It 37 38 AGRICULTURAL AND URBAN AREAS is not really a modern invention; it was used by the Romans in the building of their aqueducts and amphitheaters. The Romans used slaves to handle large concrete blocks, but with the development of lifting machinery and cranes we can now build from concrete without using slaves. It is now possible to cast concrete into large slabs and to raise them into position using cranes so that the construction of large buildings can proceed very rapidly. This movement away from the use of local rocks in building has led to cities around the world becoming more uniform in their design and their construction materials.

It can be seen that the side of the hedge facing the sea has a much heavier load of salt than the lee side, which is protected from the wind. About 80 percent of salt deposition occurs on the windward side, a fact that shows how effectively the hedge is acting as a filter. In pastoral systems the height of the vegetation has a considerable influence on the microclimate near the ground. Tall grasses act rather like small forests; they reduce light penetration and wind speed so that the climate at the soil surface has lower light intensity, is more stable in its temperature, and is more humid than the air above the canopy.

Many primates also build such nests, as do invertebrates like ants and termites. All of these animals are seeking to modify their own microclimate to suit their own needs. Humans have the advantage of a high brain capacity and the ability to innovate in their constructions of dwellings, depending on the local circumstances. Where wood was not available, mud bricks could be made and built into complex structures. If caves were not available, then artificial caves could be constructed using stones or turf cut from the soil.
