There are no reasonable scientific explanations for rivers, waterfalls and rain
(India) turning blood red over the past 2 years (starting in March 2010).
Some have said it must be an algae bloom, but others say no algae bloom could
explain these things. The first one that comes to mind is the waterfall in Antarctica:
it's too cold there for algae.
One curious opinion from "experts" in India said that it is due to a microbe that
has no DNA, and it could be extraterrestrial. But no one has any isolated samples
of such microbes.
The common theme seems to be that there are different reasons given for each
occurrence, like when birds were dropping from the skies or fish kills washing up
on the shores of oceans: no one, single cause was announced, always a different
reason, or several reasons offered for any particular instance. "Changes in
magnetic field could be responsible for massive bird and fish die-offs" (BBC).
Dead seals in Labrador, and then crickets in North America.
This summer, there has been a curious absence of flying insects in Los Angeles,
CA. Last summer there were lots of flies, mosquitos and moths, but not this
summer. I know someone who spent the summer in Minnesota. Another friend
said that he's from there, and the "state bird is the mosquito." But this other
person, coming back from MN, said there were very few mosquitos.
So far, it seems the only credible explanation is Apocalypse xvi. 4.
