Milkweeds (Asclepias Spp.) Are The Required Host Plants For Caterpillars Of The Monarch Butterfly And

Milkweeds (Asclepias spp.) are the required host plants for caterpillars of the monarch butterfly and thus play a critical role in the monarch’s life cycle. The loss of milkweed plants in the monarch’s spring and summer breeding areas across the United States is believed to be a significant factor contributing to the reduced number of monarchs recorded in overwintering sites in California and Mexico. Agricultural intensification, development of rural lands, and the use of mowing and herbicides to control roadside vegetation have all reduced the abundance of milkweeds in the landscape.

Biogas is a mixture of different gases produced by the breakdown of organic matter in the absence of oxygen, called also anaerobic digestion. It is produced from biodegradable materials and more than half of the resulting gas is methane. You can run that through a propane burner or a stove, and worldwide, lots of subsisting people do. It’s about as close to free fuel as you can get. 

Of course, if you source a self-renewing pest crop like kudzu to produce your fuel, it becomes even more cost-effective. Of course, nothing is truly free. There is some physical labor involved in maintenance and cleaning.

Cost of overhead is minimal, and a 55-gallon drum biodigester can be hacked together from found items and salvage with minimal skill. Unless it’s larger than that, a digester setup should take no longer than one afternoon.These DIY pages are pretty concise, with detailed shopping lists. If you want this to happen, it’s not hard.
