Stewardship is a theological belief that humans are responsible for the world, humanity, and the gifts and resources that they have been entrusted. Believers in stewardship are usually people who believe in one God who created the universe and all that is within it, also believing that they must take care of creation and look after it. Creation includes animals and the environment. Many religions and denominations have various degrees of support for environmental stewardship. It can have political implications, such as in Christian democracy.
Many moderate and progressive Roman Catholics, Orthodox Christians, and Evangelical Protestants see some form of environmentalism as a consequence of stewardship. In Jewish, Christian and Muslim traditions, stewardship refers to the way time, talents, material possessions, or wealth are used or given for the service of God. Some pagan or secular views include a Gaia philosophy which accepts the Earth as a holy being or goddess. The Jewish holiday of Tu Bishvat, or "the New Year of the Trees" (Rosh Hashanah La-Ilanot"), is also known as Jewish Arbor Day. Some want to expand it to a more global environmental focus.
