Green technologies cannot develop
fast enough as major cities around the world are dealing with the negative
effects of pollution. High economic activity in many major cities is leading to
increased air pollution. It has even gotten so bad that in the city of
Shanghai, public transit drivers are getting lost on their daily routes due to smog
coverage. What is the point of continuing economic growth in these areas if
the health of the local environment deems the area unlivable? As the human
population continues to grow and become more urbanized, personal as well as
environmental health will become more of an issue.
China
seems to get the heat for being one of the worlds worst contributors to air
pollution. Although some major cities in China (Beijing and Shanghai) do show aggressively
high levels of particulate matter in the air, New Delhi ( in India) takes the
cake. A recent measurement of this particulate
matter in the air put New Delhi’s average daily peak reading at more than
twice as much as Beijing’s. The focus may be stuck on China for now, but other
major cities throughout the world are experiencing the same air quality issues.
India has even been reported to have the world’s highest death rate due to
chronic respiratory
diseases. This particulate matter can make its way into lungs and degrade
human health. Asthma is only one example of the many diseases caused by air
pollution. A sad truth lies in the fact that both China and India were very
resistant on setting lowered pollution limits in global
climate talks. These countries are showing their reluctance on taking
proactive and reactive steps to better the quality of life in these areas.
Another
issue that causes a decrease in air quality is trans-pacific and
intercontinental air
pollution. These types of air pollution will effect neighboring
cities/states/countries of highly polluted areas as typical wind patterns carry
bad air downstream. An example of trans-pacific air pollution can be found as
the westerlies
(northern hemisphere wind pattern) carry dangerous pollutants from a polluted
China to the west coast of the United States. The United States, however,
cannot act completely innocent as we outsource
a lot of our products from China. The east coast of the United States can also
serve as a victim to downstream
air pollution as the Midwest continues to burn coal mercilessly. Some
states in the Midwest seem to have more lenient emission regulations as
compared to eastern states such as Connecticut and New Jersey who are
experiencing these down-wind pollution effects. Current petitions
are going out in an effort to halt some of these negative externalities faced
by eastern states. Wind borne air pollution may be a global wake up call to
curb carbon emissions.
Resistance
to cutting back on carbon emissions is beginning to meet its match. In Paris,
France, police began pulling over vehicle’s with even number license plates and
fined
them an equivalence of 31 U.S dollars. Police will continue the enforcement of
this new law in an effort to show citizens their effect on the environment.
There are some exceptions
to this law, which include individuals using hybrid vehicles, vehicles with
three or more people, and motorcycles. These efforts need to be implemented
throughout the world in cities facing dangerous levels of particulate matter in
the air. As human population growth shows its devastating effects on all
aspects of the environment, air pollution seems to be one of the most evident
problems. Without action to combat our environmentally unsafe practices, human
health on a global scale will take a hit.
In Environmental Science Seminar this evening we were talking about efforts in the U.S. and China to reduce traffic congestion, and thus decrease traffic pollution, by renovating cities with more and better bike lanes and public transit options. Usage of public transit is trending upwards in big cities like LA (subway usage up 4.8% in 2013) and in smaller cities like Cleveland (2.9%).
