Captain Nemo's dream
There are a lot of forms of living, but one year ago someone said me that some Japanese engineers wanted to do houses underwater because, they wouldn't have enough space to build houses. I couldn't believe it, but it was true. I saw it in the news, in spite of this I haven't seen anyone living underwater, except Jacques Cousteau.
On the one hand, I think that living uderwater could be really difficult, because your house can be broken and you could drown. Another important fact is that it would cost a lot of money and not all people could live there. Moreover, you won't breathe fresh air in these types of houses.
On the other hand, it could be an important fact to think about because our planet could be polluted and we must have a place to escape. It could also be really amazing to live underwater for more than a week.
All in all, it's only an experiment, so we can learn how it works and how it will finish, it can finish bad. However, I think that they are lucky to do this experiment, but they have to pay attention to sharks.
