'Water's Pulse' is a cautionary lesson on the influence the human pollution is having on underwater species.

This episode discusses the environmental impact carbon dioxide is having on the dwindling atmosphere that encapsulates Earth, and how the changing temperatures impact glaciers, water temperatures and the climate of several ecosystems across the globe.

'The Big Blue# provides a general overview of oceanic life, which includes the migratory patterns of whales and turtles and creatures from the deep.

This episode moves one step closer to land, presenting viewers with a glimpse of the ecosystem in various smaller bodies of water.

We're provided with an analysis of the symbiotic link between algae and coral: the complex formation of coral reefs help nurture, protect and shelter the various creatures that hide in the crevices of the beautiful reefs.
