Problem/ solution paragraph

In recent years pollution has been constantly increasing. This pollution is mainly caused by human activities which affect the natural environment by producing toxic emissions and fumes.

 It is driving cars one of the most contaminating activities that take place nowadays. Cars pollute the air with particles that damage human breathing. A solution that could be extremely effective would be reducing the use of cars by means of promoting the use public transport instead so that people could easily move around the city. However sometimes you do not dispose of time enough to wait for the tram or the bus and that is the reason why the bus line should be modified, just to enable more buses to circulate.

If the amount of buses increase, pollution will also do. People could take advantage of it by using more electric buses. By this way people would be able to reduce contamination in a short period of time.
