Nature has given direction to us but do we follow
In many places, people cut the trees as they feel they are not required to them or feel hindrance to them for their movement. But they do not think that such action is against nature. To prevent them there are stories through epics etc., in the form of sin etc. But we people do not care on such things by seeing this and that. Because of the absence of trees in our cities and other places the pollution become bad and air is felt so hot and it is leading to many diseases thereby.Nature gives many indications and alerts but we do not notice them carefully.
An example I have seen yesterday-
We used to see in packed foods packets etc a mark or line have given for tearing. Similarly I have seen when plucking flowers for daily pooja in our garden, I casually noticed that the hibiscus flower has a small line mark in its stem and it denotes that we can pluck the flower from that line easily.
