I was really relieved the other day to see those sweet little bees dabbing at the yellow flowers that adorn the crawling vines I seeded all over the shelter mound years ago. Such industrious creatures! Their work is unceasing and they give more back to the world than they ever took away. If we lose them, we will truly come to appreciate the unbelievable complexity of the world in that it depends on these tiny organisms like bees and earthworms to keep the world from turning into a barren wasteland.
I have done a little research into the details of keeping a small pod of stingless bees underground to pollinate a subterranean garden. Until I get the permaculture lab built I won't know if this is really possible.
