A valley can be described as a hole in the earth's surface with two larger pieces of land on both side. In Malta, the valley system is one of the most important habitats. Sadly, the wonderful habitat is not appreciated and some valleys have become nasty dumps. While more and more valleys get dirtied up people should try to help the valleys stay clean.
Heavy machinery can be very destructive to the valleys.
People need to begin to appreciate the valleys and to keep them clean.
