So what, now our light is polluted as well?

Not at all... light pollution is the call-name for pollution and hindrance caused by irresponsible, ineffective and dangerous (mostly outdoor) lighting. More and more, negative effects of too much light at night on health, economy, safety and the environment are understood.

By just being a little bit more conscient about the effects of outdoor lighting, a lot of risks and problems can be avoided.

I myself am a very active member of the Workgroup Light Pollution of the Belgian Astronomy Association, and am also a member of the organisation "Prevention Light Pollution".
