about 15 years ago once I was stuck for few days in the north side of Salang pass which connects Kabul to north of Afghanistan. there was raining and storm. after few days the clouds disappeared and sun was shining. suddenly thousands of this thin worm; exactly like as they are in the pictures, appeared every where. they were very dry and rigid.
This is a sad news indeed and human is responsible for this and all environment destruction. One day our mother planet (earth) will get the revenge of all these destruction from mankind. I hope before that day the humans will learn that this world is not only for them.
