What if earth lost Oxygen for 5 seconds? | #aumsum

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.
