EXCITING AND INFORMATIVE: Do you know this about INSECTS?

Hi folks todays post is really astonishing and informative so without any due lets start.
350 million years ago our EARTH is so different from what we see today on GOOGLE EARTH.It has different forms in different period of time.The EARTH's age was around 4 billions years even stars were so different at that time.The giant dinosaurs were not there they arrive 100 millions years after that period at that time birds were not there nor flowers the air was also different from now..jpg)

The ENVIRONMENT at that time has huge amount of oxygen which is never found ever on planet again.Because of these only the INSECTS were huge in size,but how because insects dont have lungs like us.The life surviving oxygen goes into the insects through small pores present on there body and spread through the tube webs. If insects grows bigger the oxygen gets absorbed in those tubes present on surface of insects and cant reach to inside parts of insects.This period is known as CARBONIFEROUS PERIOD where oxygen level is doubled from which is present on earth today, that causes the insects to grow bigger .This oxygen rich environment help the insects to develop in huge sizes.
HERE COMES THE intresting part of article with some facts the DRAGONFLY WERE AS LARGE AS KITE and MILIPEDES WERE AS HUGE AS ALIGATORS even the SCORPIANS grow upto the scale of 70 centimeters which is very hard for us to believe.
This all was possible because of science.In todays world we used to crush the insects but think of that time what would be our reactions to see those gigantic insects in huge number same as we found today.The only thing i want to reflect here is not everyone remains same for whole life today we think we are great species living on planet and scientist think next big thing surviving on this planet earth would be those arthropodas only.
HOPE BEST FOR ALL THE LIVING AND NON LIVING PART OF EARTH.
THANKS
