Income as affected by climatic conditions

1. The bounty and variety of the natural supply of indirect goods in the material world are the prime conditions of a bountiful income to society. The effect of climate on the supply of goods available for man is complex. Climate is itself a direct source of gratification. As temperature must be adjusted to man's need, climate satisfies wants directly. Health, energy, the beauty of noonday woods and of sunlit clouds are conditioned on the favor of nature. Climate affects, further, the supply of material economic goods. All the earlier civilizations arose in warmer countries. But, after man had gained a certain mastery over the obstacles of nature, he was able to soften the harsher features of climate, and with better shelter and clothing, with better stocks of winter food and fuel, the more favorable features of the temperate zone could be utilized. So civilization moved northward from Egypt and India to Greece and Rome, to northern Europe and America.

By natural resources

Soil conditions for vegetable life determine first the amount and kind of animal life. Animal life from one point of view is a parasite, living on the vegetable; it is only the vegetable that has power to assimilate most inorganic compounds. Water being a need of plant life, the amount of rainfall is one of the most important conditions of industry. Man, therefore, depends on the resources of the soil directly or indirectly; a fertile soil furnishes him either directly a supply of vegetable food, or indirectly a supply of animal food.

Natural supplies of metals, of coal, and of timber are important consumption goods, but they are also indirectly the condition for a vast variety of other goods. The industry that could exist without iron, copper, and coal would be of a very low grade.

By flora and fauna

The variety of flora and fauna, and their fitness for man's needs, largely condition the possible production. If, in the course of evolution, it had chanced that wheat and corn, the horse and the cow, had been crowded out in the struggle for existence, we should have had a very different civilization. The possibilities of civilization in Peru, and those of all the Indians on the American continent, were limited for lack of domestic animals. Animals that are fit for domestication are a necessary intermediate agent by aid of which man can appropriate and turn to his use the fertile qualities of the soil.

Not content with the material world about him, even when it is at its best, man alters it in many ways. He enriches the soil, improves the varieties of animals, he even in some slight degree affects the climate, and by the use of a multitude of artificial bits of matter called tools, works profound changes in the world in which he lives.

By motion and energy

2. A large part of the utility of goods is conditioned on motion and energy. It has been said that man's power in production is limited to moving things. The outer world is to man the sole source of motive forces. He can bring things together and they produce the result. Further, it may be said that nearly every kind of utility is conditioned on motion. It is man's aim to secure a constant inflow of goods. To secure this either he must move to get the goods, or he must cause goods to move toward him.

The law of "conservation of energy" helps to explain economic action; the supply of energy in the universe cannot be increased or diminished, but may take on new forms. So a limited supply in man's control may take on various forms and so have different effects on gratifications. One and the same source of energy may be converted into the different forms of heat, light, motion, electricity, etc. But there must be some source. Man's desire is directed to getting force at the right place and in the right degree. If light or heat is too intense, it causes pain; the glare of the sun blinds instead of giving keener vision. A moderate force applied to any of the senses gives the maximum clearness or pleasure. Man is constantly endeavoring to secure forces from the outer world and to adjust motion so that it will directly or indirectly best serve his purposes.

By food, animals, and fuel

3. Among the main sources of power used by men are food, domestic animals, and fuel. In eating food man stores up force in his own body. When he draws the bow he puts force into it to lie latent until liberated at the right moment. There must be a source of energy likewise that mental action may go on, and the power of sunbeams, stored for a time in food, is liberated in the processes of thought.

This first natural mode of liberating energy within their own bodies does not satisfy the growing needs and aims of men. Such a mode is "labor," which becomes at times painful and distasteful. In the earliest societies known, some sorts of domestic animals are found supplementing man's efforts and acting upon the material world to alter it for man. The dog joining in the chase guards his master's safety, and helps to bear his burdens. The draft-beast in the field turns the heavy soil, and aids in the final harvest. The trained elephant does the work of twenty men piling logs, loading ships, or carrying burdens.

Man further increases his control over the material world by making other men do his bidding. Domestic slavery, where wife or child serves the father of the family, or chattel slavery, where the vanquished toils for the victor, are all but universal in early communities. Such a method of increasing one's control over the forces of the world requires only superior strength, no special intelligence in mechanics, and is thus one of the first crude devices in a primitive civilization.

Fuel has been, up to the present time, perhaps the most important source of energy. Fire in the hands of savage man gave him dominion over the forests and over the metals. In this age of steam the liberation of the energy of the sun, stored up in coal in ages past, is still the indispensable condition of our developed industry.

By the energy in wind and flowing water

4. The greatest and most exhaustless reservoirs of power for man's use are in wind and water. While the supply of fuel is being used at a progressive rate and will soon approach exhaustion, there are elsewhere exhaustless stores of energy awaiting man's command. To make use of the wind for sailing a boat, only the simplest arrangements are needed; a windmill fixed at one place requires more ingenuity and machinery. The energy of the wind is derived from the sun and will last until the sun loses its heat. If some means can be found for equalizing the flow and for storing the power of the wind, it may yet become a great agency of industry. The force of falling water, long used in a petty way by the old water-mills, is just beginning to be employed on a large scale at such points as Niagara. Where fuel is high, as on the Pacific coast, wave motors have been successfully used in a small way, but wave motion is too irregular to serve well the needs for power. But the constant motion of the tides offers, at some favored points, a source of power that will remain as long as the earth revolves upon its axis.

By the intelligent utilization of all these agencies

5. Man studies and compares the durable goods that give him command over enjoyable goods, and attaches value to them. Thus energy is found dissipating itself throughout the world in ways useless to man, and in places where it cannot serve his purposes. As man grows in power of control over nature, he seeks to apply these forces in forms and at places he has selected. If he can arm himself with the energies of mine and torrent, he can react with giant strength on the material world. He ceases to accept passively its conditions, and to live on its grudging gifts; he becomes its fashioner, in a sense its creator. His intelligence and his wants are most important factors determining what the form of the physical world about him shall be.

But all the efforts of men in the most developed economy cannot make to disappear the differences in the quality of goods and agents. Desirable goods to consume are limited in quantity, and they vary in quality; hence they have value and some higher than others. Likewise, durable material agents and sources of power are limited in number and vary in convenience of location and efficiency. As men seek to gratify their desires, they attach importance to these agents of power. Each is valued for its service or its series of services. When anything is seen to contain a series of uses, it becomes a rent-bearer, and the economic problem of rent arises, one step more complex than the problem of valuing simple consumption goods.
