History of Man and the Oceans

To Save a Blue World, we must look at history.  Seleucus of Selucia correctly found that the moon causes tides in the ocean.  Man has loved the seas since that time.  For instance,  Pliny the Elder had many tidal observations.   Furthermore, the first Tide Table in China was written in 1016 AD https://en.wikipedia.org/wiki/Tide Source: Wikipedia

Modern film also shows a watery world.  Recall the 1995 Sci Fi “Water World”.  Do you recall the epic movie “Atlantis” which had a lost continent?  It existed somewhere near the present Caribbean sea.  Concern for ecology lead to songwriting.  Thus,  “Fish full of mercury” was a phrase in a pop song of the 1970’s by artist Marvin Gaye titled “Mercy, Mercy, Me (The Ecology)”.  See https://en.wikipedia.org/wiki/Marvin_Gaye

The Role of Debris and Garbage

There was a swirling build up of  plastics and ground up plastic in two oceans sometime before 1988.  These are the Indian Ocean and the Great Pacific garbage patches.  Much of this garbage still exists today. Source: Wikipedia  Therefore, ocean cleanup efforts are currently being tried for the first time.    Dredging, filtering, or encapsulating are ways of plastic removal.  Ocean plastic can be recycled or reused in some cases.  You will note that recent dredging efforts have failed as the dredging boom used to scoop up the plastic lets the particle through and is not working.  Currently engineers are trying to solve this problem.   Source: http://www.forbes.com


The pollution of the Oceans is perhaps this generations’ greatest challenge.  Also the shorelines.  You can find pictures online of whole lengths of shoreline and intertidal zone packed with plastic bottles and litter, particularly in areas such as India and Bangladesh.  The problem seems terrific at first glance, yet efforts are underway to remove this litter.  The oceans are said to have become “tarnished” which is a gloss word for “spoiled”.  The oceans are a great resource and every effort should be made to protect and respect them.

Plastics in oceans are an issue among biologists.  Plastic straws are of particular concern. Damage to the coral reefs is another.  See http://www.lteconomy.it/blog/2018/09/25/ocean-acidification-and-coral-bleaching/.     A useful article on plastic pollution is  http://www.lteconomy.it/blog/2018/09/25/what-are-the-major-impacts-of-plastic-pollution-in-ocean/

Treasures of the Sea

Only in the ocean could you find deep water lantern fish.  Also, there is  the octopus and it’s cousin the squid.  There is also a whole variety of  plant life.   These species are all subject to destruction by the actions of man.  To put a time frame on this picture, the time is now.   There is nothing like the present moment.   In conclusion: the scene is partly in your hands:  What will you do?
