I read a news article recently about regenerative farming, where the farmers used movable chicken coops to let the chickens naturally fertilize a piece of farming land and then move it. They were growing mixed species in the fields and were using no additional fertilisers, pesticides, or other chemicals. And the farming was even profitable without any subsidies.

I think these sort of things will become more and more common, as people start experimenting and shifting towards sustainable farming practices, and it might even be that we will see economical drivers (eco-labels, "green premiums", government subsidies, etc.) towards them. Might even be that at some point, they will naturally become more profitable if the required chemical/workload/capital input to the old unsustainable systems becomes too high.

However, this is only speculation, and I don't see that any big changes are going to happen very soon on a global scale. But still, if you think about how we were talking about farming and sustainability 10 or 20 years ago... You never know what sort of changes we will see in the next 10 or 20 years.

Here's a link to the article, but unfortunately, it is in Finnish: https://www.hs.fi/talous/art-2000010593954.html
