We wouldn't be surviving if science hadn't brought us to knowing what chemicals and elements weresamd and which would kill us. Our powerful NASA Space Division wouldn't be real. We wouldn't be wondering who would be the first person on Mars. No one would care about reaching extraterrestrial life forms on other planets. This is why science is important.
Science is important because of all the new technology which has improved many inventions and ideas.
Another reason science is important is because people need to know how the world works and how things in it effect our lives and future. Also it is important because the scientific thoughts have interpreted and helped people's lives. In science we learn about different kinds of animals and where they live. We learn about plants, how grow and how long it takes for them to grow. Science is important because we learn about the food chain.
