OP: Whenever you’re looking for a specific plant, it helps to give the scientific name, as many plants share vernacular names or go by different vernacular names in different areas. I think that “white clover” pretty much always refers to Trifolium repens, but including the scientific name is still a “best practice” to keep in mind.

For anyone else reading, Fedco (Not Sponsored™) sells bulk white clover seed in the USA:

• Dutch white clover
• Alice white clover
• Ladino white clover
• Rivendell white clover

Syntropic agriculture (agroforestry) practices can help with adding organic matter and keeping the soil covered, even on a backyard scale. Prune trees/bushes/whatever and use that as mulch. In temperate climates, the largest pruning would be in the autumn, after trees have started to go dormant, and this pruned material would provide additional soil cover around the trees over the winter, even helping to protect young trees’ roots from frost damage.

Animal agriculture is the leading cause of climate change.

“This demand will require approximately 80 percent of existing forests and shrubland to be converted into land devoted to raising animals. Such a trajectory would have devastating consequences for us and the planet,” Professor Knight said

Solving climate change requires shading out the bullshit.

Properly scaled up, this type of community reforestation effort could work.
