IELTS Reading Passage – Space
Space
Will we find new frontiers or is humanity reaching the end of the universe?
People need to find more creative ways to supply space as populations rise.
A. In his book “An Essay on the Principle of Population,” published in 1798, Thomas Malthus projected that by the mid-1800s, the unregulated rise of the human population would exceed the farmland necessary to feed humanity. A great deal has transpired since then. Since this purported turning point more than 150 years ago, humankind has continued to advance despite being considerably more constrained.
B. Unrestrained population growth is evident. Urbanization is a more visible worldwide phenomenon than ever before as more people migrate from rural areas to cities like Tokyo, Mexico City, and Mumbai in search of a better life. Megacities with more than 10 million inhabitants are cropping up on every continent. Now overpopulated, they are hungry for land. The expanding human population is fueling a voracious need for real estate, despite advances in agricultural technology. Personal, public, corporate, national, human, and flora/fauna space will be at a premium in the next century. They are desperate for one resource that is becoming increasingly valuable: land, and the human population is now at an all-time high. More land is needed for a variety of infrastructure facilities in addition to housing. While advances in agricultural technology mean humanity may be able to feed the people thronging to these huge metropolises, an unparalleled thirst for real estate is being fueled by the growth of the human race. Green pastures are turned into airports, and virgin forests are cleared for food and firewood. In poorer locations, newly exposed land becomes desert, completing the cycle of destruction.
C. The most popular way to utilize pricey space for living and working has been to build upwards; hence, the desire for ever-taller apartments and commercial buildings in big cities like New York, Shanghai, and Singapore. The British Library, which houses millions of books, was built entirely underground—not only for transportation networks but also for garbage storage, book depositories, and more in London. Global construction has become more innovative in recent years. Many countries, including the Netherlands and the UK, have restored marshes and floodplains. Like Venice, Italy, housing complexes and airports have been built offshore. In Japan, Kansai International Airport was built on a man-made island at great expense. In Dubai, a highly inventive and expensive palm tree-shaped housing complex is being developed near the shoreline. Global warming’s rising sea levels threaten these and other developments.
D. But when Earth is at capacity, where will humanity go? Numerous theories have been proposed regarding the expansion of the human population into space. Marshall Savage, for instance, predicted that by the year 3000, there will be five quintillion people living throughout the solar system, with the majority residing in the asteroid belt. Savage’s ardent admirer, Arthur C. Clarke, asserts that humanity will be present on the Moon, Mars, Europa, Ganymede, and Titan, and in orbits around Venus, Neptune, and Pluto by the year 2057. According to Freeman Dyson, the Kuiper belt could become the future home of humanity within a few generations.
E. Huge space stations with human habitation are now a possibility rather than simply a pipe dream. The planet is currently orbited by a permanent multinational space station. Recently, the first commercial tourist visited space, and additional trips are scheduled for the near future. Although this is just the beginning, space hotels are soon to be built. Where humanity may end up is unknown. Though I am sure I am not the only one who fantasizes about spending summer vacations on a floating hotel in the Andromeda nebula or on a distant planet watching the moons rise, the concepts of off-world settlement are not outlandish.
