The majority of people believe that learning about mistakes from the past is a good help for new generation to stop repeating them again and again. In contrast, some people think the history that we know had changed by so many things in nowadays world.
After all, I totally agree whit this statement even though there are some drawbacks about this fact. Today`s modern world where we are living is the result of the works and experiences that have been done in the past by our ancestors, somethings like mistakes or successes that made current improvements in the world. By learning about things that our ancestors made, the adolescents could make the world a better place to live for all humans to live in. New medications as an example, though there were many mistakes in making new drugs for a particular illness, human beings did exceptional work and experiment for making true consequences with getting help from the previous mistakes and after all, they did it.
On the other hand, some people still believe that there are another effective ways for adolescents to the current world a better place since they think the past can involve new generation with incorrect information. As an example for this belief, teaching that t is true or not from an early age can improve the adolescents ability to make better decisions in any situation. Also gain more knowledge about essential topics can be another helpful way for young people instead of learning about past.
To sum up, I agree that the younger generation could learn about the mistakes and also improvements in the past, but there are also another different ways instead of learning about previous generations.
