Changing The Past Is Not The Answer (bubble)

Changing something in the past can be a risky thing. Some people would say to go back and change the past would be great, but do they really looks at the things that could happen after they go back a make a change. History teaches us lessons, which make us stronger. To change the past would be very dangerous for the reasons, which could follow including, selfishness, we will never learn from our mistakes, and it would change the future forever.
Changing our past is something that many people will be very selfish about and not agree on. One example is World War II against Germany If we changed the outcome then we would be controlled by the Germans, and not have the freedom that we now enjoy. For selfish reasons, someone might decide to change something for themselves and it may sound better, but what about the many others who have died? When people do for themselves, it shows they do not have respect for many others in need. To change such a major event could be a problem, and many people would not agree on what to change.
Freedom from racism, terror, and slavery is or has been fought for throughout history. From the time the event happens to the time we have fought we try to deal with life. Life is not magic. If life were that easy the world would be very uneventful. The world would never have anything bad happen, but people also would not get hurt having to fight. As a citizen of a free country I know how hard you have to work for things. If we could use the help of time travel we would not learn from the many mistakes we make. If we did not fight, we would never learn how to work for the things we treasure the most.
When people think about all of the terrible things, which happen, all children in school are learning about them and why they happen. If we changed or stopped these things in the timeline, all of the lessons will be forgotten, and all the time-spent teaching would be useless. Every person knows why these events happen, so they learn about how our country is brave. If we stopped these events some people could get hurt worse because when one persons life is saved, it changes history. One life that would have a bad effect is if the person who was saved decided to kill the person who invented the Polio Vaccine. If this happened more people would die of disease, and who knows what that person would do for our next generation. The chain keeps changing history in ways we can never predict.
Changing the world yesterday would have consequences for today, and the many generations to come. One change can effect the other, so to re-do our world can only affect others and how we do things now. It could cause many to be selfish, we would never from what has happened, and it would change the future forever. To me, changing the past is NOT the answer.
