Donkeys are now uncommon to find, except you will find them in very few places …Animals like donkeys/dogs co-exist with humans for long time.. well, One can argue, human leverages them and make them work…. , though you can also see that human protect and feed them and they help human with their natural strengths.. if we think from other angle , then by limiting such usefulness with humans, their only relevance left is slaughtering, meat etc.. ( look at china and many countries’ donkey import numbers are rapidly rising) Of course, human shall not abuse them with heavy loading and feed them properly.
