There's one I haven't heard of before and it sounds formidable.
I'd be curious to know how and why it is detrimental to ecosystems. Does it
take over and sterilize a system? Does it cause erosion of species
diversity?
I've heard that to break up sidewalks all you need is a cordless hammer
drill and some carob seeds. Drill a hole in the sidewalk, or black top,
just a little wider than the seed and place the carob seed in the hole. The
seeds will expand and begin fracturing the sidewalk.
