Tree

Tree has played a vital part in the human inhaling system. One might not know this, but tree is the most valuable companion, which has kept the human race alive for centuries. Tree releases oxygen, which human take in and exchange carbon dioxide for tree to nourish and regulate its system as well. This means that they both cannot be alienated from each other. What else, on the planet, may fall apart if having been separated from each other? Conversely, what else, if sticking together or having the same kind, will not make a move, progress, or grow? When it does sit still, it can be leveling as staying in the comfortable zone or lack of creativity. Yet, at the same time, it might be safe to do so for the sake of security. Whether one may choose to remain in -  It is a choice of an individual.
