Farmer who is for regulation: "I run my farm using regenerative practices, cover crops, compost, crop rotation, and I’ve cut back on chemical fertilisers. My soil is healthier, and I still get good yields. I think it's time more farmers made changes like this. If we all work together, we can protect our water and still feed people. I support some regulation, especially if it helps educate and support farmers to do things better, not just punish them." Farmer who is against regulation: "I rely on fertilisers to grow enough crops to feed people and earn a living. Without them, my yields drop and I can’t afford to keep the farm running. I try to be responsible, but rules that limit fertiliser use could make it harder for me to survive financially. Why should I pay the price when I’m just doing my job to feed the world?"
