To me this proves we are all interconnected and the Pagans just maybe right

Now, knowing we are all interconnected and dependent upon each other.... from the smallest bacteria to the largest tree to man to the creatures 2 miles underwater...... shouldn't we all try to make sure we don't kill each other off.

Asteroid Impact Would Devastate Seafloor Life, Too

If an asteroid were to hit Earth and wipe out all life at the planet's surface, the creatures that live around deep sea hydrothermal vents would be safe from destruction, scientists have long thought. What goes on above the ocean's waves should be of little concern to creatures living 2 miles below.

But apparently it is, new research finds.

During a global catastrophe, the shrimp and mussels that thrive around these vents may be just as doomed as the rest of us.

Creatures such as bacteria, shrimp and snails have flourished around hydrothermal vents, despite the fact that no sunlight reaches to the depths of the ocean floor. Instead, colonies get nutrition from the minerals dissolved in the superheated water that spews out from the vents.

Through a process called chemosynthesis, microbes convert the heat and minerals produced by the vents into energy. They then provide food to more complex forms of life, such as mollusks, crustaceans and worms.

Scientists had thought that because the food source of the creatures living around the vents was independent from the world above that an event such as a giant asteroid collision, which can kick up a cloud of debris that blocks the sun for months or years, wouldn't affect the vent ecosystems.

But new research done by Jon Copley of the University of Southampton indicates that the offspring of some of these creatures grow up away from the life-sustaining vents and depend for food on whatever material sinks down from the sunlit surface waters.

In fact, the vent inhabitants time the birth of their offspring with the seasons—even though they cannot see the sun. They time the release of their young to the spring bloom of the microscopic plant life that grows on the ocean's surface—stuff that sinks after it dies.

"I used to think these deep-sea communities would be safe from whatever havoc happens up here," Copley said. "But finding seasonality down there shows that life beneath the waves is far more connected than we realized."

Copley, who presented his research at the British Association for the Advancement of Science's Festival of Science, warns that because of this newly discovered susceptibility, deep sea vent communities could be impacted as climate change alters life in surface waters, though researchers have not found any evidence of climate change impacts in the deep ocean yet.
The other thing of note..... if these creatures 2 miles underwater know seasons...... then perhaps the Pagan's are right... Earth mother truly is.
