Organic food is better for the environment

Organic foods promote healthier and moresustainable use of natural resources. Modern farming methods, includingexcessive use of chemicals, have led to a decline in soil fertility, and anincrease in salinity and blue-green algae in waterways over many years. Organicfarmers try to minimise damage to the environment by using physical weedcontrol, and animal and green manure. 

Organic food and ethics

Organic foods promote more humane treatment ofanimals, as well as providing meat that is free from hormones and antibiotics.Also, some people worry about the long-term health, economic and environmentalconsequences of GM foods and choose organic foods in support of an industrythat does not use GM techniques.

Organicfood and nutrition content

Several studies have compared the nutritionalcontent of organic and conventionally grown plants, and most have shown nosignificant differences in key vitamin and mineral content. However, althoughthe differences are small, research has shown that some organic food has:

·        Lower nitrate levels

·        Higher vitamin C levels

·        Higher levels of selenium.

Reasonsto buy organic food

Most people buy organically-grown foodproducts because they are concerned about pesticides, additives, antibiotics orother chemical residues. Although pesticide residues in fruit and vegetablesare monitored in Australia, many people believe organic food is healthier. 

Pesticidesand other chemicals in organic food

Organic foods are not necessarily completelychemical free. They may be grown on land not previously used for organic foodproduction and, therefore, might contain chemical residues. However, thepesticide residues in organic food are considerably lower than those found infoods produced with synthetic chemicals.

Certain naturally occurring pesticides,including pyrethrins, light oils, copper and sulphur, and biological substancessuch as Bacillus thuringiensis, are permitted for use inorganic farming.
