  • It's AumSum Time.

  • What if earth lost oxygen for 5 seconds?

  • We would need to organize a search party.

  • No.

  • If it was just 5 seconds.

  • We wouldn't notice changes in our breathing.

  • But do you know what would happen around us?

  • Earth's crust contains 45% oxygen.

  • Without oxygen, crust would crumble.

  • Causing the ground to crumble and we would be in freefall.

  • Buildings, bridges and concrete structures would crumble into dust.

  • As oxygen is the binding agent for concrete.

  • Cars would stop.

  • And planes would fall from sky as their combustion engines wouldn't work without oxygen.

  • Also, losing oxygen means losing almost 21% air pressure.

  • This would cause our inner ear to explode, causing hearing loss.

  • It would also become darker suddenly.

  • Why?

  • For sunlight to reach us, it needs to bounce off air particles like oxygen, dust etc.

  • No oxygen means much fewer particles to bounce off, thus much darker.

  • Can pure oxygen kill you?

  • No idea.

  • The air we breathe has many gases out of which 21% is oxygen.

  • When we inhale.

  • Much of the oxygen present in air binds to the hemoglobin in red blood cells.

  • And is transported to various cells where it helps to produce energy.

  • However, some inhaled oxygen also turns into free radicals.

  • Free radicals are highly unstable and can be harmful.

  • Hence, our body produces antioxidants that neutralize the free radicals.

  • But if we inhale pure oxygen for a long time, then the number of free radicals increases.

  • It becomes difficult for the antioxidants to neutralize them.

  • Hence, these unstable free radicals begin to bind with proteins in red blood cells.

  • And change their chemical structure.

  • As a result.

  • Our immune system doesn't recognize the red blood cells and begins to kill them.

  • Besides this, free radicals even damage the DNA which can lead to cancer.

  • Earthquakes.

  • What causes earthquakes?

  • I, me and myself.

  • Ya ya.

  • You show off.

  • An earthquake is violent shaking of the earth's crust.

  • The earth's crust is a hard outer covering made up of many pieces called tectonic plates.

  • These plates are always moving.

  • However, the motion is very slow.

  • In a year, they move only 2 to 5 cm.

  • Hahaha.

  • My hair grows faster than their movements.

  • Absolutely.

  • Mostly when these tectonic plates move.

  • They brush against each other without causing great damage.

  • However, sometimes they get stuck and cannot easily slide against each other.

  • But the plates still keep pushing, thus creating pressure.

  • Eventually.

  • The pressure builds up so much that one of the plates suddenly moves above the other.

  • Or they may crash into each other, causing the crust to shake violently.

  • Thus creating an earthquake.

  • How big is the Great Pacific Garbage Patch?

  • It can't be bigger than me.

  • Oh.

  • You're unbelievable.

  • Every year, we dump around 8 million tonnes of plastic waste in the oceans.

  • Now, since plastic doesn't degrade easily.

  • It keeps floating in the oceans for hundreds of years.

  • Overtime.

  • Strong winds and natural ocean currents cause this plastic to gather.

  • In five massive garbage patches.

  • The biggest garbage patch of them all is the Great Pacific Garbage Patch or GPGP.

  • It is in the Pacific Ocean between Hawaii and California.

  • According to estimations, nearly 1.8 trillion plastic pieces are floating in the GPGP.

  • Which weigh about 90,000 tonnes.

  • Also, some people say that the GPGP is twice the size of Texas.

  • Environmentalists are actively trying to develop alternatives for plastic.

  • We should also contribute and reduce its use.
