Ice-age

So talking on climate changes,

It's not a thing we are facing for the first time.

.

Earth has already seen 5 ice-ages

And cooling down of environment

Is a periodic event of Earth.

.

This lead to many extinctions too,

Usually of clood blooded animals.

.

We are currently living  in 

The 5th inter-glaciation phase of Earth.

.

What we don't realise is 

The 6TH GLACIATION COULD OCCUR ANYTIME

.

Human interference has been contributing so much to the climate changes

And has made it impossible to foreshadow the time period of glaciation.

.

It might LEAD TO OUR EXTINCTION too.

.

We cannot prevent glaciation,

But if we act with a little more consciousness

We could protect ourselves during that phase of Earth's climate.
