Although there are already robots which can do this job, rats are better. Christian Linster at Cornell University，New York，says，“Robots’ noses don’t work well when there are other smells around. Rats are good at that.” Rats can also see in the dark.They are cheaper and quicker to train than dogs, and unlike robots, they don’t need electricity!

The “rat project” is not finished，but Julie Ryan of International Rescue Corps in Scotland says, “It would be fantastic. A rat could get into spaces we couldn’t get to，and a rat would get out if it wasn’t safe.” Perhaps for the first time in history, people will be happy to see a rat in a building (but only after an earthquake, of course).

Tourism can be both good and bad.  16   but it may also bring some problems.

One growing problem is tourists who want to prove that they have visited a destination. Tourists have used paint, rocks, or even keys to write on the Luxor Temple in Egypt, the Colosseum in Rome, Stonehenge in the UK, memorial stones at the bottom of Qomolangma, and many, many other places. Thousands of tourists sites are being destroyed by tourists who“love them to death”.  If you want to leave a mark on the world, do it by changing someone’s life with kindness and love. Pass kindness along to future generations, not destruction.
