Mr.Brown’s presentation informed us that it is important to learn history. It is important to acquire a knowledge of history because back then, they found a way to reduce similar problems that we face today. In my opinion, even though this generation has invented ways to reduce the negatives, I feel like they do not know the consequences that comes with it. Also, I feel like they just build objects immediately thinking its good for everything, instead of taking a step back, to see what they can do to make a better place. Yet, long time ago, people already found a way to make the world a much better place, without using ANY technology, which means by using their ideas and techniques we can build a better world without any harm. Mr. Brown’s presentation made us notice that and much more, using Japan as an example, to demonstrate what types of techniques they used long time ago to reduce what they use and to make their village a easier place to live.
