Coasts
Shapes and Formation
The border area of the ecosystems of land and sea, which influence each other, is referred to as coast. Depending on their shapes, the coasts can be few to several kilometres wide and are constantly changed by surf, tides, sea level fluctuations and coastal currents in the zone of influence. These processes have both destructive and constructive effects and result in different types of coasts.

Air Traffic
Being able to fly has been a dream of humanity from time immemorial. But it does not even date back a century that people actually started being able to travel through the air. Since the 1960s, the number of flight passengers has been constantly increasing. Thus, the airspace is no longer dominated by birds but by man-made flying objects.
