The Diocese of Tucson is reminding Catholics of the obligation they have to care for the planet so future generations can reap its bounty.

“This September, the pope invites all Catholics to celebrate the Season of Creation,” the diocese tweeted. “It is a time set aside to renew our commitment to taking care of the world God made for us. Recycle, plant a tree, organize a neighborhood clean-up… just a few ways you can celebrate the season!”

Pope Francis announced the Season of Creation, which goes from Sept. 1 until Oct. 4.

“May this year's theme, ‘Listen to the voice of creation,’ foster a concrete commitment in each person to take care of our common home,” he tweeted.

Catholic theology includes calling for humans to take care of all of God’s creations, flora and fauna. Many bishops and Catholic groups have praised Pope Francis for his commitment to making people more aware of their responsibility in that regard.

Pope Francis made the "Season of Creation” official in 2015 and "Statements from religious leaders around the world have also encouraged the faithful to take time to care for creation during the month-long celebration,” the Season of Creation website says. The celebration ends on Oct. 4 because that day is the feast of St. Francis of Assisi, and St. Francis dedicated his life to caring for God’s creatures and creation.

Taking care of God's Creations — the planet and all its flora and fauna — is one of the seven themes of Catholic Social Teaching, according to the U.S. Conference of Catholic Bishops (USCCB). The Catholic Church calls all of the faithful to be stewards of the earth. The USCCB acknowledges that environmental challenges include moral and ethical dimensions.

The Bible mentions the obligation throughout its text, the USCCB says. In Genesis, God creates the Earth and instructs humans to care for it. Leviticus notes that the planet should not be abused. The books of Daniel, Matthew and Romans also discuss the relationship between God and His Creation.

In Pope Francis' encyclical Laudato Si, published in 2015, the Pope described the destruction of the earth and reminded the faithful of their duty to protect it, according to the Vatican.

"The urgent challenge to protect our common home includes a concern to bring the whole human family together to seek a sustainable and integral development, for we know that things can change,” Pope Francis wrote in the encyclical. “The Creator does not abandon us; he never forsakes his loving plan or repents of having created us. Humanity still has the ability to work together in building our common home."
