There is a free online worm composting course being offered by the city of Plano, Texas. Click on the Indoor Worm Bin leaf at the top of the page after the introduction. As our landfills fill up with an unnecesary percentage of food scraps, cities and governments are encouraging people to learn how to compost food scraps. This would take part of the load out of the landfills and also create great compost for our yards and gardens for free. This is an interesting and educational project for adults and children.
Here is a great YouTube about the benefits of worm composting.
