Since 1992, June 8th has been World Ocean Day. It is a well known fact that the worlds oceans cover more then 70% of our planet and June 8th is the day to appreciate our vast and amazing oceans. www.gdrc.org brings us more on World Ocean Day.
The world’s oceans cover more than 70% of our planet’s surface and the rich web of life they support is the result of hundreds of millions of years of evolution. Nomadic peoples were collecting shellfish and harvesting fish long before the dawn of settled agriculture. Great human civilizations, from the Egyptians to the Polynesians relied on the sea for commerce and transport, and now, at the end of the Twentieth Century, our fate is as tied to the oceans as ever. We still rely on fish for a significant portion of our daily protein needs, and more than $500 billion of the world’s economy is tied to ocean-based industries such as coastal tourism and shipping. Perhaps most important, this vast mass of water acts to help regulate the global climate and to ensure that a constant flow of vital nutrients is cycled throughout the biosphere.
But all is not well in the sea. Increased pressures from overfishing, habitat destruction, pollution and the introduction of invasive alien species have combined in recent decades to threaten the diversity of life in estuaries, coastal waters and oceans. Now a new threat, global warming, is making itself felt, and its impacts could be devastating for life in the sea.
