Paper is very important in our lives. We use paper to write, print, decorate, make books, make money and many other things.
Paper is very old. Chinese people made papers 2000 years ago.
Basically, paper comes from trees. We can make different types of papers depending on the characteristics of the trees: trees species, climate and geographic location.
Trees living in cold climates are very strong because they grow very slowly. We can use these types of trees to make newspapers – the pine tree is a good example of a strong tree.
Other tree species are not very strong, for example, eucalyptus, and we cannot use them many industrial applications.
Paper can be recycled many times depending on the type of paper. But when paper is contaminated with chemicals, it is more difficult to recycle.
Today on our planet, 30 per cent of paper fibres come from recyclated paper and cardboard.
