UNIT 6 RESOURCE SAVING
Assignment 1
Everybody knows that there are such natural resources as minerals, energy, land, water and biota. Take a look at the following pictures displaying natural resources (A-E) and match them with the names.
A______________ B______________ C______________
D______________ E______________
Assignment 2
Scan the article and find answers for the questions.
1. How many Earth’s resources do people consume nowadays? What are they?
2. What is the result of this consumption?
3. What are the most reasonable ways of solving the problem of ravening resources?
Earth suffers as we gobble up resources
ALMOST one-quarter of nature's resources are being gobbled up by a single species, and it's not difficult to guess which one. Based on figures for the year 2000, the most recent available, humans appropriate 24 per cent of the Earth's production capacity that would otherwise have gone to nature.
The result is a gradual depletion of species and habitats as we take more of their resources for ourselves. Things could get even worse if we grow more plants like palm oil and rapeseed for biofuels to ease our reliance on fossil fuels.
That is the message from a team led by Helmut Haberl of Klagenfurt University in Vienna, Austria. Haberl and colleagues analysed UN Food and Agriculture Organization data on agricultural land use in 161 countries covering 97,4 per cent of farmland. By comparing carbon consumption through human activity with the amount of carbon consumed overall, Haberl's team found that humans use some 15.6 trillion kilograms of carbon annually. Half was soaked up by growing crops. Another 7 per cent went up in smoke as fires lit by humans, and the rest was used up in a variety of other ways "Things could get even worse if we grow more plants like palm oil and rapeseed for biofuels to ease our reliance on fossil fuels" related to industrialisation, such as transport [Proceedings of the National Academy of Sciences].
Haberl says that the Earth can just about cope if we meet future needs by producing food more efficiently. This could be done by intensifying agriculture on roughly the same amount of land as we use now. But we're asking for trouble, he says, if we expand production of biofuels, as the only fertile land available is tropical rainforests.
"If we want full-scale replacement of fossil fuels by biofuels, this would have dramatic implications for ecosystems," says Haberl. He warns that some projections foresee four or fivefold increases in biofuel production. "This would at least double the overall amount of biomass harvested, which is about 30 per cent above ground at present, but would increase to 40 or 50 per cent to meet these biofuel targets," he says.
This would mean clearing what remains of the world's rainforests in countries such as Brazil and Argentina. As well as wiping out thousands of species, this would have devastating effects on the climate, he says. Unlike farmland, forests help to seed rainfall because they have high evaporation rates.
"The less evaporation there is, the less rainfall there is and the whole system dries up," he says. Andy Coghlan

valuable, petroleum extraction, renewable, coal, tax on consumption, raw materials, natural, forestry, fossil fuels, natural gas
Natural resources (economically referred to as land or 1______________) are naturally forming substances that are considered 2______________in their relatively unmodified (3_____________) form. Thus, mining, 4_____________, fishing, hunting and 5_____________ are generally considered natural-resource industries.
Natural resources are mostly classified into 6______________ and non-renewable resources. Sometimes resources are classified as non-renewable even if they are technically renewable, just not easily renewed within a reasonable amount of time, such as 7_____________.
Some non-renewable resources can be renewable but take an extremely long time to renew. Fossil fuels, for example, take millions of years to form and so are not practically considered 'renewable'. Different non-renewable resources like oil, 8_____________, 9_____________ etc. have different levels of demand from different sectors like transportation and residences with each resource specializing for each sector. Many environmentalists propose a 10_______________ of non renewable resources. Non-renewable resources cannot be replaced or can only be replaced over thousands or millions of years.
Assignment 5
Use the words given in capitals to fulfill the spaces.
Resource Saving
Resources are limited and we need to handle them 1_____________ and responsibly. New resource saving potential along the textile value-chain is worth 2_______________. The environmental impact of textile production is 3_______________ due to the vast quantity of water required and the variety of chemicals used that generates wastes. BASF offers 4______________ that bring the same desired effect using fewer amounts of chemicals. Moreover, solutions that increase the 5______________ of a process can result in saving water and energy, as well as time and costs.
Global 6______________ is becoming increasingly fierce, while at the same time the textile industry is confronted with ever 7______________ environmental standards and regulation. 8_______________ is definitely the key driving force leading the textile industry towards a stronger future. Yet for long-term success one must meet the growing demand for eco-efficient solutions. Only those who meet both environmental and economic challenges remain 9_______________. Eco-efficiency means how environmentally 10_______________ and economic a product or process is. At BASF, we call such products or processes that meet both environmental and economical requirements “eco-efficient” solutions. COMPETITIVE
