To some people, human beings would extinct during one moment. If only one person survives on the earth, definitely he or she would become a nut and choose to attempte suicide. That is not a very responsible way. To me, if I were the only man on the earth, I would make the earth more advanced compared to this society.
First, I would make use the technology of the human beings today to clone myself. So, there is another person, beside me on the earth. So, we can communicate with one another to get some ideas about something, apart from having some pleasures. Then, that person would clone himself and this incident is repeated again and again. Yes, we are having the same characteristic and easy to make friends.
Then, the technology is used again to train wild animals on how to communicate and understand one another. These animals are also being trained to be nice to one another. So, there is no accident happens when communicating with them. To increase the population of the animals, taking care of their habitat is important. For example, planting more trees in a forest that is protected. These animals are useful for us in leading a hand when doing some projects or chores. We are also used to respect each other so that the connection between clones and animals can be improved.
For the construction, underwater and land construction are required. For land construction, clones are helped by strong animals such as rhinos, buffalos and elephants. These animals are used to carry heavy loads for construction and advanced technology is used by clones to fix the building. Then, underwater construction is helped by whales and dolphins. These buildings are not polluting the environment and its design is special and suitable for the surroundings.
Apart from that, the security there is also stern. Including land, water and air. For land, clone polices are helped by wolves, tigers and cheetahs. For underwater, the usage of seal, barracudas and sharks is attached importance. For air, eagles and hawks are also paid attention too. The polices are armed with deadly weapons and developed equipments depend on the surroundings.
There, more scientists are trained and used for our better lifestyle. Our clothes are different as special equipments are used. Our discipline is also important in our daily life. Recycling transport are used as it save the environment with the usage of solar energy. It is also fast too to go to a destination we want.
That are what I would do if I were the only man on the earth.
