Regenerative agriculture is an approach to farming that prioritises soil and environmental health by minimising synthetic inputs. [Farm manager Tim Parton] switched to using biologically active inputs after experiencing headaches and skin rashes from using pesticides. After sheep dipping, which involves immersing sheep in insecticide and pesticide mixtures to eliminate parasites, lumps would often show up on his arms. I would be a mess, but if I went to the doctors, they would say 'you've just had a reaction' and would not take it seriously," he says. Since adopting a biological farming method, Parton has not experienced any negative health impacts. He has not had to use any phosphorus and potassium fertilisers on his crops for over 10 years. He says he has observed a big increase in insect and bird species since he stopped using pesticides. Pesticides may be responsible for the loss of smell in honeybees and salmon. Despite global regulations on pesticide use, one study estimates that about 385 million cases of unintentional, acute pesticide poisoning occur among farm workers each year. A 2020 study found that of the estimated 860 million agricultural workers worldwide, 44% are affected by pesticide poisoning annually. Acute health impacts can range from seizures to respiratory depression. Pesticide exposure has been associated with conditions such as attention deficit hyperactivity disorder (ADHD) and Parkinson's disease. Pesticide exposure has also been linked to sensory deterioration.
