Episode notes

11 of the teen calves tested work successfully toilet trained. If 80% of cow urine was collected, it would reduce ammonia omissions by 56%. And you hear a lot about the carbon footprint of animal agriculture. No, this is only a small of that footprint, but every little helps here.

How tiny seed-like sensors could monitor the environment, and the latest from the Nature Briefing.

In this episode:
