Earth Day bears us to recall what Pope Benedict XVI said:

“On this earth there is room for everyone: here the entire human family must find the resources to live with dignity, through the help of nature itself — God’s gift to his children — and through hard work and creativity. At the same time we must recognize our grave duty to hand the earth on to future generations in such a condition that they too can worthily inhabit it and continue to cultivate it… One of the greatest challenges facing the economy is to achieve the most efficient use — not abuse — of natural resources.”

(Caritas in Veritate, 50)
