Many people think that recycling is a new thing, but in fact,
humans used to recycle things in 400 B.C.! Scientists recently used
to discover that people in Turkey reused glass. Later, in 1031, the
Japanese used to start recycling paper.
In times when people were poor, they didn't used to throw things
away. Just before the industrial revolution (1760-1830), people use
to melt and recycle metals. But during the industrial revolution,
things suddenly became cheaper and easier to make, so there was
less recycling.
Nowadays we recycle because we know more about
environmental problems. So while your grandparents used to
recycled because they had to, we now recycle because we should.
