The first quality that you have to cultivate is  gratitude  to the Divine. People are thankful for even small acts of service done to them. Is it not necessary to be grateful to the Divine who has provided us with so many essential benefits through  Nature  and the five elements? The air you breathe, the water you drink, the earth on which you walk are all gifts of God.

Sri Sathya Sai Speaks, Vol 22, 1989 

Nature is the demonstrable proof for the existence of God. Members of the Sri Sathya Sai Organization have undertaken projects as a sense of gratitude to invoke a sense of spiritual connection with nature. Highway and park clean-ups, and instituting environmental programs in the communities are some of the clean-up efforts. 

Several environmental projects focus on REDUCE, REUSE, RECYCLE and RETHINK
