Skyscrapers

In my opinion, I do not agree to build super high skyscrapers. Although the high skyscrapers can save land and deal with population problem, there are many other problems what the high skyscrapers may cause and have to face. First of all, it is fees of building the high skyscrapers. We can not image how much we should put on it. Merely, the cost of building them is a huge financing, we should consider about other aspects, such as the cost of equipments inside, repairing buildings and so on, we can make sure the high skyscrapers will spend a lot of money. Secondly, emergency has to be paid more attention. For example, if the fire accident happen on the toppest floor, how fast we can solve it, how many workers who will be sent to put out the fire we use...so there are so many new problems we have to face. Last but not least, as an important problem, how can we deal with healthy problems of residenders who live in the high skyscrapers. As we know , health of people has many limits, and different people have different healthy limits. Especially, some people have acrophobia, they can not breath well if they are on the high place, so how they can live in the skyscrapers, it is hard to deal. Do not you think so?
