...WELL, NOT EXACTLY.
Summary:
This article expands on the impacts of the livestock sector
on our environment, and although livestock can positively impact the
environment, it focuses more on the negative effects. The article goes much in
depth about the specific impacts of livestock on land degradation, water
pollution, and biodiversity loss, but I am going to focus more on its
association with greenhouse gas emissions. The livestock sector’s role in
global warming is often one that goes unnoticed, but is actually responsible
for 18% of greenhouse gas emissions. This is said to be even more than the
amount of emissions released by transportation. Feed crops used in the
livestock sector continue to expand and cause increases in carbon dioxide.
Emissions are even greater for other gases with potential to warm the
atmosphere, such as methane and nitrous oxide. One way these harmful emissions
can be reduced is sustainable intensification livestock and feed crops. Basically,
by reusing plots of land rather than expanding them, we can cut down on
deforestation, and in result greenhouse gas emissions.
Reaction:
One of the things that surprised me the most in this article
is that fact that livestock production emits more greenhouse gases than
transportation. It’s actually still pretty difficult to believe, because with
the extent at which cars, trucks, and other vehicles are used on a daily basis…
It’s just shocking to realize the shear amount of land and food we have to be using
to compete with transportation. This article was also the first time I had ever
heard or read about the idea of livestock being harmful to the environment. I
agree with the article in saying that it is something that goes unnoticed, and
it’s interesting to see what other major environmental factors it impacts as
well. With that being said, I suggest you guys read the whole article, it is
actually pretty informative.
Thoughtful Questions:
1.
What characteristics would a sustainable
production system exhibit?
2.
Aside from the negative impacts of livestock,
what are the positives?
3.
What can we do to the land to make it more
reusable? Because all of the nutrients in the soil would surely get used up after a while.
4.
What other agricultural processes harmfully
impact the environment on a large scale?
5.
If a train leaves Chicago at 3 p.m.
heading east, and another train leaves Tokyo at 7 p.m. heading southwest, what
is the square root of the sun?
