Why are humans interested in monitoring

It is especially important to monitor tides for people who rely on the sea for living - fishermen have to know the kinds of tides they are going to experience so as to decide whether to set off in search of fish or not. It is also quite important to monitor tides if there is some construction going on near the shore - for example, building bridges or docks, as when the tide comes, it may flood the whole thing. Scientists also study the tidal movements so as to better understand the circulation of the oceans. 
Hope this helps! :)

Unique question.well, using science, you cannot create or destroy even if you do eat yourself so you would not grow twice as big, nor would you disappear. you would stay the same but change states potentially, or at least change your appearance (obviously).hope this . keep up these unique questions.
