what is the meaning of locomotion

Efforts are created to protect once abundant asiatic elephants.Elephants are threatened by poaching for tusks,from the decrease of habitat due to human pressure on forested areas and due to human conflict.The isolated populations of wild elephants in individual wildlife sanctuaries can also be threatened by decrease of genetic diversity.Recently several corridors connecting wildlife sanctuaries have been in existence to encourage the migration of wild elephants. The woodwind section will glare in the drummers. The brass section sticks their noses up at them. And then they emerge about the field one day minus the drum line and you know what? No one can march for the life of them. No one can keep their steps. Lines are squiggling forward and backward. Formations which are once crisp and defined have become sluggish and bloated looking. That perfectly formed capital 'O' this rock band worked so difficult on a week ago now resembles a half-hearted 'U'. What is wrong with everybody?
