Going Vegetarian will help Save the
By Stuart Gardiner
Studies on world food
consumption have shown that an affluent diet including meat
requires up to three times as many resources as a
vegetarian diet. With demand for meat on the rise, resources
already stretched and a world food shortage we are building up
serious problems for future generations.
One little known fact is that
animals produce more greenhouse gas emissions than the entire
worlds transport system!
The 3 main greenhouse gasses are carbon
dioxide, methane and nitrous oxide. All three have increased
significantly in modern times. Increases of carbon dioxide
are mainly due to fossil fuels but methane and nitrous oxide
are primarily caused by agriculture.
Methane has more than 20 times the global
warming impact than CO2 and ruminant mammals (cattle and sheep)
are responsible for over 30% of the methane generated by human
activity. With just over 3 billion cattle and sheep on the
planet and a single cow capable of producing 500 litres of
methane a day it's not hard to understand the impact they
Nitrous oxide is nearly 300 times more
damaging to the climate as carbon dioxide and 65% of it is
produced through raising livestock. When we add ammonia into the equation it all leads to a
pretty disastrous scenario.
However, it doesn't end there.
Increasingly, water is running out. By 2025 the Food and
Agricultural organisation have estimated that two thirds of the
worlds population will be living under water stressed
conditions. It probably wouldn't
surprise you to know that it takes more than 10 times the water
to produce a kilo of meat than it does to produce a kilo of
The demand for meat throughout the world
is set to double by the year 2050. In order to meet the demand
animals will no doubt be reared more intensively. How can we
continue to sustain such growth without suffering huge
It must be clear that we can reduce our
carbon footprint by eating less meat or by becoming vegetarian.
But there are many other benefits as well. We will save large
amounts of water, avoid many types of pollution, limit the
destruction of forests and reduce the amount of antibiotics in
our food chain. These are but a few advantages we would
experience by a global shift in our diets.
Let's eat green and save the
