Unsere Erde wird nicht zufällig «Blauer Planet» genannt. Zwei Drittel der Erde sind mit Wasser bedeckt. Neben dem Einfluss auf Wetter – und Klimaphänomene bietet das Wasser aber auch Lebensraum für unzählige Formen von Lebewesen. Selbst der ferne Mond nimmt Einfluss auf die riesigen Weltmeere.
It's ironic that we call our planet 'Earth', when two thirds of its surface are covered by water! The oceans, with their fluctuating water temperatures and global currents, also act as a driving force for local weather phenomena and global climate change. In addition, they provide an immense habitat for a countless variety of species. Some of the most important are microscopically small plants and bacteria. Under the right environmental conditions, they can be seen from space in one of nature's most mysterious spectacles, the algal bloom, a sudden mass reproduction of phytoplankton that changes the color of vast bodies of water into a creeping, luminescent, blue-green expanse. A wonderful vision, but as is so often the case in nature – what is good for some is deadly to others.
La vita del nostro pianeta è legata agli elementi. Meraviglie geologiche, clima spettacolare, misteri dei regni vegetale e animale, tutti indissolubilmente legati e plasmati da Aria, Terra e Acqua.
