Default National Geographic and water hyacinth

Reminds me of St Johns US Virgin Islands.

The ships brought in rats by accident, then the plantation owners brought in
snake to kill rats, snake is out of control.

Then comes mongoose to eat snake, now mongoose is totally out of control.
Being that it is an island, and no mongoose predator, mongoose remains out
of control, eating domestic livestock, etc. decades later still no solution
to mongoose problem.

Moral of the story: Left alone nature will not screw up!

Hi all. I just watched a special program on National Geographic channel
about how water hyacinth is taking over Lake Victoria in Africa. They

said
it doubles in area every 14 days! Apparently there is so much of it
fishermen get stranded in it for days and must be rescued. It's messing

up
the ecosystem there as well as keeping people from making their only

means
of income. And to think I wanted to put some in my pond this spring...

and now for the rest of the story


1st, Lake Victoria is about the size of NY state!


a resort hotel brought the WH in to clean the water
so people could swim in clear water BUT! then the WH
started taking over.


the resort hotel now brings in a fish to eat the WH,
the Nile perch (3'+ adult) and only worries about
being eaten by Nile Crocodiles.


the Nile perch now decides that the WH isnt as good to
eat as the local cichlids, haps. etc. and decimated
the indigenous fish population to near extinction
the only survivors were the smaller types that could
hide in the rocky areas.


a captive breeding program was started in the early 70's
to replace the near extinct fish but wasnt nearly enough
to restock the ind. species
