Social media is our new travel agent, and it's changing the places we go. In some cases, the places we go. In some cases, the newfound fame brought about by social media platforms has helped to boost local economies and bring tourists to places they might never have discovered otherwise. In other cases, it's creating problems for countries and cities that are simply not equipped to deal with the influx(涌入) of tourists. Check out two of the incredible locations around the world that have gone viral on social media.

    Iceland

    This northern island nation has seen a dramatic surge(激增) in visitors over the past few years. One reason for that is the so-called "Game of Thrones effect,". This, combined with the availability of cheap flights and some very effective marketing campaigns, has made Iceland a popular travel destination. The number of tourists almost doubled from 566,000 to over 1 million between 2011 and 2015, according to Iceland's tourism board.

    While this influx of visitors has brought a much-needed boost to the economy post-recession(经济衰退), it's also pushed up prices for residents and put pressure on the infrastructure. Locals complain of tourists destroying the fragile ecosystem and leaving a mess behind them as they trample over the formerly untouched natural sites.

    Cuba

    According to Cuba's ministry of tourism, four million visitors went to Cuba in 2016, an increase of 13 percent from the year before. The tourism boom has had some consequences for the country's residents, The New York Times reported in December 2016.

    The surge in visitors has led to a food shortage, and basic food items have become completely unaffordable for locals. Local hotels and restaurants are buying up supplies in bulk for guests, pushing up prices and leaving limited amounts for locals.

    The situation has been acknowledged by the Cuban government, who put caps on prices to make them more affordable for residents. This has only encouraged sellers to put products on the black market, according to The New York Times.

    Camping wild is a wonderful way to experience the natural world and, at its best, it makes little environmental influence. But with increasing numbers of people wanting to escape into the wilderness, it is becoming more and more important to camp unobtrusively (不引人注目地) and leave no mark.

    Wild camping is not permitted in many places, particularly in crowded low—land Britain. Wherever you are, find out about organizations responsible for managing wild spaces, and contact them to find out their policy on camping and shelter building. For example, it is fine to camp wild in remote parts of Scotland, but in England you must ask the landowner's permission, except in national parks.

    Camping is about having relaxation, sleeping outdoors, experiencing bad weather, and making do without modem conveniences. A busy, fully—equipped campsite (野营地) seems to go against this, so seek out smaller, more remote places with easy access to open spaces and perhaps beaches. Better still, find a campsite with no road access; walking in makes a real adventure.

    Finding the right spot to camp is the first step to guaranteeing a good night's sleep. Choose a campsite with privacy and minimum influence on others and the environment. Try to use an area where people have obviously camped before rather than creating a new spot. When camping in woodland, avoid standing dead trees, which may fall on a windy night. Avoid animal runs and caves, and possible homes of biting insects. Make sure you have most protection on the windward side. If you make a fire, do so downwind of your shelter. Always consider what influence you might have on the natural world. Avoid damaging plants. A good campsite is found, not made—changing it should be unnecessary.

    The computers changed our lives in the 1980s, the Internet changed our lives in the 1990s, and the robots will change our lives in the new century.

    Do you think there will be robots in people's homes? It's not a dream that every home will have a robot.

    Now, robots are not only able to help people do the housework, they can also help the doctors do the difficult operations, play chess with people, play the piano and so on.

    A new cooking robot is used in Beijing. It can cook all the dishes on the menu, you only need to wait two to four minutes. In the future, the robot will be a nurse, a security guard, or a partner in your life.

    Experts believe robots will be used everywhere from the industrial robots to service robots. In the future, robots will become part of the family, and provide close service for people. We all look forward to the new robot age.

    Lemurs are cute animals that live on the island of Madagascar, the fourth-largest island in the world. Lemurs have big eyes, long noses, and long tails(except for the Indri) and live high in the trees of Madagascan forests. Lemurs are quite intelligent. They are the cousins of monkeys and look quite similar. They also swing through the trees and live in family groups.

    There are different species of lemurs. Some lemurs (the Indri) sing like a whale, and some (the Sifaka) walk like a ballet dancer. Some lemurs are very small, like the Pygmy Mouse Lemur which weighs only 25-30 grams. Others, like the Indri, can weigh up to ten kilograms. Some lemurs are nocturnal, being awake at night and sleeping during the day, and some are not nocturnal but diurnal. Generally, the smaller lemurs are nocturnal, while the bigger ones are diurnal. All the species are unique to Madagascar.

    However, all of the lemurs are endangered species. Many species have already disappeared in the last few centuries. There are not many of lemurs left. People in Madagascar have been destroying the forests where lemurs live. Local people also hunt lemurs for food. Some of the local people see lemurs as bringers of bad luck, so they kill lemurs.

    At the moment, there are about 85 lemur species left. But many people fear that the number of species will fall quickly. Soon there may be no lemurs left if we do not make serious efforts to protect them.

    The United States Congress is responsible for making and approving federal laws—rules that everyone in the country must follow. But exactly how do those laws get made? The process is not easy, and it takes a long time.

    A law begins when someone puts forward an idea. The idea can come from anyone, but it has to get to a U. S. lawmaker who wants it to become legislation. In time, the idea is further developed into a written proposal, called a bill.

    Then, a member of Congress officially proposes the bill. After the bill is introduced, it is sent to a small group of lawmakers, called a "committee". Sometimes committee members seek more information about the proposal by holding hearings. Sometimes the committee changes the bill. Sometimes it decides not to take any action. In that case, we say lawmakers "table" the bill, or let it "die in committee".

    But now and then, the bill is offered to lawmakers not on the committee. Those lawmakers debate the bill further. They might change the bill again. Finally, the full House or Senate votes on the bill. If it does not earn the majority of votes, the bill does not advance.

    Finally, the agreed-upon bill is sent to the president. If the president signs it, the bill becomes a law. If the president does nothing and Congress is officially meeting, the bill becomes a law. But if the president does nothing and Congress is not in session, the bill does not pass. Or the president can officially reject the bill. If that happens, the bill is not stopped. Instead, it is returned to both the Senate and the House. If two-thirds of the senators and two-thirds of the House members approve the bill once again, even with the president objecting, they turn the bill into a law.

    You'll need to take a deep breath before hearing this news. An astonishing 93% of kids around the world live in environments with air pollution levels that are damaging their health, according to a new report by WHO.

    Air pollution is to blame for the deaths of 543, 000 kids under 5 in 2016, with more than one in four deaths of children under five years old being related to environmental issues. Exposure (暴露) to air pollution can damage the health of kids in a variety of ways, either causing or being associated with everything from low birth weight to childhood obesity and so on.

    "The large toll of disease and death revealed (揭示) by these new data should result in an urgent call to action for the global community especially for those in the health department WHO stated. "Strong action to reduce exposure to air pollution offers an opportunity to protect the health of children." The report stressed that health experts should communicate with families, communities and policy-makers about the serious risks of air pollution exposure. "Although more researches into how air pollution affects children's health will continue to be valuable, there is already evidence to justify strong, swift action to prevent the damage it clearly produces," WHO added.

    Disease caused by dirty air is more common in low-and-middle in some countries, especially those in Africa, South-East Asia, and Western Pacific regions. Poor countries in these areas have the highest levels of exposure to household air pollution due to the use of polluting fuels and technologies for basic needs like cooking, heating and lighting.

    Advised solutions include cleaner transport, cleaner cooking and heating fuels and technologies energy-efficient housing and urban planning, safer industrial technologies and better waste management.
