you provide unique information. PLEASE ALSO directly mail me a copy of

1. Given a large ark containing 2 individuals of every animal species
in the world, what would be the approximate total weight of all the
organisms? How would your answer differ if you included every plant,
bacterial, and fungal organism?
2. Assume that all other organisms on earth were dead except for those
on the ark in question 1, and that the animals were released 1000 years
ago. What would you expect to be surviving today? (Assume that, where
applicable, a male and female were used for each species.)
3. Assume that the year is 1992 and that it rained for 40 days, and the
rain covered all the land on the earth. Further assume that the flood
waters receded to pre-flood days within several months.
What would be the geopolitical changes as a result of the
temporary flood?
What would be the ecological changes as a result of the
temporary flood?

Were you thinking of parthenogenesis or something ???

Dunno about this but it's a safe bet that the Netherlands _wouldn't_ get flooded
We've been blocking the sea out for hundreds of years, so we've more experience
at it than anyone else.

Just my opinions, nobody else's, especially not Oracle's

1000 tons (guessed 10 million species with an average weight of 100 grams,
insects push this number down with their huge number of species).
No increase through bacteriae or fungi, but maybe with plants.
(You were unspecific: All living species?)

None. I think it's common knowledge with biologists that you need at least
~50 individuals of a species to keep genetic health --- aside from the
problem of both a male and female baby surviving.

"Covers the land." How deep? To cover *all* land (Himalaya) evenly, you
need a depth of 9000 m in most regions, so the question is, how fast will
it rise? Do we just have time to put some tins in the boat? Most people
don't have one. Most airplanes cannot land but maybe some of them swim.
One has to calculate the distribution of swimming things in usual locations.
For if people have to swim 500-1000 m in cold water to a beam, most will
drown.

With the survival of at most 1 percent of the population there will be a
completely new beginning. Don't know if they would make the same mistakes,
though. Technology will be thrown back, and science more than that.
Niven/Pournelle's "Lucifer's Hammer" is an accurate description.

Lack of most animals, especially those dependent of plants (many of them
can't live without a day of food). Most plants will grow again after some
time.
