Today, some people choose to visit some places such as the Sahara desert or the Antarctic, this is because they believe these kinds of activities are very thrilling and exciting. I believe that these activities could be very memorable experiences. However, they could also bring lots of problems. Indeed, most people love new things which can help them a lot. For example, travelling to a new place with harsh conditions can make people feel stronger and more confident. Also, they can learn a lot of new things which are beneficial to their self-improvement. Furthermore, they can enjoy being in a new, exciting environment that they have never experienced before, that would be a very plesant journey, wouldn't it? Nevertheless, there are still some disadvantages when people go to some dangerous places. The biggest one is that this kind of behaviour is very risky since these places are always in awful conditions. Take the Sahara desert for example, the first danger for visitors is the lack of fresh water. People can't live for more than three days without drinking anything. Also, people can easily get lost in the desert since there are sand dunes everywhere, it's hard to find a reference to know your direction. Besides, visiting these dangerous places would cost you a lot of money, and it's also bad for the enviroment since nobody does the cleaning work. In conclusion, in spite of the benefits to visit some places with bad conditions, people should pay more attention to the disadvantages. If they decide to go there, they would have to prepare for it. For example, making a plan with careful consideration, thinking about the difficulties and risks, keeping in touch with family members. Being prepared would be very helpful.
