How hi-tech and inventions have changed the lives of modern people
Ever since the first man had discovered how to use fire, humans were never looking back in science discoveries, so were more and more advance than all other animals, thus dominating the world. But sicience and technology in the beginning were not just used for humans' benefits and convenience but were mostly used by countries to be more dominant over each others and they still are. You can see how countries all over the world continue to develop more and more hi-tech weapons, creating tentions and fears for many of us and wars are still going on in some parts of the world.
Of course at the same time along the road, non-weapon technologies were also flourishing. Over the centuries, a lot of useful inventions were made to enhance people's everyday life, such as the text, paper, printing, clothes, bulidings just to name a few, and now the modern inventions like car, airplane, train, TV and computers! All of these great things and wonderful inventions have given us plenty of comforts and convenience, making our lives much easier, which also have sparated us from the animals.
Surely all the inventions and hi-tech advancement were made because we humans have not only a better brain but we also know how to use our brains. We have something that all the animals don't. Which is called educatiion. We passed on our knowledge to the next generation. So after many generations, we have accumulated more and more konwledge and thus help us to be even more advance. Nowadays, people can enjoy such wonderful living should thank our generations before us. Without their hard works and sacrifice, we would never be this comfortable. We should consider ourselves are really lucky to be able to live in this era.
