A sheep eats grass on a Welsh hillside where nothing else will grow.
In return it provides:
- Wool (renewable clothing that biodegrades)
- Meat (complete nutrition)
- Lanolin (waterproofing, cosmetics, leather conditioning)
- Sheepskin (insulation, clothing, rugs)
- Bones (tools, broth, fertilizer)
- Manure (soil building)
All from grass on terrain too steep for tractors.
The environmental alternative is petroleum-based fleece that sheds microplastics, synthetic insulation made from fossil fuels, and importing food from industrial agriculture that destroys prime farmland.
But the sheep grazing on a cliff is the problem.
Make it make sense.
