One note on "conserving nature". With pictures.
This
(plus another link)is Crown of Thorns, a beautiful deadly species,
which — having been relieved of its regular
natural predators control — are eating up *all*
of our ocean as we speak,
and — being (uh) thorny and venomous —
they usually fail to make a terribly good
company while you relax bathing in the sea
with kids, but are surely a great sight while
diving — if you don't get bored to see it over
and over and over and over again.
Now this
(plus another link)is Napoleonfish, which is a kind of fish which can make
all your open water diving training — starting with your birth —
suddenly worthwhile. It is the size of a human and
sometimes much bigger and it *may* want to come
close.
And it can eat Crown of Thorns.
There are efforts of controlling population of both species
by humans, the second is threatened, the first is a threat
as a result of that.
So, you see, there is nothing good for nature or bad for
nature, it's just what you feel, the way you are bound.
