This is not about having a pet sheep, or sheep in the meadow near your house. This is about using sheep wool to insulate your house. In Buenos Aires, an architecture firm designed a very sleek house and instead of using other materials to insulate and keep the house cozy and warm, they selected to use wool from sheep. This same wool is used to make your cozy and warm sweater and blankets on your bed.
DUB Arquitectura is the firm and they made this environmentally sound choice when they designed this house. We need more good ideas like this moving forward to protect the planet.
