Let's all remember that while jet aircraft emit much more than other forms of transportation, this is nothing compared to the emissions of animal agriculture.
I agree that while reducing emissions from air travel is beneficial, it isn't enough of a solution. However, I think that "pissing off many normal people" is inevitable in the process of arresting climate change, as eliminating animal agriculture is necessary in order to solve the problem. People won't like that.
Old-growth forest stores more carbon than younger trees, so continually "recycling" fast-growing plants is not superior to letting the forest grow. A combination of syntropic agriculture and forest conservation would probably be more effective.
Syntropic agriculture practices achieve this and some semblance of a forest at the same time. Chop and drop. Smother the grass with mulch.
As others have suggested, shade out the bullshit with a diverse array of fruit trees and other useful vegetation in order to reclaim the land and grow an abundance of food at the same time. Even if you can't devote much time and energy to it, planting some vigorous (ideally native) pioneer species and hardy fruit trees and then just tossing seeds in there on a regular basis will go a long way toward exterminating the grass. I also second the recommendation of clover as a groundcover.
Let us also not forget the importance of syntropic agriculture practices for sustainability. Tree-based food production is the most effective way to maintain (and even improve) fertility, biodiversity, and habitat for free-roaming animals.
Let us also not forget the importance of syntropic agriculture practices for sustainability. Tree-based food production is the most effective way to achieve "a healthy, diverse ecosystem" on the veganic farm.
I think that "contaminated manure" is a bit of euphemism, don't you? Any time that I read about these shit-borne infections, I am reminded of this:
