I choose the bombings of Hiroshima and Nagasaki because that was the first nuclear bomb ever dropped and I enjoy learning about the WWII.
During World War II The United States of America dropped two bombs named, the Litlle boy and Fat man. The bombings occurred on August 6 and 9th in 1945. Both of the events were in Japan; Hiroshima and Nagasaki.
The catastrophic event was caused by humans becuase of the very intense war that was going on at the time ,and the United States decided to drop a bomb on Japan. The bomb affected the world, because of the explosion. The radiation would now effect future generations to come and cause illness in the surrounding areas. It would also affect the world because of the war that would now come to an end.
In Hiroshima between 90,000-166,000 people were killed out of the 290,000 people that lived there, later on people died form radiation. On top of that 43,000 people that did not live there were killed by the bomb. The bomb also destroyed 70,000 of the 76,000 buildings that were in the country. Meanwhile in Nagasaki 80,000 people died form the second bomb. Both of the bombs completely singed animals and plants. Some plants and animals had actually been genetically modified by the bomb. Hiroshima's and Nagasaki's water was now also contaminated.
The land was greatly affected by the bomb. It was burned and broken down to nothing by the fire. Anything that wasn't completely demolished was taken away by the polluted water and dropped wherever it stopped. Eventually the ecosystems went back to working cities. After the water was clean and the radiation was all gone. This would be an example of secondary secession, because it didn't completely start from scratch like it would in Primary.
