Sign of human stupidity

I just don't understand why some people are so lazy or thoughtless, that they leave their waste in nature. For example this fridge has been abandoned in the middle of the forest!!! It seems to be laying there many years already, so there might have been kind of road long time back, but now nature has been taken it over totally. Now there isn't any possibility to go there by car as the nearest road is about 300 meter away. This kind of stupid behavior makes me mad and sad at the same time:(
