Soils Conclusion

I thought this video "Compost. Chemical agriculture." was brilliant. It explains what chemical agriculture does to the soil really well. It also does a really good job of explaining what is wrong with organic agriculture.

Per Rebecca's invitation, I am posting the 'overview' videos I have been doing on my YouTube channel here on her weekly chains about the course.

I've had a YouTube channel for a few years and I knew that I would be too busy with the PDC to record most of my usual YouTube videos, so I decided I would do these overviews for the purpose of:

1) Getting the PDC info deeper embedded in my skull
2) Spread the concepts of Permaculture to more people
3) As a precursor to our own PDC far down the line.

I hope you enjoy:
