PATTERNS OF RESOURCE CONSUMPTION TYPES OF RESOURCES Natural Resources : Anything in the biophysical environment that can be used by people; i.e. a naturally occuring material that a society perceives as being useful to its economic and/or social well-being, and which can be used or exploited. Renewable Resources: Are those materials that can be regenerated in nature faster than they are being exploited by a society. E.g.: Solar radiation, water, wind, soil, plants and animals. Non-renewable Resources: Is a material generated slowly in nature that, for all practical purposes, it exists in a finite quantity. Examples include all fossil fuels (coal, natural gas and oil), minerals (metallic and non-metallic), and nuclear fuels (like uranium, plutonium etc). RECYCLING NON-RENEWABLE RESOURCES Many non-renewable resources can be recycled, which means they can be used repeatedly. Examples include most metals (such as aluminum, lead and zinc); some nonmetallic minerals (like diamonds) and materials manufactured from fossil fuels (such as plastics). OTHER WAYS OF CLASSIFYING RESOURCES ENERGY RESOURCES (fossil fuels, geothermal reserves, water [used for hydro-electricity], radioactive material; ORGANIC RESOURCES (soils, forests, animals) WATER RESOURCES LANDSCAPE NEO-MALTHUSIANS VS. ANTI-MALTHUSIANS NEO-MALTHUSIANS: - Non-renewable resources are finite and therefore exhaustible (e.g. Paul Ehrlich); - A combination of population growth and finite natural resources will create mass misery (Club of Rome) ANTI-MALTHUSIANS: - Price is what determines scarcity, not the physical quantity of a resource (Julian Simon) - If something is becoming scarcer, its price will increase (Demand and Offer Law of Economics) - Over time, the price of every natural resource tends to decrease; thus, they become more abundant (less scarce). ANTI-MALTHUSIANS A) Boserupians: It was first developed by Danish economist Ester Boserup in 1965 as a counterpart to both the malthusian and neomalthusian theories. Boserup's idea was a challenge to the assumption dating back to Malthus’s time (and still held in many quarters) that agricultural methods determine population (via food supply). Instead, Boserup argued that population determines agricultural methods. A major point of her book is that "necessity is the mother of invention". It was her great belief that humanity would always find a way and was quoted in saying "The power of ingenuity would always outmatch that of demand"; Although Boserup's original theory was highly simplified and generalized, it proved instrumental in understanding agricultural patterns in developing countries. By 1978, her theory of agricultural change began to be reframed as a more generalized theory. The field continued to mature in to relation to population and environmental studies in developing countries B) Reformists: Many scholars – economists and geographers and demographers – from developing nations elaborated this theory based on Boserup's studies. Like the boserupian theory, the Reformist theory was a response to Neomalthusians. But the focus was not agricultural production – as was Boserup's – but instead, economic development. Reformists believe that countries aren't poor because they are populous (like Malthus' original idea, and neomalthusians), but, on the contrary, that countries are populous because they are poor. Once countries get richer, its population starts to shrink naturally. It is the theory – along with Boserupian – that has proved to be closer to reality. C) Limits-to-Growth/Club of Rome: “The Limits to Growth” is a 1972 book about the computer simulation of exponential economic and population growth with finite resource supplies.Funded by the Volkswagen Foundation and commissioned by the Club of Rome it was first presented at theSt. Gallen Symposium. Its authors were Donella H. Meadows, Dennis L. Meadows, Jørgen Randers, and William W. Behrens III. The book used the World3 model to simulate the consequence of interactions between the Earth's and human systems. Five variables were examined in the original model. These variables are: world population, industrialization, pollution, food production, and resource depletion. The authors intended to explore the possibility of a sustainable feedback pattern that would be achieved by altering growth trends among the five variables under three scenarios. They noted that their projections for the values of the variables in each scenario were predictions "only in the most limited sense of the word," and were only indications of the system's behavioral tendencies.Two of the scenarios saw "overshoot and collapse" of the global system by the mid to latter part of the 21st century, while a third scenario resulted in a "stabilized world.“ D) Marxists: Karl Marx was contrary to Malthus's views on population growth. According to Marx, population increase must be interpreted in the context of the capitalistic economic system. A capitalist gives to labor as wage a small share of labor's productivity, and the capitalist himself takes the lion's share. The capitalist introduces more and more machinery and thus increases the surplus value of labor's productivity, which is pocketed by the capitalist. The surplus is the difference between labor's productivity and the wage level. A worker is paid less than the value of his productivity. When machinery is introduced, unemployment increases and, consequently, a reserve army of labor is created. Under these situations, the wage level goes down further, the poor parents cannot properly rear their children and a large part of the population becomes virtually surplus. Poverty, hunger and other social ills are the result of socially unjust practices associated with capitalism. Thus, Population growth, according to Marx, is therefore not related to the alleged ignorance or moral inferiority of the poor, but is a consequence of the capitalist economic system. MALTHUSIANS VS.
