The message
from "Robert E A Harvey" contains these words:


Unless there are any dangerous species in there - like ragwort - you could
consider a couple of goats, and get fresh milk too.

Except that in order to get fresh milk from goats, first you have to
let them breed, and dispose of the male kids because they stink when
they reach sexual maturity. Then having removed the kids you have to be
there, twice every single day without fail, to milk the lactating
shegoats. Meanwhile, if you or the neighbours have a hedge, the goats
will eat that in preference to weeds. They will also need a weatherproof
shelter, somewhere else to store their winter feed, worming, and vet
care occasionally.

IMO you'd be better spending all that time effort and money on making
a garden. Smother the weeds, and keep cleaned ground clear, by covering
it up to exclude light. Old cardboard cartons, carpets, tarpaulins, or
black plastic, will do the job.
