Activist: "You're using an obscene amount of water."

Farmer: "Am I?"
Activist: "Yes. Thousands of litres per cow."
Farmer: "That's rainfall."
Activist: "But they're drinking it."
Farmer: "It rains on my pasture. The grass absorbs it. The cows drink from the stream. Then they piss it back into the soil."
Activist: "It's still water consumption."
Farmer: "Should I... stop the rain?"
Activist: "You should use it for crops."
Farmer: "The rain?"
Activist: "Yes."
Farmer: "The rain that falls on the grass that cows eat?"
Activist: "Grow crops instead."
Farmer: "With what irrigation? I just told you it's rainfall."
Activist: "Find another way."
Farmer: "To make it rain on crops instead of grass?"
