Cars and transport, and the gases and particulates that they emit from their exhausts have a serious effect on the environment and on human health.
In the future the transport system will have to look very different.
For example, in the UK there could be
three times as many journeys using electric buses rather than using bicycles
and two times as many journeys using bicycles than using private electric cars.
For the people in the UK write down the ratio of journeys using electric buses to bicycles to private electric cars.
