1. Waste: Uncovering the Global Food Scandal -by- Tristram Stuart (this about food waste in UK)
2. Our Environment -by- Laeeq Futehally (this is on Indian environment)
Applicable for all ages, both offers important yet unknown pointers for our action and non-action wrt. many things.
I have a huge list that covers over 100 books and over 200 documentaries and films on various subjects from Organic Agriculture, Environment, Rural life, Home schooling, Psychology, Pedagogy, Spirituality, Science, etc., would too big to put in here... Hopefully some day I'll be able to get these and read and also put-up a library
