A living thing needs at least one cell, it needs to reproduce and take in energy, and it needs to grow and develop according to genetic instruction. Living things need to have all these characteristic and more. But to me, LIFE, is more. Life is activity, motion, and excitement. Life is reliance on certain balances, and striving to achieve them.
Life is interaction with surrounding elements, responding to environmental changes.
Life is all living things intertwined in one huge planetary equilibrium. Life is a state of being, always changing and adapting. Life is struggling to maintain certain necessities, while enjoying and reacting to adjoining life. Life is an exertion, at times to achieve one major goal, at others to survive. Life is an on going process, each day extending, which is affected by every motion, decision, and thought.
