Write a Précis of the following passage and suggest a title:
Climate influences labour not only by enervating the labourer or by invigorating him, but also by the effect it produces on the regularity of his habits. Thus, we find that no people living in a very northern latitude have ever possessed that steady and unflinching industry for which the inhabitants of temperate regions are remarkable. In the more northern countries the severity of the weather, and, at some seasons, the deficiency of light, render it impossible for the people to continue their usual out-of-door employments. The result is that the working classes, being compelled to cease from their ordinary, pursuits, are rendered move prone to desultory habits, the chain of their industry is, as it were, broken, and they lose that impetus which long continued and uninterrupted practice never fails to give. Hence there arises a national character more fitful and capricious than that possessed by a people whose climate permits the regular exercise of their ordinary industry. Indeed, so powerful is this principle that we perceive its operations even under the most opposite circumstances. It would be difficult to conceive a greater difference in government, laws, religion, and manners, than that which distinguishes Sweden and Norway, on the one hand, from Spain and Portugal on the other. But these four countries have one great point in common. In all of them continued agricultural industry is impracticable. In the two Southern countries labour is interrupted by the dryness of the weather and by the consequent state of the soil. In the northern countries the same effect is produced by the severity of the winter and the shortness of the days. The consequence is that these four nations, though so different in other respects, are all remarkable for a certain instability and fickleness of character.
Precis:
The habits of the working class are, for the most part, shaped by the climate. The economies of the northern countries significantly differ from those of the southern and temperate countries. The intensity of the coldness and hotness in northern and southern countries confines people to indoor activities and infuses them with vacillating characteristics. This restricted environment instils in them the habits of cursory and half-hearted activities that are quite opposite to those of the denizens of the temperate regions of the globe. Resultantly, the environment shapes the national character, policies, and principles of people living in different zones of climate.
