Quaker work on the environment centres on the increasingly evident need to take care of our planet and its resources for the sake of future generations. Contemporary Friends are much more aware of the finite nature of the Earth's resources than were earlier generations, and environmental concerns have a much higher profile now than in the past.
All the five original testimonies lead to it - simplicity (using only what you really need), peace (minimising the risk of conflict over resources), integrity (recognising and acting on the needs now we understand them), community (thinking of others, both now and in the future, and everywhere in the world) and equality (fair and equal treatment for present and future generations). Due to its increasing importance, it is increasingly seen as a sixth testimony, as in the SPICES formulation.
