What if the earth was half water and half land?

Envision a scenario where the Earth is divided equally, with a precise 50% allocation to both continents and oceans.

Our world is divided into equal parts, with half covered by land and the other half covered by sea.

Water is important for sustaining life on a planet.

Therefore, we search for extraterrestrial life on planets that have the potential to support liquid water.

Regarding our planet, approximately 71% of its surface is encompassed by water.

The majority of that is located within our five oceans.

Collectively, they constitute a one, worldwide body of water.

If approximately 25% of Earth's ocean water were to be replaced by land, how quickly would the planet transition into a barren celestial body?

The current rise in Earth's sea levels can be attributed to global warming.

However, if you aimed to achieve equilibrium in the planet's ratio of land to water, the sea levels would experience a significant and rapid decrease.

Not only a short distance, but around 3 kilometers (1.9 miles).

The appearance of Earth would be significantly altered.

The areas surrounding both the Arctic and Antarctic poles would experience full desiccation.

Each continent on Earth would undergo expansion.

And not merely a small amount, but a significant quantity as well.

The recently emerged region worldwide would approximately match the whole surface areas of Asia, Europe, Africa, and North America combined.

That would constitute a substantial quantity of unutilized area.

All land formations that protrude from the previous shorelines would have a predominantly even and level surface.

However, certain regions that were previously submerged in the ocean would now expose extensive passageways and steep ravines.

While exploring this unfamiliar territory, you would come to realize that the existence of a single worldwide ocean would cease to exist.

Each of the oceans would become isolated from one another.

Furthermore, all the continents would form a single contiguous landmass.

This would be advantageous for the theory of evolution.

Primitive people lacked both ships and airplanes.

We expanded our presence worldwide by the simple act of walking.

Having migrated from Africa approximately 70,000 to 100,000 years ago, we successfully reached Europe and Asia.

Ultimately, we successfully traversed a terrestrial bridge that linked Asia and the Americas, maybe dating back to approximately 20,000 years ago.

By using the 50/50 divide, you will have the opportunity to cover a greater area.

Ultimately, you have the opportunity to embark on the long-awaited global journey that has always been the subject of your dreams.

Independently standing on your own feet.

However, this changing equilibrium between water and land would not solely be enjoyable and recreational.

If there were a significant reduction in the amount of water covering the surface, it would lead to the disruption of our ocean currents.

Furthermore, this would significantly disrupt the climate.

Ocean currents disperse the heat that is absorbed by the oceans across the entire planet.

Interfering with them would result in significantly lower temperatures in the Arctic and Antarctic regions.

The equatorial regions, which are already warm, would experience an increase in temperature.

Climate change would accelerate as well.

The oceans' capacity to absorb carbon dioxide from the atmosphere would be insufficient.

The surplus carbon dioxide would envelop the Earth and elevate temperatures.

Precipitation levels would also decrease.

This phenomenon would result in perilous droughts and the formation of novel desert regions in several inland locales.

Although there may be a surplus of newly accessible land, significant portions of the Earth could potentially become uninhabitable.

All organisms, including plants, animals, and people, would have to undergo adaptation in order to reduce their reliance on water.

Or, at the very least, begin utilizing it more effectively.

Water scarcity may lead to animals undergoing evolutionary changes, resulting in a reduction in size and an increased adoption of a purely carnivorous diet.

Regrettably, the current oceans' capacity to sustain a wide variety of life forms would face significant challenges in terms of survival.

One unexpected outcome that you would have to adapt to is that your urine would likely undergo permanent changes.

Typically, urine consists of over 90% water.

However, if you reduce the amount of water you use in your everyday activities, your urine would become more concentrated, resulting in a darker color and a distinct ammonia odor.

In terms of the current situation, there are more unfavorable possibilities.

You have the ability to completely deplete the oceans of their whole water content.

However, that is a narrative for another hypothetical scenario.
