Hurricane Lament
Are animals deep in the sea also suffering while Hurricane Harvey
rages above the surface?
Surely sea creatures are better adapted than is downtown Houston
to crashing wind and wave, endless rain.
But is it really better down where it's wetter?
I perused some reliable marine science sources:
-Some marine animals, like sharks and dolphins, can sense the coming
change in barometric pressure, and have been observed escaping danger by swimming
deeper.
-Many fish and invertebrates are tossed like so much flotsam and
jetsam on shore to die.
-All that extra fresh rainwater, lighter than salt water, sits on
the surface and prevents oxygen from getting down to deep sea critters -
anaerobic suffocating to death.
-But the worst hurricane effect, if seems, is to coral and other
filter feeders. (Yes, coral is an
animal.) In one study coral cover
was reduced by about 17% in the year following a hurricane. “Wave action increases turbidity and
sedimentation, which lowers light penetration to the photosynthetic algae in
the coral's tissues, and also directly kills the coral through smothering, as
the substrate particles clog cilia on their tentacles. The heavy rainfall
associated with hurricanes alters the salinity of the water, which is an
additional stress for the fragile marine life.”
Watching the awful
images of Harvey’s devastation and death to land animals, including humans, and
that vicious storm swirling above not just land but Gulf water, I began with a
question, and did some research.
But I end with a
lament, in the style of the Psalmist, “How long, O Lord?”
How long will we
inflict pain and suffering on the water and creatures in the Gulf of
Mexico?
For years we have
sent agricultural fertilizer down the Mississippi and created a dead zone in
the Gulf the size of Massachusetts. And
now this?
We have built oil
towers throughout the Gulf, like the Deepwater Horizon and so many others, that
have become towering infernos of toxicity and death. And now this?
We have driven and
flown and put so much CO2 in the Gulf that its temperatures have risen 4
degrees in just a few years, so that hurricanes hit the shore at greater and
greater speed and their clouds are more and more saturated. And now this?
All that carbon is
making the Gulf much more acidic and the coral is weakened and starved and
bleached in these repeated “mortality events from multiple stressors.” And now this?
Now this
happens? The turbulence and sediment
from these hurricanes made worse by our actions are also suffocating and
starving the coral?
As on land, some
undersea regions are miraculously spared hurricane damage and others even more
miraculously resurrect in new seasons.
But coral grows very slowly. The
Gulf is getting only warmer, more acidic and deader. Storms are coming faster and more often.
How long?
On our Blue Theology service trips and pilgrimage retreats we see beauty, and we pray “Thank You God” and “Wow!” And even in Monterey Bay we see the effects of climate change, and we pray “We are Sorry” “Help” “How Long?” Come pray and learn and serve with us, bluetheology.com. I post these “Tide-ings” every Wednesday.
