People's lives will be changed by a lot of new things in the future. In the area of medical science, I think cancer will be cured. No one will ever be worried about having cancer any more. In the are of energy, I think there will be new types of energy that is economically feasible and won't pollute our environment. We don't need to use petroleum any more and may be able to use solar power instead. For travelling, there will be more convenient transportation means available. People can travel to the space or go on a vacation in the space. I think robots will be a part of our day-to-day life and they will provide us with all kinds of services.
