About 150 years ago the air was pure and clean.
Слайд 3
Then people started building factories and many
of the things they make, like cars, put a
lot of harmful gases into the air.
Слайд 5
Many cities around the world have air polluted
with “smog”. This is so strong in some places
that the air, which should be a beautiful blue, looks brown.Слайд 6 The planet Earth is mostly water. Oceans cover

Слайд 14
If we recycle and reject we will produce
