| Every day, all over the world people
are travelling. People travel to work and school, to visit their friends
and family and to see new places and new countries. Farmed and manufactured
products are also constantly being transported from one place to another
everywhere. There are lots of different modes of transport that are used
to transport people and goods to places around the world - cars, lorries,
buses, trains, aeroplanes, coaches, boats, ships, bicycles and our feet!
Forms of transport that are powered by petrol or diesel can cause pollution
because they produce carbon dioxide when they are burnt by the engines
of the cars, buses, or lorries. Some buses and trains are powered by electricity
which produces less pollution than petrol and diesel. |
