In my view there are a number of actions that could be taken. With the first problem, the
easiest way to work it out would
to develop new technology for car engines which doesn’t
cause serious air pollution, like some kind of exhaust filters.
Taking on the second problem, the
most successful way to confront this would be
to invest heavily on research on alternative
energy sources.
In fact,
I recently read an article at a blog that humans have already produced
cars which use water instead of gasoline to run.

become in the Speaking Interview. This is a fact. Good luck.
