|Organic farms are very environmentally friendly thanks to their use of natural methods of fertilisation and pest control.
Some Non-organic farmers often use synthetic nitrogen fertilisers in order to boost the yield of their fields. Artificial nitrogen consists of natural gas and is manufactured in an energy intensive process with a significant carbon footprint. Organic farms are required by law to only use natural fertilisers, and studies show that by doing that so they can be up to 38 percent more energy efficient than regular farms.
Synthetic nitrogen is also carried by rain into watercourses, where it stimulates excessive algae growth and poisons the water. This can damage entire ecosystems and harm humans if it enters the drinking water. Organic farms, by contrast, utilise crop rotation to let the soil replenish nutrients naturally. They also use farm manure and other natural fertilisers which does not harm the environment.
|Though regulated, the majority of artificial chemicals used on conventional farms are harmful to wildlife and the environment. Almost half of the 44 butterfly species breeding in low grasslands are in decline due to pesticides and artificial fertilisation. Farmland bird populations have declined by 50 percent between 1980 and 2009.
Organic farms host more butterflies, beetles and bats than conventional farms. By using insects as weed control and letting earthworms ‘manage’ the soil, organic farms support a healthy wildlife.
Organic farms focus on natural methods to produce milk. That leads to healthier cows and, in turn, healthier milk which is good for the environment.
