Cities of the future. The population of the Earth is increased from year to year. And our cities become wider and take more area around. More quantity of people produce more garbage and use more vehicle recently. So, there are some problems in future, such as reducing free area for living, ecology aspects and cutting the energy resources. This is that we need to solve and change our cities and lifestyle. The first problem is the area for living. Nowadays there are a lot of modern tall buildings, such as sky towers. And this is the first step to decide the problems. And such buildings are not only for offices or apartments, but for parking and green zones. Also in future we can use the space of oceans, designing special platforms for living and growing the vegetables and fruit, or use areas on The Far North making the constant climatic zone with using the space technology. I don't imagine that the humanity will live underground, but I can not deny that it is possible. The second problem is ecology. Smog and garbage is the main items that need to be solved. We need to reduce using the gasoline. For example, to use only a public transport, to make bicycles public, to use electromibles or to find the other fuel for vehicles. Or even to manage the business on distance not leaving the home, but use modern devices, such as video cams and video calls. Also we must to begin sorting the garbage and then recycle it. To decide the catastrophe of plastic trash, we need find organic replacement of this material. And the last item is energy resources. The cities of future must be provided by electricity. And the solar panels and windmills are that we need to develop. I suppose that we will find some other origin of energy, from the bowels of the earth, for example. As for me I don't see the crucial difference between modern cities and the cities of future. Maybe there will be more space technologies that we will introduce to daily life in future.
