There are many reasons why someone might opt for a regenerative farming approach to growing and raising animals today.
Some investigations into regenerative farming have found that it could possibly help to allegedly boost nutrient density with food, among providing other possible benefits to communities.
Restoring soil health
There has been a rise in interest surrounding regenerative farming in various regions as more look to transitioning their farmers to this approach.
Overall it could be described as a more "soil friendly" approach to growing and farming in general.
Some have argued that this might be a superior method for farming and that's why you can find a number of individuals who are passionate about spreading the word and teaching this way of growing and farming.
For many they've found that this form of farming works best for them and their communities.
For those who are making it work it might not take them long to figure out if they can do it in a cost effective way. If it is cost effective in providing multiple benefits then that will help more to engage with regenerative farming and spread the word about it too. For those seeing the outcome firsthand, why wouldn't they continue with it and try to educate others on the option?
If it does help to bring benefits to what is being grown, the soil itself, or the animals raised on it, then that then trickles down provide benefit to the community these farms serve in as well.
