If land covered 72% of earth?

Question

If land covered 72% of earth?? what type of circumstances we would have here? like would the pollution levels be the same as now? Population? what about the water resources and natural resources?? whats ur view on that.

Answer 1

I think it would depend very much on how water and land was divided. If it was one big continent, there wouldn't be much life to sustain in the middle of it. It it was a lot of small islands, life would be easier, maybe not much different from now.
I would think that the average temperature would still be as it is now: 15° centigrade. It means that the air over the water would still contain 14 grams per cubic meter to be saturated. It would still be colder in altitude and that would still form clouds that would fall down as rain. But that would be mostly along the coast; hence the need for a long shoreline.
Away from it, the days will be warmer and the nights colder, just as it is now in places like the deserts.
Low pressures would be less violent because there would be less humidity to 'feed' the uneven adiabatic cooling between saturated and unsaturated air.
In any case, I'd try to find a home near the sea, even if it will probably be overpopulated. Of course, the total population would be less than it is today but ... most of our environmental problems today come from overpopulation.

Answer 2

We would be very thirsty and probably not have the same weather patterns Maybe no rain at all. and possible no life at all. The oceans provide us with the wealth of and diversity of life we know today with out it there would possibly be no humans.
