Martin Sheen joined some 400 anti-nuclear activists in a mile-long protest march outside the Los Alamos National Laboratory in New Mexico yesterday, the 54th anniversary of the bombing of Nagasaki, Japan. Protestors called for an end to the lab’s production of new plutonium pits, which are the cores of nuclear bombs. The protestors were briefly detained, but won’t be prosecuted. Meanwhile, in Australia, eight women yesterday set off on camels to trek 620 miles through desert lands, a protest of the government’s plan to establish a national radioactive dump site in the central Australian outback. The “Humps Not Dumps” camel expedition will last more than two months.
