When you switch to organic food, producers will get a boost to bring more farm areas under organic farming and this will have a number of beneficial effects on Australia’s environment.
First, just think of all the pesticides and chemicals that is poured into the conventional agriculture. When the farm becomes organic, the land no longer receives such chemicals. The land will then find itself going back to a natural state free from all kinds of harmful chemicals.
The soil, water and air in and around the farmland will also come back the state of nature.
Second, organic farming promotes soil health and strengthens the ability of soil to support sustainable farming. When pesticides and chemicals are avoided, a large number of soil microorganisms become active to support a healthy and living soil.
Third, eating organic and promoting organic farming helps combat climate change. In a paper published in the highly respected scientific journal Nature in 2018, a group of researchers have found that organic peas farm ed in Sweden can sequester 50% more emissions than conventionally-grown peas in the country.
Fourth, organic farming also reduces soil erosion, especially when tillage practices are minimised, and mixed cropping patterns are followed.
Fifth, organic farming is also found to conserve water. Australian agriculture is facing water scarcity and challenges related to drought are getting more severe under the changing climate. Effective use of mulch and optimising soil work can reduce water use in farming. Waterways also benefit profoundly when farmlands do not discharge chemicals.
Sixth, organic farming also contributes to ecosystem health and regeneration. Organic farming is more biodiverse than conventional farming. When insecticides and pesticides are not used, the population of insects and plants will grow, thus contributing to biodiversity of the region. A report by The Guardian dated 14 February 2019 says that “Buying organic food is among the actions people can take to curb the global decline in insects” drawing on scientific research. A paper published in the scientific Journal of Applied Ecology (dated 8 February 2020) found that organic farming benefits birds most in regions with more intensive agriculture.
