Um,Mummy,why did you say that we need to think about the way we travel?
Because it is hurting the world.
And if we carry on travel on our own, things could get worse and worse,
But, my teacher also says, if we travel together, things could get better and better.

Choose public transport, and help to rece the carbon emissions and contribute to climate change, the world is your home, look after it.
