An example of pest invasion.<br />
Although intended to improve food quality and quantity, pesticides have had a variety of<br />
environmental impacts. Although not by design, 95% of all pesticides move to unintended destinations,<br />
killing species unrelated to farming (Sustaining <strong>the</strong> earth, 2004). Pesticides reduce biodiversity by killing<br />
a large number of soil-borne organisms as well as miscellaneous plants and animals. During <strong>the</strong> Green<br />
Revolution, pesticides were spread throughout developing countries. This widespread use of poisonous<br />
chemicals severely impacted <strong>the</strong> local environment around farms, affecting plant and animal life and<br />
bringing multiple species closer to extinction.<br />
Fertilizer Production and Soil Depletion<br />
A fertilizer is a substance that is added to soil to provide nutrients for crops. These nutrients were<br />
often used to replace nutrients used up by previous crops, often due to <strong>the</strong> over farming of farmland. A<br />
main part of fertilizer is fixed nitrogen (usually in <strong>the</strong> form of ammonia.) In <strong>the</strong> natural nitrogen cycle,<br />
bacteria fix <strong>the</strong> nitrogen that is used by plants.. The industrial fertilization process fixes unnatural<br />
amounts of nitrogen from <strong>the</strong> atmosphere into soil, allowing for more crops to be grown using rich soil.<br />
Fixing large quantities of nitrogen from <strong>the</strong> atmosphere has had a number of less predictable<br />
environmental effects, including low oxygen levels in water, heavy metal and radioactive element<br />
accumulation, and an increase in <strong>the</strong> quantity of greenhouse gasses in <strong>the</strong> atmosphere (Bodelier, 2000).<br />
Fertilizers also can cause chemical burns on nearby animals and plants.<br />

Political Involvement<br />
The Green Revolution was riddled with political and socioeconomic strife due to various<br />
unforeseen effects of <strong>the</strong> new agricultural production. The most brought up and extremely detrimental<br />
effect was <strong>the</strong> destruction of much of <strong>the</strong> supplemental diet of poor peasants and farmers. The promoted<br />
use of pesticides destroyed weedy vegetables present throughout <strong>the</strong> fields, in turn destroying <strong>the</strong> main<br />
