Smog can be decreased by limiting those processes that create it. In the United States, where huge amounts of smog are produced, action is being taken to reduce smog levels.
Governments are combating smog in several ways. Laws are
encouraging producers of automobiles to develop cars that produce less smog, and chemical companies are being watched over and restricted from producing certain harmful substances.
In addition to national solutions which often deal with large plants that produce smog, local and individual efforts are underway as well.
Many communities and their governments are attempting to restrict usage of dangerous products such as barbecues, house paint, and kitchen cleaners.
In Denver, Colorado,
the second most polluted US city after Los Angeles, several innovative measures have been taken in an attempt to decrease smog. The government has requested that people not drive to work at least one day a week, encouraged use of oxygenated fuels, and experimented with fuels that create less smog.
Not to be outdone, Los Angeles' city council came up with a long list of measures aimed at reducing smog. They decided to require carpooling, offer free bus services, and create many
environmentally-friendly regulations for homes.
Research is being done to find less harmful alternatives for many smog-producing processes. Scientists and corporations are testing new fuels from new sources and trying to replace other products that create problems as well.
In the future, many cities and countries will realize that they need to follow the examples set by cities like Denver and Los Angeles. Hopefully, they will not have to acquire those cities' high
smog levels before taking action.
