ssary that every lecture or every book about this subject has to start with the proof of this idea. (111) At present it is generally accepted, although more as a self-evident statement than on the basis of a closely-reasoned scientific proof. The recognition of the importance of greenery in the urban environment is a first step on the right way. (112) This does not mean, however, that sufficient details are known about the functions of greenery in towns and about the way in which the inhabitants are using these spaces.As to this rather complex subject I shall, within the scope of this lecture, enter into one aspect only, namely the recreative function of parks.

(113) The theoretical separation of living, working traffic and recreation which for many years has been used in town-and-country planning, has in my opinion resulted in disproportionate attention for forms of recreation far from home, whereas there has been relatively little attention for improvement of recreative possibilities in the direct neighborhood of the home. (114) We have come to the conclusion that this is not right, because an important part of the time which we do not pass in sleeping or working is used for activities at and around home. So it is obvious that recreation in the open air has to begin at the front door of the house.

(115) The urban environment has to offer as many recreation activities as possible, and the design of these has to be such that more obligatory activities can also have a recreative aspect. The very best standard of living is nothing if it is not possible to take a pleasant walk in the district; if the children cannot be allowed to play in the streets, because the risks of traffic are too great; if during shopping you can nowhere find a spot for enjoying for a moment the nice weather; in short, if you only feel yourself at home after the front door of your house is closed behind you.

tretches of land are dropping precipitously. Whole river systems have dried up. Others are chocked with sediment washed from denuded land. 21.Hundreds of thousands of acres of previously irrigated cropland have been abandoned to wind or weeds. Several million acres of natural grassland are eroding at unnaturally high rates as a result of cultivation or overgrazing. All told, about 225 million acres of land are undergoing severe desertification.

22.Federal subsidies encourage the exploitation of arid land resources. Low-interest loans for irrigation and other water delivery systems encourage farmers, industry, and municipalities to mine groundwater. Federal disaster relief and commodity programs encourage arid-land farmers to plow up natural grassland to plant crops such as wheat and, especially cotton. Federal grazing fees that are well below the free market price encourage overgrazing of the commons.The market, too, provides powerful incentives to exploit arid land resources beyond their carrying capacity. 23.When commodity prices are high relative to the farmer's or rancher's operating costs, the return on a production-enhancing investment is invaribly greater than the return on a conservation investment. And when commodity prices are relatively low, arid land ranchers and farmers often have to use all their available financial resources to stay solvent.

24.If the United States is, as it appears, well on its way toward overdrawing the arid land resources, then the policy choice is simply to pay now for the appropriate remedies or pay far more later, when productive benefits from arid land resources have been both realized and largely terminated.

an assist other people. What we cannot do is make what we do for others or what others do for us more important than what we do for ourselves.
