Comment: All well and good. The meat industry is also one of the main drivers of climate change. Laudato Si does not even mention it. Would be good to see some action from Catholic groups on that front. It's not only about fossil fuels.  The meat industry is the world's largest polluter (responsible for 51% of greenhouse gases, according to some reports). The leading cause of rainforest destruction, species extinction, ocean dead zones and water pollution is not fossil fuels, but raising animals for food. "Livestock" produce more greenhouse gases than all the world's cars, trucks, boats, planes and trains combined. To stop climate change we need trees, but 90% of Amazon destruction is for animal agriculture. 45% of earth's ice-free land is occupied by animal agriculture, with free-living animals being squeezed out of their habitat all the time. 30% of all water consumed is for animal agriculture. Almost 50% of the world's grain is fed to "livestock," yet a billion people go hungry every day.
