Here is the link to Pope Francis’ Encyclical, “Laudato Si'” which in some ways provides the most recent update to a growing strain of the social doctrine of the Church on the question of our responsibility for the environment:
The Encyclical is rather long, but wikipedia offers a useful summary of its contents and of its impact: https://en.wikipedia.org/wiki/Laudato_si%27
You may also find this link useful to break the Encyclical down as a way of more easily understanding it:
2020 marks the 5th anniversary of this Encyclical and the Vatican has established this year as a Special Anniversary Year.

There is a website specifically dedicated to this anniversary year: https://laudatosiyear.org
