Air pollution
Highway congestion
Air pollution has caused it because the engine of the cars has made the smell of the air be not very nice, and people could end up being ill because of having to breathe in petrol, because they might have an allergen.
Highway congestion because there are so many cars these days, that most of the time you go on a highway (motorway), there are loads of cars queueing. This can also cause air pollution because the animals that might be in a field at the side of the motorway won't like the smell of all those cars.
A reform movement is a type of social movement that aims to bring a social or political system closer to the community's ideal. A reform movement is distinguished from more radical social movements such as revolutionary movements which reject those old ideals in the ideas are often grounded in liberalism, although they may be rooted in socialist (specifically, social democratic) or religious concepts. Some rely on personal transformation; others rely on small collectives, such as Mahatma Gandhi's spinning wheel and the self-sustaining village economy, as a mode of social change. Reactionary movements, which can arise against any of these, attempt to put things back the way they were before any successes the new reform movement(s) enjoyed, or to prevent any such successes.
