The big problem with food these days seems to be with how it's raised. Given the size of the population, organic natural grown food does not grow fast enough to supply the needed food. What we are ending up with is food that is packed with hormones chemicals and who knows what and farms that are making a huge impact on the planets eco-system. Look at what is happening on the coasts where salmon farms are located. Look at how your food is raised and processed. I remember reading a study a few years back that showed the hormones in meat are causing women's breast to be larger and mature at a younger age. For proof of that all you need to do is look at the 14-16 yr old walking around now and compare them to 20-30 years ago.
Recycling waste is a great idea. I think it is better suited for animal food. I am pretty sure it would be a hard sale to humans.
