The cruise（邮轮） tourism is the fastest growing industry in the travel industry. With rapid growth in the number of passengers, the number of cruise ships at sea, and the increased variety of destinations, the fast growth in the industry follows with increasing influences on the environment.
Like many travel industries, the negative influences on the environment seem to outweigh the positive ones. Even though the cruise industry is relatively small compared to the airline industry, cruise ships and their passengers generate more waste and pollutant emissions（排放物） while travelling and docked in port. According to the United States Environmental Protection Agency, a one-week voyage generates more than 50 tons of garbage, and during that same week 3.78 million litres of waste water is produced. That is water which is harmful to the ocean life and cannot be poured back into the ocean without being treated. These numbers are multiplied by more than 200 cruise ships sailing the world 365 days a year.
Due to pollution, coral reefs（珊瑚礁） are taking a significant damage. There are 109 countries with coral reefs. In 90 of them, reefs are being damaged by cruise ships. It is said 70% of cruise destinations are in the spots with the existence of a wide variety of sea plants and animal species.
However, it is not the amount of pollution generated by cruise ships that is most concerned, but rather, the way cruise ships deal with their waste. The way cruise ships get rid of waste is highly unregulated. Waste can be poured a few short miles off shore, which is later brought back to shore due to ocean currents. In most cases, there was no monitoring or administration from local authorities if cruise ships violated the pollution standards. The cruise industry continues to promote itself as environmentally friendly; the truth is, there are many examples of cruise ships breaking the law.
Processing waste on board is not impossible for cruise industries. Since the increased harmful effects on the environment have come to light, some cruise industries have done their part and as

technology increases, their ability to become more eco-friendly has become the most important.
Holland American Line has invested $1.5 million into a program called Seawater Scrubber Pilot. This program looks for opportunities to reduce engine emission on its ships. The Sea Water Scrubber system uses the natural chemistry of seawater to remove all harmful materials in the seawater before it is poured overboard. Even though it is only a small step, it makes a big difference.
The environmental impact of the cruise industry on the destination has negative effects. However, with effort made, there is still hope that these effects can be limited, or as we wish, reduced.
47. What adds to cruise ships’ pollution? A. Lack of proper regulations. C. Service system on cruise ships.
B. Growing size of cruise ships. D. Useless water-treating program.
48. Why did the author mention Holland American Line? A. To stress environmental protection matters. B. To evaluate the effects of natural chemistry. C. To introduce the Sea Water Scrubber system. D. To prove some anti-pollution measure works. 49. What is the passage mainly about? A. Influences of cruise tourism. C. Consequence of ocean pollution. 50. How is the passage developed? A. By analyzing cause and effect. B. By discussing problems and solutions. C. By comparing benefits and disadvantages. D. By presenting similarities and differences.
B. Problems in tourist industry. D. Administration of cruise emissions.

Earth is experiencing its sixth mass extinction: somewhere between 30 and 159 species （物种） disappear every day, and more than 300 types of animals have died out since 1500. This is not good for the future of life on our planet, but what if we could make some of the extinct species come back to life? Thanks to ongoing advances in DNA recovery and cloning technology, de-extinction may soon be realized, and we may see Tasmanian Tigers, or Dodo Birds back into existence in the near future.
Some scientists are confident and optimistic about de-extinction. They think that the best reasons for de-extinction have more to do with ecology than tourism. “If this is always going to be a zoo animal, then stop,” says Ben Novak, the lead researcher at Revive & Restore-a foundation devoted to rescuing endangered and extinct species in San Francisco, California. “The goals have to be about ecological restoration and function.”
Take passenger pigeons for example. Their numbers reached nearly 5 billion at the start of the 19th century, and they played an important role in shaping the forests they inhabited(居住). After their extinction, the forests have never been the same. “The passenger pigeon is a very important ecological species if we want their original habitat back,” Novak says.
However, we need to think twice about Novak's idea. Any new scientific initiative is bound to have risks, so is de-extinction. Although some assume that de-extinction may help the environment, we can’t be so sure. The de-extinct animals would now be strangers to their habitats. As the habitat is no longer what it was, the species role within the ecosystem may have also changed. This could be actually a threat to the other species within the environment as the de-extinct animals enter the area and compete for food sources. Once again we’re trying to force nature to act in a certain way, rather than letting it remain natural.
Many scientists also believe that priorities (优先权) would change within the conservation of currently endangered species. Would we still put in the effort to preserve living animals if we knew we could just magically bring them back from-the dead? Douglas McCauley, an ecologist at University of California, Santa Barbara, stresses this worry. “Honestly, the thing that scares me most is that the public absorbs the misimpression that extinction is no longer scary. The general attitude becomes: Deforest, no worry, we can reforest. If we drive something extinct, no worry, we can de-extinct it.”said McCauley.
