Can you guess the title of my next video?

Write your guess in the comments section below.

Every year, about 8 million metric tons of
plastic waste is dumped into our oceans.

There is more plastic than planktons and krills which are a source of food for many fish.

Fish eat plastic because it breaks down into smaller fragments which are similar to the size of planktons.

In addition to this, the plastic fragments
present in salty seas or oceans.

Release odor similar to that given off by planktons.

Hence, fish mistakenly assume the plastic
fragments to be planktons and thus, eat them.

Besides this, some of these fish, even reach our table as seafood.

If we eat such fish, it can cause severe health problems.

Hence, it is very important to recycle plastic and use eco-friendly products like paper bags.

Sunburn is a term for red and inflamed skin.

It is caused by ultraviolet radiation present
in sunlight.

Sunlight consists of three types of ultraviolet radiation, UVA, UVB and UVC.

When we are in the hot sun for very long.

The UVB radiation enters into our skin cells and starts to damage the DNA.

Thus, to reduce the risk of cancer, the damaged skin cells kill themselves.

This programmed cell death is called apoptosis.

As a result, the blood flow increases to that area to heal the skin.

This leads to red and inflamed skin which
we call as sunburn.

It is because of a pigment called melanin
and ultraviolet radiation of the sun.

Millions of years ago, people living near equator received a lot of sunlight and ultraviolet radiation.

Now, ultraviolet radiation is actually absorbed by our skin to produce Vitamin D.

But excess radiation can damage our skin cells.

Hence, the skin of these people produced more melanin to block the excess ultraviolet radiation.

These people and their succeeding generations adapted to have a higher level of melanin in their skin

However, people living away from equator received less sunlight and less ultraviolet radiation.

Hence, in order to absorb sufficient ultraviolet radiation and produce the essential Vitamin D.

These people and their following generations adapted to have a lower level of melanin.

We shiver because our body tries to keep us warm.

Our core body temperature is about 37 degrees Celsius or 98.6 degrees Fahrenheit.

A part of our brain called hypothalamus controls and maintains the core body temperature.

Usually during cold months, the temperature is quite low.

Hence, if we have not worn any warm clothes, we feel cold.

This decrease in temperature is instantly
detected by our hypothalamus.

Thus, it sends signals to our muscles to contract and relax rapidly, making us shiver.

This rapid contraction and relax of our muscles generates heat.

This heat warms our body, thus helping us
maintain our core body temperature.

Earthing is the process of transferring charge from a charged object to the earth.

It is done with the help of this lightning
rod.

A lightning rod is a metal rod whose lower end is fixed to a copper plate buried deep in the earth while upper end has spikes.

This is because it protects us from lightning.

It can damage an entire building and harm
the people living in it.

The lightning rod transfers the massive charge from the lightning to the earth safely.
