Because you have too comform life here... treasure and
appreciate what you have now, and compare with other country, we
are too good life here.... 
Last time i dun even notice those flower and plant around us, after
one of my friend always ask me look at those beautiful flower and
plants, i will feel happy and fresh mood, thanks for i still have a
healthy body and an eye and see so many beautiful things....
