Water, Water Everywhere
Approximately 70 percent of our planet is covered in water. In total, that’s approximately 1,260 million trillion liters, which sounds like an enormous amount, but less than one percent of it can easily be used as drinking water. A major amount, 97 percent, is salt water, and two percent is glacier ice. Scientists and politicians are becoming increasingly worried about the amount of water, and predict that there will be wars in the future to control our water supplies.
The world’s population is growing rapidly, and the need for water in industry and agriculture is enormous. Climate change also adds to the problem: droughts restrict access to water even further, and flooding can pollute supplies of drinking water. Furthermore, these threats to our environment are probably only going to get worse. Already 1.2 billion people live in areas with limited access to water, and the UN predicts that, by 2025, this figure will rise to 1.8 billion, or two thirds of the world’s population.
But the problem isn’t only how much water we need, it’s also how we clean and store it. In the US, for example, water facilities are old and inefficient, and it’s hugely expensive to improve them. In China, the government knows it will need to spend $850 billion to improve its water infrastructure. Currently, India can only clean about 30 percent of its wastewater, meaning that people risk disease when they drink from polluted sources. Some countries filter sea water to make their drinking water. But this process is also very expensive, so it isn’t viable in many countries.
We can’t give up on this problem, however, because without water we can’t survive. Thankfully, there are already some excellent water purification products operating on a small scale, which are already helping people whose access to water is limited.
The “Slingshot” is a new water purifier, about the size of a small refrigerator, and is the creation of American inventor Dean Kamen. The purifier works by heating the water, which kills anything harmful. It can purify even the dirtiest water, requires minimal electricity, and can clean up to 1,000 liters a day. The “Slingshot” is already helping communities in several countries, including South Africa and Mexico. It will soon provide a cheap and safe supply of water in many other places where poverty prevents access to clean water.
Dean Kamen believes that every human should
have the right to clean water every day. Hopefully,
with more devices like the “Slingshot”, there will soon
be more water to go around.
Read the following sentences and, according to the text, decide if they are true ( T ) or false ( F ).

( ) Climate change doesn’t affect our supply of drinking water.
( ) India has 30 percent more drinking water than other countries.
( ) You use the “Slingshot” to keep your water cool.
( ) Dean Kamen thinks people should pay more money for clean water.

A alternativa correta é a letra E.
Vamos analisar cada uma das sentenças e entender o porquê da correta ser a opção E:
( ) Only a small amount of water on our planet is suitable for drinking.
Essa afirmação é verdadeira (True). O texto menciona que menos de um por cento da água do planeta pode ser facilmente usada como água potável.
( ) Climate change doesn’t affect our supply of drinking water.
Essa afirmação é falsa (False). O texto deixa claro que as mudanças climáticas impactam negativamente o fornecimento de água potável, mencionando que secas restringem ainda mais o acesso à água e inundações podem poluir os suprimentos de água potável.
( ) India has 30 percent more drinking water than other countries.
Essa afirmação é falsa (False). O texto menciona que a Índia pode limpar apenas cerca de 30 por cento de suas águas residuais, o que significa que as pessoas correm o risco de adoecer ao beberem de fontes poluídas. Não há indicação no texto de que a Índia tenha mais água potável do que outros países.
( ) You use the “Slingshot” to keep your water cool.
Essa afirmação é falsa (False). O texto explica que o "Slingshot" é um purificador de água que funciona aquecendo a água para matar qualquer coisa prejudicial, e não para resfriar a água.
( ) Dean Kamen thinks people should pay more money for clean water.
Essa afirmação é falsa (False). De acordo com o texto, Dean Kamen acredita que todos os seres humanos devem ter o direito a água limpa todos os dias, o que indica que ele defende o acesso à água limpa de forma acessível.
Por isso, a sequência correta, de acordo com o texto, é T • F • F • F • F, que corresponde à alternativa E.
