Pope Francis launched Tuesday the Vatican’s seven-year Laudato si’ action plan to implement environmental sustainability in different sectors of the Church from religious orders to Catholic schools and hospitals.

“We need a new ecological approach that can transform our way of dwelling in the world, our styles of life, our relationship with the resources of the Earth and, in general, our way of looking at humanity and of living life,” Pope Francis said in a video message May 24.

The pope marked the end of the year celebrating the fifth anniversary of his environmental encyclical Laudato si’ with the message announcing the initiative.

He said that the year would be followed immediately by a seven-year plan known as the Laudato si’ Action Platform.

The Laudato si’ Action Platform will focus on seven sectors: families, parishes, schools, hospitals, businesses, organizations, and religious orders.

The pope explained that the action plan also has seven goals: the response to the cry of the earth, the response to the cry of the poor, ecological economics, adoption of simple lifestyles, ecological education, ecological spirituality, and community involvement.

“Our selfishness, our indifference and our irresponsible ways are threatening the future of our children,” Pope Francis said.

“I therefore renew my appeal: let us take care of our mother Earth … let us overcome the temptation of selfishness that makes us predators of resources, let us cultivate respect for the gifts of the Earth and creation, let us inaugurate a lifestyle and a society that is finally eco-sustainable.”
