WILEY WATER WAYS
Regarding ways of keeping cattle out of water ways, what about a robotic croc. It could stealthily approach the cattle then taser one. The rest would soon learn to just stick their mouths in the water after a seeing their fellow herd members get tasered. Then a simpler mannikin could be used and the robotic one used elsewhere. The taser could be rotated around farms where cattle need access to water but you don’t want them polluting it. Perhaps councils could lend them out to farmers.
