Human beings have gotten appreciably better at picking up after their dog has done their personal business, of which, at the present time most of that dog waste is thereupon placed into a plastic bag, in which, ultimately that plastic bag is deposited into the trashcan of that person's property, in which its final resting place is the landfill. Logically, it doesn't seem to make a lot of sense that people utilize a sophisticated sewage system to take care of their human waste, effectively; whereas for dogs, of which, some of these dogs can weigh upwards to 100 pounds, have their waste, untreated, thereupon placed into a plastic bag, and ultimately deposited into a landfill.
For eons of years the waste of animals, and particularly barnyard animals, have often been utilized as a form of manure, and in recent years, as even a form of biogas and fuel producer. It doesn't take any real stretch of imagination to understand that considering all the dogs and their waste that is produced each and every day, that simply throwing away their waste into a landfill is not the best solution for taking care of this issue in a sustainable and meaningful way, which has taken into proper consideration the possible productive uses of dog waste.
All of the above, would seem to indicate that just as it has taken a long period of time to encourage dog owners to deal with their dog waste proactively and responsibility; that the next and necessary step to take thereafter is to be one in which that dog waste once collected is dealt with in a way that will utilize such waste for a purpose that will ultimately put that waste to good use; for it is known that dog waste, properly dealt with, can create good compost as well as biogas.
This would signify that more communities should educate the public about the value of being a good dog owner by their recognition of the need of ultimately depositing dog waste into well located and designated, community dog waste bins that would thereby collect that waste for the very purpose of creating good compost with it, or possibly biogas.
Again, it's a fallacy to believe that the mere picking up of dog waste and then the deposit of it into one's trashcan has somehow made that dog waste, disappear; though, it is true that it is now out of sight, yet, it is also true, that landfills are not the ideal best resting place for dog waste, and therefore a more comprehensive solution is necessary of which, the voluntary participation by dog owners to these community programs addressing such, is of absolute importance.
Those that are pastoral farmers, are experts at not wasting the waste so produced by their animals, of which, this is of benefit not only for those pastoral farmers, but to the society as a whole. Those that own dogs should want to do their part to see that they are also responsible stewards by having the same sort of progressive mindset.
