Hindu Family and Nature preservation

In our country Bharat we have hindu philosophy to preserve atmosphere(paryavaran). We have family tradition and value to have harmony in all human beings, creatures, plants and non living things too i.c Ekatma  Manav Darshan.We are tought in family how to preserve mother earth and all elements of nature.I do remmeber one event, Subramanyam shatri of Andhra pradesh RSS told that when he was child, was used to take away mangoes from his own house mango trree. At that time grandmother was telling to him , not to remove all mangoes, just keep few for birds coming to tree. As a child ,he has to argue that even if we try to remove all mangoes, it is difficult, we can not remove all, still few will remain which are hiding in leaves or which are at top, where difficult to climb.Those can be eaten by birds. Gran mother answer was , this PUNYA goes to tree, not to us. This is how hindu family was preserving PARYAVARAN.
