The Pros and Cons of Nuclear Power
Since the disaster at the Fukushima nuclear power plant in Japan in 2011, a debate has been raging (1) the future of atomic energy. Consequently, the safety risks have been well publicized in the global media. But do the risks outweigh the damage that could be done to the planet because of our ongoing addiction to fossil fuels?
Even environmentalists don’t have the answer. They are split over nuclear (2) , and its pros and cons. Some say it is neither safe nor economical because it produces potentially (3) radioactive waste, and reactors are so costly to build. However, others believe nuclear energy is a necessary evil. They say we should continue using it until (4) energy sources, like wind turbines and solar panels, can meet global demand. Supporters also argue that nuclear energy helps cut down on carbon emissions from fossil fuels such as coal and natural gas, which are linked to global warming and pollute the environment. They say this is because nuclear reactors produce a tiny fraction of the carbon dioxide generated by burning coal.
But perhaps the biggest hurdle for atomic energy to overcome is its image problem. Despite industry claims of a strong safety record, critics remain unconvinced because each reactor annually produces up to 30 tons of nuclear waste, which can continue to be radioactive and hazardous for thousands of years. Furthermore, the Chernobyl disaster in 1986 left the public with vivid images of the impact of a nuclear meltdown, including deformed babies, mutated vegetables, and abandoned towns.
While nuclear reactors may continue to be installed in some countries for decades to come, after Fukushima others have decided to rethink their energy policies. For example, the German government has revealed plans for a “green” renewable energy plan, even though it has relied on nuclear power for up to 23 percent of its consumption in the past. It has been announced that all seventeen nuclear power plants would be phased out by 2022. The policy will also promote energy-saving measures encouraging people to insulate their homes, recycle, and reduce waste. Experts argue it could be a risky strategy because Germany doesn’t have natural gas or oil supplies, and coal supplies have been depleted.
Meanwhile, in Brazil, there is just one nuclear plant at Angra dos Reis. Nuclear power represents only three per cent of Brazil’s energy production. After sharp oil price rises in the 1970s, the country’s leaders anticipated future energy supply problems. So they concentrated on developing alternative energy sources including biofuel, hydroelectric schemes, and wind power.
This approach seems to be working because by May
2012 plans to build more nuclear reactors were shelved by Brazilian officials. The move was welcomed
by environmental lobby groups, which had feared a
potential ecological catastrophe in case of an accident. If a big country like Brazil, which is the tenth
largest energy consumer in the world, can survive and
improve its economy without much nuclear power,
maybe others can do so, too.

Fake news: improved critical literacy skills are key to telling fact from fiction

Quais das palavras abaixo têm o mesmo significado que vast, verify, rational e passive?
Counting carnivores is a tricky business. Individual identification is a tremendous challenge and requires highresolution cameras or good, unobstructed views in person. They are often shy and cover large distances. Lions are difficult to count even though they are social and sleep most of the day. Only a very few lion populations are known at the individual level, such as Liuwa Plains National Park, Zambia. Individual recognition of every lion in an area requires intense study, significant resources, and low numbers of individuals. Therefore, researchers use a variety of other imperfect techniques to estimate lion population size in all other lion areas. Some more common estimation techniques include spoor tracking or call-up surveys.
The drastic reduction in lion numbers and habitat highlighted by our research is certainly alarming from a conservation standpoint. Yet, African lions are not in immediate danger of extinction. Substantial lion populations exist in large, well-protected areas such as the Serengeti or Kruger ecosystem. Many of the remaining lion populations in East or Southern Africa are in well-protected areas such as national parks and game reserves (although some of these allow hunting). Nevertheless, this should not be used as a blanket statement; there are populations and even countries in these regions that have few or no lions remaining. Overall, lions in West and Central Africa are in the gravest danger of extinction. More than half of the populations vital to lion conservation in these regions (as noted by the IUCN) have been extirpated in the past five years, with several countries losing their lions entirely. According to our research, fewer than 500 lions remain in West Africa, scattered across eight isolated sites. This is of serious concern as these populations contain the most genetically unique lions in all of Africa and are most closely related to the Asiatic lion.
You cannot protect what you do not know you have. This is a simple but true adage. Our compilation needed to occur in order to prioritize areas for conservation action. With a good map, numbers, and some understanding of connectivity between the lion areas, we now know which populations are threatened with extinction or conversely, which are well connected and well protected.

When is it time to stop studying?
It's 10 p.m. and six government employees are out checking the streets of Seoul, South Korea. But these are not police officers searching for teenagers who are behaving badly. Their mission is to find children who are still studying. And stop them. Education in South Korea is very competitive. The aim of almost every schoolchild is to get into one of the country’s top universities. Only the students with the best grades get a place. The school day starts at 8 a.m. and the students finish studying somewhere between 10 p.m. and 1 a.m. at night. This is because many go to private academies called hagwon after school. Around 74 percent of all students attend a hagwon after their regular classes finish. A year’s course costs, on average, $2,600 per student. In Seoul, there are more private tutors than schoolteachers, and the most popular ones make millions of dollars a year from online and in-person classes. Most parents rely on private tutoring to get their children into a university. With so much time spent in the classroom, all that students in South Korean high schools do is study and sleep. Some of them are so exhausted that they cannot stay awake the next day at school. It is a common sight to see a teacher explaining the lesson while a third of the students are asleep on their desks. The teachers don’t seem to mind. There are even special pillows for sale that fit over the arms of the chairs to make sleeping in class more comfortable. Ironically, the students spend class time sleeping so that they can stay up late studying that night. The South Korean government has been aware of the faults in the system for some time, but now they have passed some reforms. Today, schoolteachers have to meet certain standards or take additional training courses. However, the biggest challenge for the government is the hagwons. Hagwons have been banned from having classes after 10 p.m., which is why there are street patrols searching for children who are studying after that time. If they find any in class, the owner of the hagwon is punished and the students are sent home. It's a strange world, where some children have to be told to stop studying while others are reluctant to start. Adapted from: LATHAM-KOENIG, Christina & OXENDEN, Clive. American English File 3 - Workbook. 2"“ edition. Oxford: OUP, 2014.
In the sentence “However, the biggest challenge for the government is the hagwons.” (last paragraph), the word HOWEVER could be correctly replaced in this context, without change of meaning, by:
