From horses to rockets, the world has changed a lot. With science ideas, and innovation, life have been made easier. Long ago, people used horses to move from one place to another. That was the major means of transportation. The horses were strong and fast compared to walking with legs and they helped people travel and carry goods.
As time goes by, people started thinking of how to improve life more better. They wanted better ways to move and they began to use their brains to make new things. They looked at how things work and tried new ideas. After some time, the bicycle was created. It was faster than walking and did not need food like a horse. You just needed to pedal. Bicycle made life little easier but still people needed more better means of transporting themselves.
The horses get tired after riding it for some time, like wise the bicycle, the legs of people riding it get tired and weak. So there was need for a new innovation.
With time, people were able to invent something even bigger, the car. When the first cars were made, they looked strange people, imaging machine with four legs(wheels) like the horse and made a lot of noise. People were not sure they would work. But slowly there was an improvement in the engines and people started to like them. It became the better means of transportation. Cars could go farther and faster than horses or bicycles. And also didn’t get tired. Over time, cars became better, faster, and more affordable and comfortable for people.
Science kept growing and people wanted to go even faster in movement. And as time goes by, trains were invented. Trains could carry many people and much goods at once and ar even more faster. They were big and strong and moved on tracks. After the trains, buses and trucks came along too.
Science kept on growing and people wanted to move beyond the ground to flying in the air like a bird. This led to the invention of the airplane. At first, the idea of flying like a bird sounded like a joke to some people and a dream to others. How can people fly like birds? Science made it happen. People could now fly in the sky and reach far places in just a few hours instead of days when using the cars or buses. The airplanes changed the way the world moved and break the limit with which people can travel from country to country. Cars, trains, buses cannot go to some countries because of the obstacles like seas, oceans that separates them but the airplanes can fly over those obstacles. Today, you can fly from one country to another in just a few hours.
But the biggest leap came when humans started looking at the stars and the moon. Rockets were created. They can leave the earth and go into space within seconds or minutes. Today, rockets are used to send satellites into space. Some rockets carry machines to explore other planets like Mars. Some even carry people into space.
From riding horses on land to walking on the moon, science made it all possible. Science is still growing and soon, people might even visit other planets like we visit other countries today and may even live there. New things are being made every day. One day, we might have flying cars all over us like the normal cars we see now and we may even experience the same traffic we are experiencing now on the road in air, who knows?
In as much as those innovative and transformations are good we should not neglect the negative out come of where science could take us. In the case of this horse to rockets transformation, most of those machines releases smoke and gases into the air, which has made the environment dirty and added to the climate change issues we are facing today. Also most of those rockets leave behind space junks of broken parts in space causing those junks to float around in space and causing damage to some satellite and lot more consequences.
