Hi, A farmer can fix a snail/slug problem by letting geese loose on the crop. They will happily hunt them down and eat them. With as side benefit that they leave fertilizer behind in the field, lay eggs, and occasionally provide a meal themselves.
Regards, Robin van Spaandonk The future of computer memory clearly lies with multi-layered SOT-MRAM. Fast as SRAM, dense as NAND, very low energy due to non-volatility, and near infinite rewrites.
