Florida’s Vanishing Springs
Deep beneath the ground we stand on, below the strip malls and the condos and the lush green of the golf courses, runs a river of water that makes life in Florida possible. The underground aquifer rushes through Swiss cheese caverns, its hidden flow bubbling up to the surface in Florida’s estimated 1,000 springs — the greatest concentration of springs on Earth.
A century ago Florida’s gin-clear springs drew presidents and millionaires and tourists galore who sought to cure their ailments by bathing in the healing cascades. Now the springs tell the story of a hidden sickness, one that lies deep within the earth. The video is contained in the following link:
The open sea covers about 70% of the earth to an average depth of about 2 miles. It is little wonder then, that some 312 species of birds in 17 families have adapted to this vast aquatic environment. These are the seabirds, that range in size from the large albatrosses with wingspans of up to 12 feet to the diminutive petrels that were named after the Apostle Peter by early seafarers because of their habit of dangling their feet in the water while hovering just above the sea surface, giving the appearance that they were walking on water.
Seabirds also include the Penguins, Fulmars, Prions (Whalebirds), Shearwaters, Boobies, Gannets, Puffins, Auks, Razorbills, Murres, Dovekies, Guillemots, Auklets, Murrelets, Gulls, terns, and some ducks and geese.
Because many species of seabirds spend most of their lives at sea far from the eyes of man, little is known about their habits, their movements, or their associations. Fortunately, increasing interest in these birds, and the publication of some excellent guides, has generated more interest in these birds and in their conservation needs.
Marine birds are present in a wider array of sea environments than are marine reptiles, because they are endothermic and extremely mobile. This allows them to maintain a more constant body heat no matter what the surrounding temperatures are.
