Stuff you never think about

 Corks!!!!

 

 Wine corks are a stopper used to seal wine bottles. They are typically made from cork (bark of the cork oak). Half of the world's cork wine stoppers come from Portugal's cork oak trees. These trees are so important to the country's ecosystem and economy, they're protected under Portuguese law.Go inside the forests of Alentejo to see how the cork bark is carefully harvested every nine years so it doesn't hurt the trees.
