air pollution in mexico city
this is crazy
about mexico city and their problem
sometimes they can not drive their cars because the pollution is so horrible.
people have to encourage the citizens to ride the bus.
this can be a hazardous thing to the children
they might get lung problems
why is this happening
dude wat da crap
it is happening because of all the trucks and cars
it is also happening because of factories
hopefully this will get better in mexico
this could cause the city to go somewhere else
this can probably make the citizens to stop
