2. Natural rubber has been replaced by many new synthetic materials.
Natural rubber, though, is
still used in tires,
electrical insulation, and for waterproofing. Natural rubber is made from latex,
which comes from rubber trees. Latex is a milky liquid.
To gather latex, workers must be hired and
then they make shallow cuts in the trunks of rubber trees to gather the latex.
They attach a spout to
the tree and a small cup. The cup is used to collect the latex. Removing the latex does not hurt the
tree. Latex is not the sap of the tree. One worker can tap as many as 350 trees each day.
