If the World is meant to be realistic, where do hopes and dreams come from? They wouldn't exist in the first place.
Like all organisms on Earth, reproduction for survival is our prime aim on this World. To sustain our species. If so, why are we fighting against each other? Shouldn't we love and care for one another for we are who we are? We belong as one. Shouldn't we stand as one? Why the riots/killings/protests/schemings.. blah blah blah.
Aren't you tired of all the fightings and quarrellings? No? But I feel tired for you.
Seriously, what has the World become? This is no healthy competition!
Human lets just learn to be more appreciative and add 'satisfaction' to your dictionary.
EVERYONE OUGHT TO LEARN ECOLOGY!
