What if we had no Moon?

The Moon is a giant rock that lights up our night and can even change colours.
So what would we do without it? Would we all need night vision goggles? And how would it affect the Ocean tides? Or Our Seasons? Or our Sleep Cycle?

 As the closest celestial body to our planet, the moon exerts a gravitational pull that governs much what happens on Earth.

Take the example of the sea. If you love surfing, then thank the moon. When the moon's gravitational pull tugs on our spinning earth, the oceans respond, giving us high tides in some parts of the world, and low tides elsewhere. And while the winds give their waves the energy, tides define their shape.

The moon's gravitational attraction also keeps us stable 23.5-degree tilt relative to the sun, giving us 4 seasons and the livable climate. But have you ever thought about if the livable climate becomes unlivable? What will we all do then?

When the moon is gone, its stabilising effect on earth will also go with it. Want a good news? The weekend will get a hell lot closer.
If the moon is gone, then a day on earth will be just 6-8 hours long.

Over million years, shifting ides and their pressure on earth's continents have slowed our planet rotations, giving us 24 hours day. But without the moon strong gravitational influence, the world would spin 3-4 times faster then it currently does.

Here comes the bad news.

Rotating at that speed, we will experience wind speed of up to 480 Km/hour (300mph). Birds and insects will have no chance of survival. The luckiest land-based organisms would either be deeply rooted plants or very short, very stout animals.

Most of our marine life will be wiped out since sea creatures that rely on ocean current for survival would lose the privilege of ocean's pull. Currents help to circulate vital health nutrients from the ocean floor to the surface while dragging oxygen-rich surface water to the deep sea.

We'd still have tides, but now they will be governed by the sun. And from the distance of 93 million miles away, they'd only be one third as powerful. And with the moon out of the scene, the ocean would rip towards the sun creating catastrophic waves, killing thousands and submerging coastline.

At this point, we'd have to adjust to new ocean currents, which, circulating at a lower rate, would be heating up equatorial waters while turning polar waters frigid.

These extreme differences will produce same effects on land since ocean temperatures influence their regional climates. Along with the sun, mars and other nearby planets could also claim their share of gravitational influence over our planet, pulling earth in different directions, and causing it to tilt with extreme volatility.

Earth's axial plane will vary around 10 degrees causing a dramatic shift in seasons and rendering our climate inhabitable. Most crops will die with drastic climate change and we'd experience worst ice-age phase known to man.

So while full moons may attract werewolves, that's still better than an alternative world where there is no moon
