Like in the picture shown below, there is no place where nuclear weapons are destroying our world's environment.
In the atmosphere, upper atmosphere, underground, or under water nuclear weapons are changing the Earth.
Many countries have done nuclear weapon testing and this effects the environment and the whole world.
The first nuclear test was conducted by the United States on july 16, 1945, durring the Manhattan project, codename "Trinity"
The U.S has carried out 1,030 nuclear weapons test since 1993, the Soviet Union has carried out 715, France has done 210 tests, Britain has done 45 tests, and china has had 43 test. These are only the tests that have been reported and there is still a large number of nuclear testing that has gone on since then. I am surprised the world is as healthy as it is now with all these tests.
Nuclear weapon test explosions have been carried out in many if not all environments: above ground, underground, and underwater. They have occurred in places such as on top of towers, on-board barges, suspended from balloons, on the earth's surface, underwater to depths of 2,000 feet, underground to depths of more than 8,000 feet, and in horizontal tunnels. Test bombs also have been dropped by aircraft and fired by rockets up to 200 miles into the atmosphere. All these tests are destroying our world little by little.
Nuclear weapon tests have been done all over the world. It is estimated that a total number of all the atmosphere harming tests conducted is 438 megatons. That's equivalent to 29,200 Hiroshima bombs. Between 1945 and 1980 when atmospheric testing was being conducted it was equivalent to exploding a Hiroshima bomb every 11 hours. Does that seem like its harmfull to the environment?
Wherever nuclear weapon testing has occurred for whatever reason there have been environmental problems. Radioactivity has leaked into the environment from underground nuclear tests, people's health are being effected by these harmfull weapons as well.
This is a picture of four different types of nuclear tesing.
1. atmospheric 2. underground 3. upper-atmosphere 4. underwater.
