The casualties in Hiroshima and Nagasaki

 In Aug. 1945, the United States dropped atomic bombs over Hiroshima and Nagasaki in Japan. The atomic bomb explosions gave the people living within 1,000 kilometers of ground zero a fatal blow. 75,000 people were killed at the moment of the explosion in Hiroshima. In total more than 140,000 people in Hiroshima and more than 70,000 people in Nagasaki were killed. The number of deaths in the two cities equaled that of the earthquake in Haiti in 2010, which is estimated about 230,000. Even now, the atomic bomb survivors, about 280,000 people, are afraid of cancer caused by radioactivity. Their carcinogenic risk is 1.63 times higher than normal. Nuclear weapons are nothing but ones of mass destruction.
 The U.S army says the bombing of the two cities was necessary to avoid more soldiers’ deaths. I can’t agree with this. There are no valid reasons for the massacre of more than 210,000 civilians. This is a crime against humanity.
  We, all the citizens of planet Earth, must know the fact. We have a responsibility to make a world free of nuclear weapons.
