September 1 is the World Day of Prayer for Creation and the start of the Season of Creation.
This day of prayer was established by Patriarch Dimitrios I for the Orthodox in 1989, and was  then embraced by major Christian European churches in 2001 and by Pope Francis for the Roman Catholic Church in 2015.
Pope Francis has issued a new statement for the day of prayer, calling for a “renewed and sound relationship between humanity and creation” and asking us to pay special attention to the issue of water.
Today, Christians around the world unite to pray as one. We invite you to pray this prayer from Laudato Si’.
A Prayer for Our Earth
All-powerful God, you are present in the whole universe
and in the smallest of your creatures.
You embrace with your tenderness all that exists.
Pour out upon us the power of your love,
that we may protect life and beauty.
Fill us with peace, that we may live
as brothers and sisters, harming no one.
O God of the poor,
help us to rescue the abandoned and forgotten of this earth,
so precious in your eyes.
Bring healing to our lives,
that we may protect the world and not prey on it,
that we may sow beauty, not pollution and destruction.
Touch the hearts
of those who look only for gain
at the expense of the poor and the earth.
Teach us to discover the worth of each thing,
to be filled with awe and contemplation,
to recognize that we are profoundly united
with every creature
as we journey towards your infinite light.
We thank you for being with us each day.
Encourage us, we pray, in our struggle
for justice, love and peace.
