Nature The prime Guru

Yes... we need to tell yes for this we humans trying to copy the nature from the times our brain started working. But we got little and spoiled many in the nature. Even though we have a hope at a corner to make this nature as it was. we will always fail until we don,t leave the luxury and selfishness. i hope we will get our aim and need will get manifest soon...............

Indians introduced activated carbon filtration

It was mentioned that ancient Indians used activated carbon for water purification. they prepared activated charcoal from coconut shells, tamarind shells etc. Recently it was re-searched that activated charcoal from tamarind shells was used for removal of fluoride and +6 chromium. I hope it was already known to our great ancient Indians.
