Kids planted over 70 trees at our colony. They have formed a group called ecoLife. Target is to plant 2000 trees with 200 different varieties. Tree Diversity they call.
Ecolife started small , 3 of them and now it is a group of 20. Every week ecolife tries to plant 10 saplings. Perhaps, each colony can form a small kids group and plant 3 saplings a month. Then , in a year we would see 36 trees in a street!.
