What if earth was half land and half water

On our beloved planet Earth, water is ubiquitous, found not only in oceans and seas but also in the atmosphere, the ground, and even within our cells. It covers a staggering 71% of the Earth's surface. One might wonder if our planet should have been named "Water" instead of "Earth." However, let's explore what would occur if water and land were distributed equally, with half the planet being land and the other half water.

Firstly, it's crucial to clarify what is meant by "equally." Despite water's omnipresence, it constitutes only a small fraction of Earth's total mass—0.02%, to be precise. If evenly distributed, we would have a planet dominated by an expansive ocean, with minimal landmass. This ocean planet would present numerous challenges for life.

The entire surface would be shrouded in thick fog and clouds, creating a perpetual, impenetrable haze. Sunlight would be obscured, making it impossible to discern day from night. Navigating such a world would be exceptionally difficult due to the high humidity, where the boundaries between water and air blur.

The ocean itself would pose significant challenges for life. The seabed, located beneath miles of water, would consist mainly of hard, impenetrable ice variants like ice 5 and ice 6. Life forms would need to withstand immense pressure, exceeding 20,000 Earth atmospheres. While theoretically, humans could establish giant underwater stations, the practicality of survival, resource acquisition, and maintenance would remain formidable obstacles.

Now, considering another scenario—what if Earth's surface were divided equally between water and land? To achieve this, reducing the current water coverage from 71% to 50% would result in a drop in sea levels by approximately 2 miles. Such a shift would lead to catastrophic consequences.

The five interconnected oceans—Atlantic, Indian, Pacific, Southern, and Arctic—would transform into separate closed reservoirs. Continents would merge into an enormous landmass, reminiscent of swapping land for water. While it might initially seem intriguing to be able to walk around the world, the repercussions would be severe.

Disruption of ocean currents would cause drastic climate problems. Earth's temperatures would become more extreme, with heightened heat near the equator and increased coldness at the poles. Antarctic ice would not serve as a saving grace; instead, regions around the North and South Poles would transform into dry, cold deserts.

Moreover, the absence of water absorption by oceans would lead to the accumulation of carbon dioxide in the atmosphere, resulting in rising temperatures, planetary dryness, and increased forest fires. Precipitation levels would decline, leading to widespread droughts and the emergence of new deserts across continents.

Although new territories would emerge, the loss of forests, plants, and migration of animals to more habitable areas would render many regions uninhabitable. The scarcity of resources would force rapid evolution and adaptation for all life forms, with potential shifts in size and diet for animals.

Humans would face setbacks, losing access to hydroelectric power and experiencing a regression in evolution due to resource scarcity. The resulting crises would have profound implications for societies worldwide. In conclusion, the current balance of water and land on Earth appears to be the optimal scenario, and it emphasizes the importance of preserving our planet's existing conditions.
