Text 2 When enthusiasts talk of sustainable development, the eyes of most people glaze over. There is a whiff of sack-cloth and ashes about their arguments, which usually depend on people giving up the comforts of a modern economy to achieve some debatable greater good. Yet there is a serious point at issue. Modern industry pollutes, and it also seems to cause significant changes to the climate. What is needed is an industry that delivers the benefits without the costs. And the glimmerings of just such an industry can now be discerned. That industry is based on biotechnology. At the moment, biotech’s main uses are in medicine and agriculture. But its biggest long-term impact may be industrial. Here, it will diminish demand for oil by taking the cheapest raw materials imaginable, carbon dioxide and water, and using them to make fuel and plastics. Plastics and fuels made in this way would have several advantages. They could accurately be called "renewables", since nothing is depleted to make them. They would be part of the natural carbon cycle, borrowing that element from the atmosphere for a few months, and returning it when they were burned or dumped. That means they could not possibly contribute to global warming. And they would be environmentally friendly in other ways. Bioplastics are biodegradable, since bacteria understand their chemistry and can therefore digest them. Biofuels, while not quite "zero emission" from the exhaust pipe (though a lot cleaner than petrol and diesel), would be cleaner overall even than the fuel-cell technology now being touted as an alternative to the internal-combustion engine. That is because making the hydrogen that fuel cells use is not an environmentally friendly process, and never will be—un less it, too, uses biotechnology. All this will, in the end, depend on costs. But these do not look unfavourable. Already, the price of bioplastics overlaps the top end of the petroleum-based plastics market. Bulk production should bring prices ’down, particularly when the raw materials are free. Meanwhile, ethanol would be a lot easier to introduce than fuel cells. Existing engines will run on it with minor tweaking, so there is no need to change the way ears am made. And since, unlike hydrogen, it is a liquid, the fuel-distribution infrastructure would not need radical change. The future could be green in ways that traditional environmentalists had not expected. Whether they will embrace that possibility, or stick to sack-cloth, remains to be seen.

Australia is nearly as large as the United States, but most of it is too dry for people to live in. Around this dry part are large sheep and cow farms. A few of them are as large as the smallest states in America. Often the nearest neighbours are several hundred kilometers away. The two-way radio is very important to people who live on these great Australian farms. It works much like a telephone. A person can listen to someone else talk and then give an answer. For example, people on the large farms could talk to a doctor far away. They could tell the doctor about someone who was ill, and the doctor could let them know how to look after the sick person. As the large farms were so far from towns, the children could not go to school. Radio schools were started for them in some places. At a certain time each day, boys and girls turn on their radios and listen to teachers in cities far away. Families on the large farms wanted to give news to their neighbours. The programme "Round Robin Talks" by radio was started to keep families in touch with each other. They could talk about who was going away and who was ill. The men could talk about their sheep and cows and how much money the markets would pay for them. In many ways the radio became a newspaper for the farm people of Australia.
