Glow of lights reflected

The region underneath these clouds is called Westland because it's situated in the West of Holland ~ up till half a century ago it had its nickname of Glass-City, because here the glass warehouses stand where veggies and fruits are planted and since there's lots of competition in the fruit market, flowers are grown here too, since some decades.
And all those plants need warmth and  light to grow fast; the glow of light we see reflected in the clouds... A kind of sky pollution we think it is.
