'Building sickness - sick building syndrome', depression, polluting, noise, illness in general. Why do we live in city's? Most of the people come to a city because of our moneysystem. They need money to live. Rent, ground prices, to low prices to agriculture products make that people come to cities. So we made our own problem. City's aren't made to hold such a big amound of people. They only come for the money. So we have to change the moneysystem to get a more healthy situation. Lower the prices for houses for eample and give people the free space and the food to live.
