Without friction. everything would slide about, similar to what happens when you walk on ice. Friction enables objects to remain in position, keeps cars from skidding etc.

1) In machines the mechanical parts which rub with each other wear out. 2) Due to friction between the sole of the shoe and the floor the sole wears out. 3) Tyres of vehicles wear out because of friction. 4) Energy is wasted in overcoming the force of friction.
1) Prevent things from moving past each other (while touching) 2) create heat
when you walk; wheels roll to move cars; you grasp something in your hand; cars brake; these are all because of friction. Really there are advantages of friction.
Rolling friction is less than sliding friction so it is easier to move heavier objects using wheels.
it is because of friction that we are able to stand and sit anywhere.
