“Much of the oxygen we breathe comes from plants that died long ago. We can give thanks to these ancestors of our present-pay foliage, but we can't give back to them. We can, however, give forward. When we are unable to return the favor, we can pay it forward to someone or something else. Using this approach, we can see ourselves as part of a larger flow of giving and receiving throughout time. Receiving from the past, we can give to the future. When tackling issues such as climate change, the stance of gratitude is a refreshing alternative to guilt or fear as a source of motivation.”
