Will the world’s future population, upon hitting the 9 or 10 billion mark, be able to enjoy a prosperous lifestyle complete with high-tech conveniences, spacious living environments, and high-speed transit without destroying the global ecosystem? Challenging the pessimistic view that humanity is doomed to endure perpetual poverty or regress to a primitive lifestyle to save the Earth, the reading passage Worldly Wealth presents an optimistic perspective driven by the power of technological progress: from material recycling, alternative energy, agricultural productivity breakthroughs that return natural land to the wild, lab-grown meat, to autonomous flying vehicles.

Centering on the themes of futurology, environmental science, and sustainable economics, the passage features sharp critical argumentation alongside highly inferential questions. The test evaluates candidates across three primary question types: Yes/No/Not Given, Summary Completion, and Multiple Choice. The comprehensive answer breakdown, academic vocabulary glossary, and full translation below will help you fully master this reading text.

Reading Passage

Worldly Wealth

Can the future population of the world enjoy a comfortable lifestyle, with possessions, space and mobility, without crippling the environment?

[Paragraph 1] The world’s population is expected to stabilize at around nine billion. Will it be possible for nine billion people to have the lifestyle enjoyed today only by the wealthy? One school of thought says no: not only should the majority of the world’s people resign themselves to poverty forever, but rich nations must also revert to simpler lifestyles in order to save the planet.

 

[Paragraph 2] Admittedly, there may be political or social barriers to achieving a rich world. But in fact there seems to be no insuperable physical or ecological reason why nine billion people should not achieve a comfortable lifestyle, using technology only slightly more advanced than that which we now possess. In thinking about the future of civilization, we ought to start by asking what people want. The evidence demonstrates that as people get richer they want a greater range of personal technology, they want lots of room (preferably near or in natural surroundings) and they want greater speed in travel. More possessions, more space, more mobility.

 

[Paragraph 3] In the developed world, the personal technologies of the wealthy, including telephones, washing machines and cars, have become necessities within a generation or two. Increasing productivity that results in decreasing costs for such goods has been responsible for the greatest gains in the standard of living, and there is every reason to believe that this will continue.

 

[Paragraph 4] As affluence grows, the amount of energy and raw materials used for production of machinery will therefore escalate. But this need not mean an end to the machine age. Rather than being thrown away, materials from old machinery can be recycled by manufacturers. And long before all fossil fuels are exhausted, their rising prices may compel industrial society not only to become more energy efficient but also to find alternative energy sources sufficient for the demands of an advanced technological civilization: nuclear fission, nuclear fusion, solar energy, chemical photosynthesis, geothermal, biomass or some yet unknown source of energy.

 

[Paragraph 5] The growth of cities and suburbs is often seen as a threat to the environment. However, in fact the increasing amount of land consumed by agriculture is a far greater danger than urban sprawl. Stopping the growth of farms is the best way to preserve many of the world’s remaining wild areas. But is a dramatic downsizing of farmland possible? Thanks to the growth of agricultural productivity, reforestation and ‘re-wilding’ has been under way in the industrial countries for generations. Since 1950 more land in the US has been set aside in parks than has been occupied by urban and suburban growth. And much of what was farmland in the nineteenth century is now forest again. Taking the best Iowa maize growers as the norm for world food productivity, it has been calculated that less than a tenth of present cropland could support a population of 10 billion.

 

[Paragraph 6] In The Environment Game, a vision of a utopia that would be at once high-tech and environmentalist, Nigel Calder suggested that ‘nourishing but unpalatable primary food produced by industrial techniques – like yeast from petroleum – may be fed to animals, so that we can continue to eat our customary meat, eggs, milk, butter, and cheese and so that people in underdeveloped countries can have adequate supplies of animal protein for the first time.’

 

[Paragraph 7] In the long run, tissue-cloning techniques could be used to grow desired portions of meat by themselves. Once their DNA has been extracted to create cow-less steaks and chicken-less drumsticks, domesticated species of livestock, bred for millennia to be stupid or to have grotesquely enhanced traits, should be allowed to become extinct, except for a few specimens in zoos. However, game such as wild deer, rabbits and wild ducks will be ever more abundant as farms revert to wilderness, so this could supplement the laboratory-grown meat in the diets of tomorrow’s affluent.

 

[Paragraph 8] With rising personal incomes come rising expectations of mobility. This is another luxury of today’s rich that could become a necessity of tomorrow’s global population – particularly if its members choose to live widely dispersed in a post-agrarian wilderness. In his recent book Free Flight, James Fallows, a pilot as well as a writer, describes serious attempts by both state and private entrepreneurs in the USA to promote an ‘air taxi’ system within the price range of today’s middle class and perhaps tomorrow’s global population.

 

[Paragraph 9] Two of the chief obstacles to the science fiction fantasy of the personal plane or hover car are price and danger. While technological improvements are driving prices down, piloting an aircraft in three dimensions is still more difficult than driving a car in two, and pilot error causes more fatalities than driver error. But before long our aircraft and cars will be piloted by computers which are never tired or stressed.

 

[Paragraph 10] So perhaps there are some grounds for optimism when viewing the future of civilization. With the help of technology, and without putting serious strains on the global environment, possessions, space and mobility can be achieved for all the projected population of the world.
