If present trends continue, the world would face major crises by end of the century: insufficient cheap convenient energy. For without such energy, industrial production will fall, agricultural output will drop, transport will be restricted and standard of living in developed countries will plummet. At present, almost all our energy comes from fossil fuels. The earth’s reserves of fossil fuels have been formed from organic matter subjected to enormous heat and pressure of millions of years. But such reserves are finite. Because power demand is increasing very rapidly, fossil fuels will be exhausted within a relatively short time. We can estimate the amount of recoverable fuel under the surface of the earth and we know the rate at which it is being extracted. Fairly simple calculation can therefore determine its remaining life. If present trends continue, gas and oil reserves will be exhausted by the middle of the 21st century-about 70 years from now. Similar estimates for coal and wood reserves suggest a projected supply of 250-300 years. Of course long before fossil fuels are exhausted, demand will greatly exceed supply.
For too many years, the world has consumed fossil fuels with little thought for the future. In fact, world energy consumption increased almost 600% between 1900 and 1965 and it is projected to increase by another 450% between 1965 and the year 2000. Crude oil has been pumped out of the ground for about 100 years, but over half of it is been consumed in the past 18 years. Coal has been mined for over 800 years, but over a half of it has been extracted in the past 37 years. In sum, most of the world’s consumption of energy from fossil fuels throughout history has taken place within living memory.
The writer warns that the world could Options:In 1951, the Government decided to start a Pottery Training Centre where new and more advantaged technical methods, especially glazing, could be taught. The centre was intended to serve the whole of the defunct Northern Region, and there were several reasons for choosing Abuja . The first was the excellence of the traditional pottery made in the Emirate. Secondly, firewood is plentiful; this is a most important consideration, because in the making of glazed pottery, more firewood than clay is required. Thirdly, there are good clays, and good local sources for the raw materials needed for the glazes. Fourthly, water, which is another important raw material, is plentiful. Finally, Abuja is in a central position for the whole region and is a town where learners from many different parts can find a congenial temporary home, and where the Emir and his Council are actively interested in the project.
Nearly all the making is done by a process called throwing;, so called because the lumps of clay are thrown the potter onto a wheel-head. They are weigh out so that each pot will be roughly the same size; for example, for making pint-sized jugs, the lumps of clay will be one and a half kilogrammes. The potter sits on the saddle of the wheel and spins it by pushing a pedal with his left foot. He has a bowl of water, a loofah, a bamboo knife, a pointed stick or porcupine quill, a wooden-smoothing tool which potters call a rib, and a piece of wire-like object that is used for wedging. He makes the wheel-heal slightly damp, and throws the lumps into the middle. The first work is to force the lump to the centre, then he presses his thumb into the middle of the lump, using water to keep it slippery. When the bottom is of the right thickness, he begins to draw up the walls until they are of the right height. Then he shapes the belly and shoulder of the pot. He trims off any waste clay. In this way, a small and medium-sized pot can be made quickly and accurately.
