In
todays world it has become normal to have any food available to you at any time
of the year. Most of this food is not locally produced. The food comes from
around the world to the shelves of your local supermarket. The cost of shipping
oranges from Florida, Cod from Norway and lemons from Argentina is horrendous.
The amount of greenhouse gasses that are blasted into the atmosphere transporting
food is unacceptable and if we keep at it soon there will not be much left of
our precious home. We have to learn to produce and eat our local food even if
that means not every kind of food is always available to us at all times.
Sure it is convenient to always be
able to eat what you want, but what is the cost? Until recently, it was cheaper
to grow and sell food locally because resources such as overnight shipping from
one end of the earth to the other were not an option. Now, with globalization
at its peak, it is cheaper to pay laborers in poor countries sometimes as
little as a penny a day to grow food and then ship it half way around the world
to sell it to the rich countries. If we grew and sold our food locally we could
boost our economy by providing jobs for a lot of people on farms and
drastically cut back on our impact on the environment because there would be no
need for everything to be shipped long distance.
It is ironic, that California, which
exports a lot of food, also imports so much of it. In 2005 more then three
million tons of fruits, vegetables, nuts, and wine were imported from places
like Australia, the Netherlands and New Zealand. All of this food came through
ports like Oakland. In fact, these ports experience so much traffic that higher
pollution levels have been noticed in their vicinity. The results are an
increase in health problems like asthma. The highly increased levels of diesel
soot in the air cause the effects. The amount of Diesel fumes that are produced
by these ports can be so great that the health risks involved with living near
one of these giant ports are unacceptable. The California Air Resources Board
estimated that in 2005, 2,400 early deaths and 2,800 hospitalizations for
asthma and other diseases were sourced to exposure to diesel pollution from
freight transport activities within California. Approximately 950 cases of
asthma, 16,870 missed schools days, 43 hospital admissions, and 37 premature
deaths could be linked to the worsened air quality from food imports in 2005. (Food
Hub).
However, there are exceptions to our
shipping fiasco. Sometimes it may actually be less harmful to grow certain
products like rare exotic flowers in tropical locations and then ship them,
rather then growing them in power hungry greenhouses that suck horrendous
amounts of power to produce light and heat every day. The cost of keeping a
greenhouse lit and heated for the entire duration of the life of a plant is
much more costly in terms of pollution then it is to let the flower grow
naturally and then send it to where it is wanted. (Elizabeth Rosenthal). The
question is: do we really need things like tropical flowers in our house when
there are flowers that could be grown locally? We’ve made it through our entire
history without them, so I think we would be just fine without them. But aside
from these few and rare exceptions the impact of shipping greatly outweighs the
cost of growing locally. The amount of greenhouse gases that could be saved
from going into the atmosphere by cutting down on shipping is huge, and if it
were less, our planet would greatly appreciate it.
The European union recently raised
their tax on imported food by twenty percent in order to encourage more
domestic food production. I believe this is a step in the right direction, if
imported food weren’t so cheap everywhere, people would be less inclined to buy
it. Tesco, Britain’s largest supermarket chain has started printing a chart on
their products assessing the carbon footprint of an item. “This may be as radical for environmental
consuming as putting a calorie count on the side of packages to help people who
want to lose weight,” said Trevor Datson, spokesperson for Tesco (Elisabeth
Rosenthal). I feel that it is logical to at least inform the buyer of the
origin and the cost of the product that they are about to buy. Maybe, if the
customer had more to base their product choice on then just the taste and price,
they would be more inclined to buy an apple grown locally, rather then an apple
grown somewhere in Asia that may cost twenty cents less.
The issue is not simply black and
white however. The impact also depends on the manner in
which the food was transported, not only how far. Trains are ten times more
efficient at moving food than trucks are. You could either purchase potatoes
that were transported on a truck for 100 miles, or potatoes transported on
train for 1,000 miles (DeWeerdt,
S). The greenhouse gas
emissions that resulted from these two alternatives would be about equal.
Planes are by far the most inefficient way to ship food, followed by trucks
then trains. Boats are the most environmentally friendly shipping solution,
however they are not even close to efficient enough to be sustainable and the
oil spills that are an associated risk are extremely harmful to our
environment.
The carbon footprint of food also
depends on how it is grown. Swedish researcher Annika Carlsson-Kanyama led a
study that found it may better, from a environmentalist perspective, for Swedish
people to buy Spanish tomatoes then Swedish tomatoes, because the Spanish
tomatoes were grown outside under the sun compared to the local ones which were
grown in greenhouses that rely on fossil-fuels for their sun and heat energy (DeWeerdt, S.).
This is the reason why, along with not shipping food, we need to accept that we
won’t have access to every type of food all year long. Most foods do not grow
all year long in the same place, and greenhouses are not efficient enough to be
a sensible solution. People need to understand that their environment is more
important then the latest craving that finds it’s way into ones’ head.
The cost of shipping food is too high, and there
needs to be a change. We need to release less carbon dioxide into the
atmosphere during the course of our daily lives. A great place to start would
be to change how we go about food supply. People are already taking steps in
the right direction, but we need to double up on our efforts or else, when we
run out of gas, we’ll run out of food and that day may be sooner then we think.
