Greetings teacher and friend @amestyj

Excellent topic, it is deduced, that the global heating is the responsible for the appearance of pandemics, therefore the COVID-19 is direct consequence of the greenhouse effect that affects the ecosystems of the planet, certainly the cattle activity is a sector that contributes gases of greenhouse effect mainly due to the methods of handling of the flock that generate these imbalances, your proposal to let them consume grasses to will or of natural way, in effect would avoid to create these high production of methane gas in the cattle units.
