9/11 was a very sad moment that occurred in the US. About 3000 people died and 600 were injured. It left a impact on the world and can show how horrible things can happen. About 400 of the people that died were firefighters and police that died trying to save others. I feel as if we are very lucky that some of us haven't gone through anything like that.
World War II, also known as the Second World War, was a global war that lasted from 1939 to 1945. Queen Elizabeth II served as a mechanic during World War 2. I think that it was to brutal that Germany made children fight at the age of 12 and up. I feel that we should try to stay away from anything like that unless necessary. Watch to 1:00
Human testing is a very inhuman thing to do. It is when scientists test chemicals,substances,etc on humans. Sometimes the human isn't able to control if they are going to be tested on or not. I learned that Nazis did human experimentation called Nazi human experimentation which was a series of medical experiments on large numbers of prisoners, including children, by Nazi Germany in its concentration camps in the early to mid 1940s, during World War II and the Holocaust. I think that all human testing should be banned unless it is medical.
