Organic farmers aim to produce high-quality food, using methods that benefit people and the planet.
Most of the fruit and veg I buy is from farms that are local and organic, where I can visit the farms, but I also buy organic whenever possible with other foods, as the organic label is the best indication I have that the food has been produced in a more environmentally friendly manner. In order to be accredited, or even just to market your product as organic, you must meet standards which are laid down in law and are regularly checked by a certification body. I have also met a lot of organic farmers and they are truly committed to producing the best food possible with minimal impact on the environment. Most small-scale organic farms use agroecological farming practices, which basically means sustainable farming that works with nature.
Unfortunately the same is not true of industrial farming, which constitutes the majority of the food production. Most vegans would not consider eating organic as a vegan issue, but anything that harms the environment, inevitably harms wildlife, so if you care about all living creatures, then eating organic is the way forward.
Organic food does cost more, because it’s labour costs are much higher, but there are ways to reduce the cost, e.g. by setting up a food co-op or buying group to buy in bulk together with other people. Some the healthiest foods e.g. beans, lentils and oats, are also the cheapest. Buying local produce that’s in season will also be better value and some veg box schemes do offer sliding scales for people on low incomes.
