon capabiltites are being developed. Since the end of WW2, there have been efforts to limit and ban further nuclear tests. A significant milestone was achieved in 1963 when the Partial Nuclear Test Ban Treaty was signed.
