    As relevant today as it was in 1985 and even more urgent!! from plastics to oil spills and now climate change.... Too bad our prime minister didn't watch this film when he was young.

  • I didn't know that food chains could be found underwater ! A typical rocky shore can be divided into a spray zone or splash zone (also known as the supratidal zone), which is above the spring high-tide line and is covered by water only during storms, and an intertidal zone, which lies between the high and low tidal extremes. Along most shores, the intertidal zone can be clearly separated into the following subzones: high tide zone, middle tide zone, and low tide zone.
