Water Property

If it "contracts at freezing" - it ain't water.

Frozen water doesn't support life, but it doesn't necessarily destroy it either.

Fresh water has a maximum density at about 4.2degC. That's why ice forms on the top and fish swim underneath the ice.

If we are theorizing on the effects this change in the property of water will have on life don't. Because you can't change this property of water. There is no way to test any part of your theory.

You really need more understanding of basic science before asking such an uninformed question.

I suggest you start with:

Or were you just wanting an answer without having to do any work on your own?

Well, it won't support polar bears....

probably the polar regions will be full of ice by now. If that's the case, as water became ice it sunks on the bottom of the ocean and so there will be a perpetual ice making. Ice is more to a heat insulator compared to water.

As to the effect of liquor drinking, its really nice, you can zip the beer without trouble of touching your mouth on ice cubes. Which I think is cool..lol

Ice in beer? Perish the thought!

It do not supports. You might have heard so many climbers, once fallen, get burried in the ice and never comes back. Future trevelers may find their body intact but none of the life has been found in the ice. Even bacteria become in-active.

To add to what Noudge79 said in #7 - if water didn't have unusual properties, getting less dense between 4°C and 0°C, and expanding on freezing, bodies of water would freeze from the bottom up. In that case, life on Earth would have evolved different from the way it has, but in what way, and whether it would have got started at all, is anybody's guess. Maybe the experts have an opinion.
